    Polish Club, preferably my own version below or, failing that, WJ2000.
  • Preferred Conventions/System Notes
    The Frencz Club: (my 2010/xx/xx version of PC - one adept until I complete it and find a partner who is eager to play his own system half of the time). The main deviations are: a) getting better definition for 1C (which should be neither a Precision 2C nor a strong unbalanced hand with another suit than clubs as the main suit), without having to pass the Wilcosz hand types. b) getting better definition for 1S, which should never be 5332. c) introducing five-card major suit answers (either opener is balanced, and the partnership has room, even when the opening is 1H, or he is unbalanced, and it should be his responsibility to introduce a four-card major). 1C shows either 12-15 balanced (without a five-card major), 15+ with clubs, 18+ balanced or a 4414. 1D shows 4+ cards (not 4333, 4432 or 5332). (11-14 with five clubs and four diamonds is possible.) 1H shows 5+ cards (5332 only if 11-14) 1S is unbalanced with 5+ cards (hence, 1N is forcing). 1N is 16-17 balanced but can be slightly weaker if opener has 5 spades (hence, few invitational bids, and more room for describing responder's hand). 2C is 11-14 with 6+ clubs or 5+ clubs and 4 cards in one or both majors. 2D shows a weak two with hearts or a weak two-suiter with spades and another five-card suit. 2H shows either 11-13 HCP in a 5332 with 5 spades or an unbalanced hand with hearts or diamonds, though the opening is not forcing (2N is forcing). 2S shows a weak two with spades (hence, more 2S 4S sequences than there would be if 2D were multi and 2S a weak two-suiter). 2N shows either a weak two-suiter with 5 hearts and a five-card minor or an unbalanced game force with spades (3C, POC, is mandatory with less than 6 points). 3C to 3S are normal preempts. 3N shows an Acol two in clubs. Over 1C: 1D denies a five-card major and some specific hand types. 1H shows 6+ with