inquiry Posted August 6, 2005 Report Share Posted August 6, 2005 Mishovnbg is BACK!!! he has played at least twice this week after months of being AOL. In honor of his return, i will redescribe this transfer opening preempts (2NT to 3D) using simple rules to describe the "strong version" of the hands. These transfers show then next higher suit and "weak" hand or a STRONG TWO SUITER (4 losers or less, 5-5 or better) EXCLUDING the next higher suit and INCLUDING the suit opened (2NT shows "hearts" when strong). Since the strong version is fairly rare (about 1/3 as frequent as the weak version) the subsequent bidding rules must be easy to remember and must be effective or it is not worth the effort. Here are the simple rules that make this very playable (in this post, only partner completing the transfer will be discussed, and no interference... similar rules cover the other auctions, and can be discussed if anyone is interested). RULE NUMBER ONE: Opener's rebid with all weak hands is pass, with strong hand he shows his two suits and his number of losers. To show two suiter with spades, rebid SPADES or the opened suit (remember 2NT shows hearts when strong). Each higher level of opener's rebid shows fewer and fewer number of losers (4 is maximum number), and in most cases, with 3 losers or less the need or lack of need for a cover for a loser in the lowest side suit. All rebids that allow responder to pick between BOTH openers suits at the same level show the mininum number of losers, a bid that forces partner to go to the next level shows one less loser, and need for the cover in the lower side suit. So the cheapest rebid that shows specific two suiters shows four losers, the next cheapest bid that shows the same specific two suiters shows three losers, and most often the need or lack of need for a cover in the lowest side suit. These can all be worked out at the table in a matter of seconds, so no memorization needed. With major two suiters, after 3H rebid (4 loser), then 3S/4H shows 3 losers, 4S/5H (2 losers), 5S/6H (1 loser). Since two suiters without spades have three possible rebids, these show need for King, then ACE then no-cover in the lowest ranking side suit. RULE NUMBER TWO: After responder hears the opening two suiter, if he can place the contract (part-score, game, slam or grand slam) by counting sure covers and having no "maybe" covers, he signs off in one or the other of partners suits. RULE NUMBER THREE: If responder is considering slam (or grand slam) he can investigate slam by a combination of denial cue-bidding (side suits below 4NT) and positive cue-bidding (4NT and side suits above 4NT) (note 3NT to play). Each of these are up the line. So if responder skips a denied suit, it promises a "potential cover" in that suit. (5NT by responder is always bid your better/longer suit == even late in auction). A jump to 4NT when 3S is available as denial cue-bid shows King of spades and ACE of lowest side suit. A bid of 4S when 3S is available as a denial cue-bid shows King in lowest suit, and Ace or King in spades. RULE NUMBER FOUR: Opener tries to signoff by bidding the cheapest anchor suit if a denial cue bid shows two losers in a suit or if the opener has no use for a cover in the other suit. RULE NUMBER FIVE: If opener does not try to signoff, he has several options. The first is if only the ACE in the other non-anchor suit is useful (then he bids the cheapest step response not in an anchor suit). Responder must SIGNOFF in game or slam if he is missing the ACE in response to such an inquiry. Or if any cover in the non-anchor is working, opener shows the presences of absenses of one or more anchor queens as follows. With both queens, he rebids in the most expensive anchor suit. If he is missing both queens, he has three rebids possible (four with both majors): he rebids 6 of the cheaper anchor suit if missing ace in the denial suit. If he has the ACE in the denial suit, and missing both queens, he rebids 5NT, or with the ACE in the denial suit, he rebids 6 of a suit below the cheapest anchor with missing both queens but six or more cards in the cheaper anchor (with both majors, 6C shows 6+h, 6d 6+S). For rules if missing just one queen, see rule SIX. RULE NUMBER SIX: Over a denial bid or otherwise, missing one queen, openers choice depends upon available room. If there is room below five of the cheapest anchor to show the ACE ask (the cheapest non-anchor bid), and two more possible non-anchor suit bids, the cheapest bid shows missing queen in lowest suit, the more expensive shows missing queen in the higher. If only one slot exist, bidding it shows a missing queen, but does not identify the suit. If no room exist below five of the cheapest, then show missing queen by bidding above it. If two slots above exist, use lower shows missing lower queen, higher shows missing higher. RULE NUMBER SEVEN: If responder does not accept the signoff his cheapest rebid ask for missing queens. Anytime after opener has shown missing queens, responder not signing off ask if a distributional king is of use. A distributional king is not a real king or singleton, but rather a combination of long in one of openers two suits, short in the other and the side suit so that all the side suit can be thrown away, and then openers losers in that suit ruffed. If you make distributional king ask in a suit you have shown honor in, you are asking for king if you hold ace, you are asking for usefulness of the "queen" if you have the king (and partner didn't ask for ACE). Here are a few example hands. [hv=d=w&v=e&n=saq3hjt7654dk96c6&w=sthak983d875ct843&e=sj542hq2dqj32c972&s=sk9876hdat4cakqj5]399|300|Scoring: IMPWest North East South Pass Pass Pass 3♣ Pass 3♦ Pass 3♠ Pass 4♥ Pass 5♥ Pass 6♦ Pass 7♣ Pass 7♠ Pass Pass Pass [/hv] 3S = rule 1 cheapest rebid showing spades and diamond (suit opened), 4 losers4H = rule 3, thinking slam so denial cue-bid at four level, 4H denies heart, shows club control (since bypassed). 5H = rule 6, 4NT would ask for club ACE, there is no "free room" to show missing queen below 5 of the cheaper suit. Opener can show missing queen in clubs by 5D and in hearts by 5S.6D = rule seven, asking if distributional king of diamonds is (now must be distributional queen) is useful..

Heart might be king or ace, as 4NT is reserved here to ask if diamond king is useful cover (since opener has sure need for diamond, but might be ace or king needed). 5NT = ask if ACE is of hearts (rule 5)7C = ends auction. Club Queen and heart ACE covers two losers [hv=d=w&v=e&n=saq3hjt7654dk96c6&w=sthak983d875ct843&e=sj542hq2dqj32c972&s=sk9876hdat4cakqj5]399|300|Scoring: IMPWest North East South Pass Pass Pass 3♣ Pass 3♦ Pass 3♠ Pass 4♥ Pass 5♥ Pass 6♦ Pass 7♣ Pass 7♠ Pass Pass Pass [/hv] 4C = Rule 1, black two suiter, 3 loser, no need for diamond cover4H = Rule 3, denial cue-bid, no heart cover, possible other covers for slam (club queen ruff for one potential cover)5N = Rule 5 missing both queens and with ACE in denial suit, jump to 5NT7S = wow.. your three losers are two black queens and spade King.

Double ! Posted August 6, 2005 Report Share Posted August 6, 2005 Ben: Your web/blog site and descriptions of Inquiry 2/1 (as far as it's gotten) are excellent. There is a lot of good, strong, and useful material there. You are to be commended; where do you get the time to work, moderate/ be a yellow/ play, and write all of this? I study your notes and descriptions when I can (and not so many typos as a previous post might have implied.) But I have a question, actually in 2 parts. 1) Are these transfer weak/ strong openings acbl legal ( I suspect mid-chart = yes). Assuming that the answer to 1) is "yes", 2) have you devised (and submitted) recommended defenses for all of these various bids? Would someone be able to use these structures should they wish to play in an acbl-sanctioned game or event? Or is this still a work in progress? (By the way, last time I looked, your chapter on Kaplan Conversion (aka Granville) wasn't accessible. Keep up the excellent work, friend. You and Misho just might have come up with some better mousetraps. DHL Quote Link to comment Share on other sites More sharing options...
hrothgar Posted August 6, 2005 Report Share Posted August 6, 2005 I believe that this transfer preempt structure is legal at the Midchart level...Whether you can get an entry into the defensive database is a whole 'nother kettle of fish...Wheter you'd want to play this is a third... I (still) think that you're trading a big downside for a relatively infrequent upside. Quote Link to comment Share on other sites More sharing options...
inquiry Posted August 7, 2005 Author Report Share Posted August 7, 2005 Thanks Double! And as Richard points out, it is Mid-chart legal. Now to Richard's other comments. The complaint against "transfer preempts" puts you at a disadvantage when you hold the weak hand. The best arguement for this was posted a long time ago by BBO gold star "Rado" who said. "When opening natural PRE the options for opps are DBL, suit....When opening transfer PRE we give 3 additional options: direct DBL, delayed DBL, DBL+DBL and low-level Que. Obviously a contradiction arises between the goal of PRE to steal space from Opps making their live harder and giving them 3 more options to describe constructively their hands. In general transfer works well when Opps are silent(constructive option), and natural is better when opps need to bid(destructive option)"So let's address this three bites of the apple issue. First, let me say that "ultimate club" and some other systems use transfer preempts as part of the system. Second Fred's teammates (Russ Ekeblad and Ron Rubin) that won the springold, and had already qualified to play in the Bermuda Bowl play transfer preempts from 2NT to 3D (same range as MisIry) and use 3H as weak both majors, and have great success with it against world class opposition, and as Fred says, they "love it" http://forums.bridgebase.com/index.php?....61547 So. let's at least agree, that the concept of transfer preempts have some advantages. Now let's deal with the three bites of the apple issue raised by Rado earlier and no doubt part of Richards comments. 1) When you have just the weak hand, if the second hand passes to wait to make the takeout double, he maybe doing so one level higher... responnder doesn't have to bid only 3 of the tranfer suit.2) If he doubles the transfer suit, to show that suit, they have to outbid you by one level if you are weak. And, if you are strong, they have just help you play the hand. 3) If they make the low level cue-bid, they just prevented the possibility of playing in three of your suit doubled.. which might have been their best spot. So not all of these are wins. But let me share some big wins. You have a goodish two suiter and open one of a suit. Next hand jump overcalls (weak) or uses 2NT (unusual). Their bidding now makes it difficult for you in a couple of ways. Difficult to convey the stregnth/distribution of your hand. And difficult if they find a good safe. Now imagine you open at three level with transfer preempt. You have taken away the preemptive overall, you have take away 2NT unususal. And if they compete, you can easily show your distribution and power with your next bid. And this doesn't even count the clarity removing these strong hands have to your 1x-p-1y-p-3Z auctions and to your 2C opening bids (no strong two suiters included, so no second suit five+). With Richard's permission, I would be happy to show "the limited" hands he has held that fit into the "MisIry" strong transfers and show how the bid would have worked (good or bad), and the results of those hands. Personalizing the results is always better than using some theoretical hands. Quote Link to comment Share on other sites More sharing options...

david_c Posted August 7, 2005 Report Share Posted August 7, 2005 Seems unlikely that this discussion is going to turn out any differently to how it did a couple of months ago, but, never mind, I'll wade in anyway. I agree completely with Richard. Yes, transfer pre-empts have their advantages. Even so ... Now let's deal with the three bites of the apple issue raised by Rado earlier and no doubt part of Richards comments. 1) When you have just the weak hand, if the second hand passes to wait to make the takeout double, he maybe doing so one level higher... responnder doesn't have to bid only 3 of the tranfer suit.OK, so I won't use "pass then dbl" to show a take-out double. I'll play it the other way round, so that the delayed double is penalty or co-operative. Then this problem goes away. 2) If he doubles the transfer suit, to show that suit, they have to outbid you by one level if you are weak.Sure, but I'm still in a much better position than if you were playing natural pre-empts, as then I would have to make a natural overcall one level higher. And, if you are strong, they have just help you play the hand.Hmm. The a priori probability of a strong hand was already rather low; if I've picked up a hand worth a natural overcall in the suit bid, then the strong option (which always includes the suit bid, if I remember correctly) is almost negligible. 3) If they make the low level cue-bid, they just prevented the possibility of playing in three of your suit doubled.. which might have been their best spot. Right, that's a good point. It's not clear that using the cue-bid to show a "take-out double" is the best defence. But if you don't want to use the cue-bid in this way, you can still play direct dbl = "I would have doubled a natural pre-empt for take-out"pass then dbl = penaltycue-bid = some two-suiter (?) None of the problems 1, 2 or 3 apply to this. It's probably not optimal, but it's still so much better than against a natural pre-empt.

awm Posted August 7, 2005 Report Share Posted August 7, 2005 Just a few comments on this to remind people of some conclusions from the earlier discussion. First, the strong two-suiters are not as rare as people believe. A priori, a 5-5 hand with four or fewer losers is about half as likely as a preempt. So when these transfer preempts are opened, it will be a preempt about 2/3 of the time and a strong hand about 1/3 (in fact this varies a bit because some of the bids have more strong possibilities than others). In addition, this probability will change somewhat in seats other than first to favor the strong hands more, because it's more likely that someone would've opened in front of a preempt. Second, most people don't have a good defense to transfer preempts. It's true that the transfer gives you a lot more bids, and this could potentially be a loss. But most people haven't discussed all the sequences, and even prepared defenses (like acbl's) tend to be incomplete and not necessarily best. Certainly in random games on BBO the transfer preempt is likely to be a huge win even on weak hands because no one will know how to defend it. Third, the field in most BBO tournaments is not that strong. This means we have to take Ben's examples with a grain of salt -- it's true that some of these strong two suiters are hard to bid, but it's also true that a large percentage of BBO partnerships are pickup pairs and somewhat below expert level, and their results will reflect this.

hrothgar Posted August 7, 2005 Report Share Posted August 7, 2005 Hi Ben Feel free to mine BBO hand records for strong 5-5 hands that I've stuffed up. There are doubtlessly a lot of them. With this said and done, I'm dubious whether its valid to compare at the table results that most likely occured playing with a pickup partner with double-dummy bidding analysis. I suspect that many of the hands will boil down to displaying the benefits of having ANY kind of systemic agreement... As I noted in the past, I think any type of analysis needs to START by examining the relative frequency of the weak and strong hand types. In all the months that you've been preaching to the great unwashed masses, you've never once provided a statistical analysis beyond mining a small number of BBO tournaments for suitable hands. Ideally, I'd like to see a Dealer Script defining both the weak and strong hand types, accompanied by a 100K simulation to define the relative frequency... (To make things easy, its perfectly all right to assume first seat opening bids so we don't need to worry about the conditional probability that 1st seat would open 2♥ given that second seat has a strong 5-5 hand. For what its worth, I think that its more likely that people will open in front of the 5-5 shape, but I could be wrong) Last (but not least). Personally, I don't get excited by methods that are designed for "bunny bashing". Methods need to stand on their own merits. They shouldn't need to rely on the assumption that the opposing pairs are too weak to have a decent defense. As I recall, I posted a pretty reasonable defense to this method last time arorund...

From the looks of things, you're assuming that the opponents are playing piss-poor defensive methods over your transfer preempt... Please track down the last set of posts on this topic and review the defensive methods that I proposed there. I think that most of your wishful thinking goes out the window...

awm Posted August 8, 2005 Report Share Posted August 8, 2005 hrothgar, I have already run the simulation you suggest. Over 100K hands, the results were: Strong two-suiters: ~800 occurrences3-level preempts: ~1600 occurrences The constraints were as follows: Strong two-suiters: any hand with 4 losers or fewer, and at least 5-5 in two suits3-level preempts: Any hand with a 7 card (exactly) longest suit, 4-10 points, 7 or fewer losers Obviously this will vary somewhat in that some 6-card preempts may be opened at the three level, some bad 7-card suits probably won't open at the three level, etc. It's hard to simulate what people will and won't preempt at the table. Also a few of the two suiters may not qualify (i.e. not clear that AK Kxxxx Kxxxx A is a transfer preempt open despite only 4 losers).

Also a few of the two suiters may not qualify (i.e. not clear that AK Kxxxx Kxxxx A is a transfer preempt open despite only 4 losers). thanks for putting in the effort... I do think that there are a fair number of 6331 hands that will be opened with a 3 level preempt. In particular, many players using "standard" methods don't have a weak 2♣ opening available and are forced to either pass 6331s/6322s with long clubs or open 3♣. In a similar vein, their are a lot of players who use some kind of artifical 2♦ opening (multi, Flannery, Precision, Rough/Frelling) who are also faced with a similar choice... I'd be curious to know what impact treating 6 carders with a long minor as three level preempts have on the relative frequency. One "easy" way to estimate this would be to us BrBr and looking at 3C/3D/3H openings made on single suited hands and then calculate the relative frequency of 6 and 7 card holdings...

inquiry Posted August 8, 2005 Author Report Share Posted August 8, 2005 Of the 1091 hand Richard has played in the current tournment databse on BRBR, thre were 18 hands opened 3C to 3H by either side). There were 9 hands among these that were opened by a person with a hand that qualifies for misiry strong version. Amazingly these match Marks predictions almost perfectly. 18 out or 1091 is 1.65% (he predicted 1.6%). The 9 hands was 0.82%, pretty much what Mark predicted (0.8%). And is actually higher than the the 1 in 3 to 1 in 4 estimate I calculated in the past. Having said that, the 1091 hands, each side opened with preempt and each side had the big hand, so your FREQUENCY of having either of these would be 1/2 of that I guess. Thanks to richard for allowing his "strong" misIry hands to be an example for us. It is true some of them will probalby be ugly, but I am sure he will have done very well on others.

Turns out with 4-1 diamonds, no grand slam can make with a club lead. To defeat 7NT from North, it takes club Queen lead, very unilkely. MisIry would get you to the 68% grand slam in diamonds (needing 3-2 diamond split) or to the grand slam in Notrump (which as you see actually did well in practice), via one of the following two auctions. 3D - 3H4S - 5NT6S - 7NT 4S = Rule 1, spade/diamond two suiter, need club cover5NT = trick to investigate suits6S = better spades (AKQJx or AKQxxx or longer. With five-five you would bid 6D7NT = you have AKQxxx of spades, AKxxx(x) of diamonds and x or Kx of clubs with a heart void. I can bid "sane" 7D or matchpointee 7NT. We haven't covered the simple rules for when partner raises your suit. Obviously you can't show everything as easily as if he didn't due to lack of room. Each bid compressess the earlier responses. The only difference is, now the "losers needing help" are converted. 3D - 4H4S - 4NT5H - 5NT6S - 7NT/7D 4H = (rules not yet stated for when the suit is raised, like here. The simple rule is the cheapest two suiter showing bid includes all the hands up to that bid. So 3S rebid here shows 4, 3, or 2 losers needing club control). 4S = The cheapest bid deny needing help in the raised suit. The more expensive show need for help in the raised suit. Over 4H "raise", 4S shows 4, 3 losers or 2 losers no need for heart. 4NT = no longer shows upper cover either (since no heart cover is needed, that would be "foolish". Here it probes number of losers). 5H = two losers5NT, 6S as original auction Is a 68% grand slam in diamonds worth it? At matchpoints for sure. At imps? All the remaing one later...

hrothgar Posted August 8, 2005 Report Share Posted August 8, 2005 Hi Ben... Quick comment: Regardless of whether we are looking at "success" or "failures", most of your examples are taken from individual tournaments... Personally, I am THRILLED when my partners in said events can follow suit. I know that BBO helps with many mechanical issues, even so 'm surprised that many of these players haven't found a way to revoke. I have a decent track record in Indys. Believe me, its not because I favour sophisticated auctions. Unless these hands feature me playing with a semi-regular partner, my primary goal with constructive hands is avoiding disaster, NOT finding "perfect" slams. HEnce the absence of cue bids, etc...

If it was comparing how well you could do, I could go back in time and pull up one with you and Ron? You and free? You and any partner you wish? I was merely noting once again that you seem to be spending an inordinate amount of time on what I consider a rather pointless enterprise... Every time you raise this topic, I make the same basic response Give me a Dealer script that I can use to precisely understand your requirements for an opening bid. Every time, you dredge out some random collection of hands from BridgeBrowser. Todays its hands that I played. Last time, it was hands from recent tournaments. I don't believe that systems should be evaluated by "cherry picking" hands, and comparing at-the-table results with a random series of partners with idealized bidding sequences generated when you're looking at both hands. This isn't analysis, this is data-mining Case in point: In what way, shape, or form does the 7NT auction that Free and I had have any relevence to the discussion at hand? As far as I understand, we're looking at opening structures, NOT responding to opening bids... If you're suggesting that AK seventh with two side kings is suitable for a preempt, then I really don't understand the methods... I've always maintained that your system will do very nicely with the strong 5-5 hands. Where we differ is how well the system handles the weak single suited hand types playing against competent opponents with a reasonable defense. For whats its worth, the main reason that I want the Dealer script is to understand what impact different defensive methods have on opening frequencies. Case in point, I suspect that its safe to ignore the "strong" hand type when designing a defense. If I have sufficent strength to act in direct seat, than the conditional probability that you hold a weak hand type should go through the roof. Ergo, its very safe for me to adopt methods that are optimized against the weak hand types. As I recall, my original defense was based arround Direct double = balanced hands and valuesCue bids = 3 suited takeoutPass followed by double = Penalty combined with a two tiered structure to show 1 and 2 suited hands. I can't help but believe that you're gonna be at a disadvantage here... Quote Link to comment Share on other sites More sharing options...

We could be missing an ace <_< Anyway, I've played transfer preempts for a very long time (but seldom at high level), and I don't have the impression it's 1/3 strong versions. It's less, a lot less. Maybe 20%, 25% at most. And indeed, with the strong versions you'll probably score opposite weak opponents (and sometimes against strong ones as well), but with the weak version you'll lose against strong opposition. So the win-lose rate is about 1-3 against good opponents. Anyway, you can't compare misiry and moscito, since it's a completely different approach: misiry openings are specific, while a strong 1♣ opening is a general bid. :rolleyes: Quote Link to comment Share on other sites More sharing options...
inquiry Posted August 9, 2005 Author Report Share Posted August 9, 2005 Let me start by apologizing for the 7NT hand, I pulled that one by mistake.. had it from the wrong side. That is a normal 1C opening bid... (well for you 2C). Next to Free, I estimated, the strong version is one in three to one in four. That is from real world data (you have to be careful, because Ghoulsh tourneys have an icncreadible number of hte strong hands... so best states is from main room). In 1091 hands, there were 26 (sorry, 18 was from earlier dataset) preempts (3C to 3H) and 9 MisIry hand. That is 1/3 as frequent. But Richard opened preempts 15 times but had only five strong MisIry hands (1 out of three). His oppenetns opened preempt 11 times, and had 4 MisIry hands (4 losers, 5-5 or better). Those sound just about right. To richard... "Every time, you dredge out some random collection of hands from BridgeBrowser. Let's stop there for a minute. Let me discuss the hands I pulled out. Here I choose to take hands you played, not random ones, but yours. Another time, I looked at every hand played on BBO Main on April 1, 2005 over a 2 hour period (20 unqiue hands qualified...see my blog for those hands). I have even taken All ACBL toruneyments for a week (picking the week BEFORE THE hands were played... hands public record anyone could easily check and published them here (after announcing the week the hands would be used). Thus, I most definetely did not hand pick them, because I have downloaded literally hundreds and hundreds of these hands which I could show some remarkable (almost unbelievable) finding of perfect fits. Despite efforts to pick hands that CLEARLY were not "cherry picked" (taking all hands, not selected ones), you accuse me of [*'I don't believe that systems should be evaluated by "cherry picking" hands, and comparing at-the-table results with a random series of partners with idealized bidding sequences generated when you're looking at both hands. This isn't analysis, this is data-mining"'Comparing with "random partners" was never the point. Get over it. I used your hands to avoid the cherry picking accusation. Comparing your RESULT obtained on the hand is also immaterial, it was did the method work. Showing all results is of course somewhat useful... but admittedly limited value, it is THE RESULT that is key (not the relative result). But quite frankly I find this accusation of cherry picking hands under these conditions both insulting and counter productive. Cherry picking would be finding perfect hands for the system and showing them. Taking all your hands, all hands from "future tourneys", all hands on a specific date/time at the very least kills the cherry picking concept. Give me a break. Your next point deals with competition when opener has the weak hand (or maybe the strong hand too). I will point out again, as I did in the first post in this thread, "Here are the simple rules that make this very playable (in this post, only partner completing the transfer will be discussed, and no interference... similar rules cover the other auctions, and can be discussed if anyone is interested). That means this thread was to highlight the rules for Denial versus positive cue bidding, looking for useful "missing queens" and finding "useful distributional kings and distributional queens". Just saying do it with STRONG HANDS without explaining how to investigate slam and grand slam when among other things, opener cue-bids and ace asking is not available. This is my addition to the theory initiated by Misho. Despite this attempt to show the the bidding logic as I said in this case with no intereference, you drag up the frequency issue again (I think this has been proven to most people satisfaction it is not SO RARE as compared to preempts. Both with real looks thrugh huge databases, and with statistical approaches) that it is not THAT RARE when compared to the preempts in these suits (not we do not use transfer preempt at all levels, and in fact, a friend of mine thinks 3S should be normal Spade preempt, 3H a weak heart preempt (or heart preempt by itself), and 3D strong heart preempt or two suiter, or perhpas just strong 3 suiter. But anyway, the frequency is somewhere between 1/4 to 1/2 as frequent. Your next point is belief that I am going to be disadvantage (I assume greatly) when i have the weak hand. From the very beginning, I have agreed that I will be slightly disadvantaged when I have the weak hand. Not always, for instance, partner may have strong hand, so no disadvantage (and maybe advantaged when he raises and we right side contract), some times, they will pretty much ignore the preempt and bid whatever they were going to do. But on some hands we will be disadvantage. No doubt some other times we will be advantaged when they bid when they really shouldn't thinking opener is light. But I have always agreed we would be slightly disadvanged in the long run on the weak hands. However, not a lot since, as I have also pointed out, pro's who play transfer preempts EVEN without a stong version and a widely accepted bidding system (ultimate club) that uses such bids. Again, of course, you are so certain the the disadvantges (with weak hands) outweigh any stong hand advantages that to play them makes no sense. So we disagree. Next you deal with competitive intervention when opener has THE WEAK HAND (I assume). And wonder why the hell I haven't pulled up dozens and dozens of hands to deal with your preferred defense to the preempt. There is a simple reason for this. There SiMPLY ISN"T enough hands in the database with transfer preempts to find how the transfer preempt does compared ot the normal preempt. So I would have to pull up hands and "guess" what the defensive bid would be.... especially since the occassional transfer preempt you find, the defenders have no such agreement. If I can't even pick hands using Future hands (all ACBL hands in one week), all hands on one specific day (the first day of the current BRBR database), all hands YOU PLAYED, without being accused by you of cherry picking perfect hands for the method, there is no *@*$#)# way I could pick hands and propose interference that would meet your satisfaction and subsequent followup. But you know what, I no longer care. I don't care if you hate it, I don't care if you think it is horrible. I am going to continue showing the "simple" rules for bidding the strong hands (and of course, the weak hands), so anyone who wants to try it can (if they like) try it, including using what ever defenses to it they like. Next... when partner doesn't simply complete the transfer (jump raise, 3NT, and new suit bids). Oh.. and i think i will show some cherry picked hands to show what can be done if I DID SHOW such hands. Quote Link to comment Share on other sites More sharing options...

hrothgar Posted August 9, 2005 Report Share Posted August 9, 2005 Few comments here, most of which are related to a central premise:The analysis technique that you are choosing is badly flawed: From my perspective, there are two main causes 1. You don't have enough examples to have anything remotely resembling a statistically valid sample. Its VERY easy to back this statement up: A) Your analysis of the results of my 3C and 3D preempts show a slight net loss in IMPs. In contrast, my 3H opening bid is aveage +6.7 IMPs... It could be that my 3H opening is brilliant in practice, while my 3C/3D openings are slight suboptimal. However, its much more reasonable to assume that evaluating the efficiency of a 3H opening based on 6 observations is suspect... B) You and Free are using quite similar methods but disagree radically regarding the relative frequency of the two hand types. Free's estimates that the strong hand type occurs 20-25%. Your experience is that its close to 33%. Here once again, its possible that Free has looser requirements for the single suited hand types, however, I suspect that its more reasonable to assume that there aren't enough data points available. C) Your own posts state that you don't have enough data points to evaluate the results from the weak hand types. 2. I don't believe that looking at Board Results are an appropriate way to evaluate the efficiency of different bids. In addition to all the sample size issues that I raise, there is another very significant problem: Recall the results of the "Swatting ther MOSCITO's" match. From my perspective, the results of that match shed VERY little light regarding the efficiency of the different bidding styles being used or the skill level of the different participants. To me, the match results demonstrated one point very clearly: Two well oiled partnerships have an enormous advantage competing against two pickup pairs... In turn, this same issue significantly biased your study when you compare the efficiency of your Misery preempts to BBO or OKB board results. There is a very simple way to sidestep these issues: Monte Carlo simulation usig a good hand generator like Hans van Staverns's Dealer or Thomas Andrew's Deal is a much more powerful analytic technique than data mining.

inquiry Posted August 9, 2005 Author Report Share Posted August 9, 2005 Free's estimates that the strong hand type occurs 20-25%. Your experience is that its close to 33%. There is a very simple way to sidestep these issues: Monte Carlo simulation usig a good hand generator like Hans van Staverns's Dealer or Thomas Andrew's Deal is a much more powerful analytic technique than data mining. Last comment on frequence. I said 1 to 4 to 1 to 3 from looking at 100's of thousands of deals using Bridgebrowser to pull the hands out. Free estimated his from his feelings based upon expereience. I am willing to accepted 1 to 4 (25%), no problem. As for monte carlo simulations, awm has told you on at least three occassions he has done this and found the frequency around 1 strong hand for every 2 weak hands. I think he underestimates the frequency (and crap) people preempt with, but his study meets you requirement, and I see no need to re-invent the wheel. Moving on know with the rules for when partner doesn't raise. We will start with no competition from the oppoents, and follow up with their bidding. RULE 8. IF PARTNER BIDS HIS OWN SUIT, it is forcing. With a weak hand, opener may, 1) Raise partners suit with a fit, or2) rebid his own suit.With a strong hand, opener must rebid in the 3)"fourth suit" (not suit opened, not transfer suit) 4) in 3NT (two suiter without the bid suit5) the "opened suit" or above a simple raise of partners forcing suit. Bids above "Raise" show their normal meaning (as if partner completed the transfer). 3NT shows the other two suit combination maximum losers, cheaper bid shows fewer losers and as soon as the bidding can back to normal meaning it does. RULE 9. If responder REBIDS his suit, it intended to play (my suit), and is not a denial cue-bid or otherwise RULE 10. If responder jumps in a new suit in response to the transfer opening, it shows a SOLID SUIT (no losers). That suit will be trumps, even if opener has strong two suiter. RULE 11. Responder bids of 3NT are to play if opener is weak, opener rebids normally if holding strong two suiter. The 3NT reply can be made when very weak and extra long in partners suit, so if 3NT bidder then rebids the "transfer suit" over partners two suit showing bid, it is to play similar to rule 9. RULE 12. IF RESPONDER JUMP RAISES, opener passes all weak hands, and bids on with strong hands. Three and four losers responses and some 2 loser responses are compressed into the cheapest responses, and a few adjustments are made. 4NT by responder now ask for number of losers instead of showing a cover. The assumption in the jump raise will include a cover in the bid suit more often than not, so when replies can show same losers at the same level, the cheaper shows no need for cover in the "raised suit" (worse news). RULE 13. If the opponents double a denial cue-bid, or an ACE inquiry, or any other artificial bid once a two suiter has been shown, PASS and REDOUBLE become the cheapest two "no signoff bids". For instnace, if they double a denial cue-bid, pass ask for spade of off suit, REDBL shows missing queen in the lower anchor suit, next cheapest non=signoff bid shows missing queen in the higher suit. Etc. RULE 14. IF opponents double the opened suit (regardless of meaning of the double), pass by responder shows a tolerance for the opened suit. A redouble show game invite in the "weak suit", and complete transfer shows total dislike for the double suit (this allows, 3C-x-p-p when opener has a two suiter with clubs, since responder has shown a tolerance, this allows 3D-x-xx-P-4H when opener has a good preempt). Over responder pass, redouble or completion of transfer, opener rebids as if no interference and LHO passed, except that opener completing his own transfer or redoubling shows weaker and stronger preempt hands. RULE 15. IF opponents overcall, and partner doubles it is for penatly, to remove you need a strong hand, and you respond as if partner passed. IF partner raise suit, bidding continues as if opponent didn't overcall and partner jumped raised. If opponent overcall (either side of table) and opener doubles, it is penalty, they have bid one of openers strong suits. If they "cue-bid" and opener doubles, it shows the strong two suiter (short in the transfer suit). If they overcall and raise, openers double shows strong two suiter. If they overcall and opener bids anything, he shows the "other two suits" using the rules of lower suit covers. In fact, five different bids can exist, so you can show specific cover needs, for instance... 3C-3S-P-P-?Pass - weak hand with diamonds3NT - diamonds and club, 4 losers4C - diamond and clubs, 3 losers Now next five bids show D/C with specific losers4D - diamonds and clubs, 2 losers, need heart QUEEN4H - diamonds and clubs, 2 losers, need heart King4S - diamonds and clubs, 2 losers, need spade ace4NT - diamond and clubs, 2 losers, need spade King5C - diamonds and clubs, need spade ACEOF opponent overcalls in a suit or doubles and his partner bids a suit, now openers double shows strong hand without the suit they bid. Double serves as the weakest group response (three or four losers), other bids show fewer losers with same refinements shown above once the level reaches the normal response level without competition. For example.. 3D - (DBL*) - Pass - 4S where DBL is takeout? DBL = Diamonds and club, 3/4 losers4NT = diamonds, clubs 2 losers, need a heart5C = diamonds, clubs, 2 losers, no need for heart5D to 6C one loser, pin point need (or lack of) for a cover. As for your "preferred method" for competition richard, I think it is not the best. I believe that awn's method (http://forums.bridgebase.com/index.php?sho...indpost&p=61409) but either is better than what most people might play without specific agreement. Awm method is similar to yours in some ways, his DBL of the transfer shows "cards" but Hxx in the "bid suits" (I assume here the suit opened and suit promised if weak). The problem with this in theory is after 3C-X-P-? advancer has to worry about the bidding going all pass when opener has clubs since the pass showed club tolerance. That will happen some of the time for sure. But what I particularily like about his method is his cue-bid ask for a stopper in the preempt suit for 3NT, and his direct seat 3NT is really good values (else double) with a sure stopper (else cue-bid). This is a very effective tool, providing an opportunity not found if the preempt had been in the bid suit. On the other hand, you mix two cue-bid (takeout) with pass then double (penatly). You win when you have trump stack behind opener, you lose when partner has good trumps on his side (since you miss chance to double). In fact, you lose more often because with trump stack in your hand, a pass will often fetch a double from partner, but once you cue-bid the chance to double is gone. So this seems a trade off, while the cue-bid asking for a stopper combined with the double showing stoppers and cards, seem a clear win (gain in clarity).

inquiry Posted August 15, 2005 Author Report Share Posted August 15, 2005 Sometimes, MisIry is like magic. Here is a hand from BridgeWorld challenge the champion auction. This is old (July 1988) the hand was deal 6 in Canadians Michael Schoenborn and Harmon Edgar versus Aussie's Barbara Travis and Sue Lusk. The deal was submitted by Gregory Arbour of Vanconver BC. [hv=d=e&v=e&w=shakq742dakj64cq9&e=sq74h8653dq83ca52]266|100|Scoring: MP 2NT 3♣3NT 7♥[/hv] Both pairs reached 6♥. Bidding with Misiry is "easy". West 3NT rebid shows red two suiter, with need for the club KING. Since EAST has the club ACE, he knows two of opener's losers are AK of clubs, the other is the diamond queen. Thus partner has AK of diamonds (five or longer), AKQ of hearts (five or longer), and no spade loser. Thus, after trumps are pulled, partner's club loser can be ruffed after throwning clubs on partners long diamonds becomes a reasonable shot. True, if partner has only five diamonds missing the jack, diamonds have to be 3-2, making grand slam roughly 68% with the worse hand partner can hold, (some 4-0 trump splits could be problems too of course). Of course partner can have six diamonds, and or, partner can have diamond Jack (as here). Magic, two rounds of bidding. Quote Link to comment Share on other sites More sharing options...
awm Posted August 16, 2005 Report Share Posted August 16, 2005 The idea behind my suggested defense is to win as much as possible when opener has the preemptive hand. Supposing 3♣ was opened, showing either a weak hand with diamonds, or various strong two-suiters. In direct seat: X = cards, something like 14+ hcp, guarantees some cards in CLUBS (minimum of Hxx)3♦ = asking for a diamond stopper, either a running suit or very strong stopperless NT hand3♥/3♠/4♣ = natural, fairly normal overcall of a 3♦ opening3NT = to play, but very sound values (else would try X)4♦ = strong two suiter, or however you would play 3♦-4♦ normally After 3♣-P/X-3♦-P-P... X = takeout, if no original X will be a "balancing" type action3♥/3♠/4♣ = natural but not as strong as in direct seat3NT = after an initial X, this is a very serious 3NT (slammish); after pass it's 2-suited t/o4♦ = four card major and 6+♣ (a tough hand to describe normally), good values If opener has a preempt, you're essentially strictly better off than you would be normally. Here are the wins: (1) If you have a pure penalty double, you can double 3♣. Often partner will now make a light takeout double of 3♦ which you can convert. This is not as nice as a "pure" penalty double, but is much superior to passing a natural preempt and just hoping partner balances on his 8-count. You can also win when you have a good hand without classic takeout double shape, and encourage partner to make a light major suit call. (2) If you have a "dubious" 3NT call (i.e. something like 16-18 flat) you can start with double. Most of the time when 3NT is making partner will act now. This means you will often avoid the bad 3NTs while bidding the good ones. (3) If you have a borderline bid or double, you can start by passing and then act over 3♦. Partner will know this is a borderline action and be less likely to hang you. (4) You now have a bid with the tough "stopper ask" hands which are otherwise difficult, as well as the tough 4M/longer minor hands. The only time you might lose when opener in fact has a preempt is on an auction like 3♣-X-P, but one would expect this to be passed out infrequently. Keep in mind that doubler has a pretty good hand including at least a little bit in clubs. How often will 3♣ actually play better than 3♦ here? I'd bet it's pretty unusual. When opener actually has the strong hand, you might lose by being unable to bid diamonds directly (well, below the five level). But you can normally make a four-level diamond call at second turn and find a sacrifice if any. If an auction like 3♣-X occurs when opener in fact has a two suiter, this can often mean bad things for the opening side. Most of the points are sitting behind opener, including at least one honor in what's probably one of his suits (clubs). Of course, the odds are against a direct-seat double when opener has the good hand. Quote Link to comment Share on other sites More sharing options...
mr1303 Posted September 1, 2005 Report Share Posted September 1, 2005 OK, I'm trying to persuade a partner of mine to play MisIry. Does anyone have a simple way of memorising the strong hand continuations? I managed to learn the symmetric relay by writing it all out, since there's a repeating pattern. Any suggestions?
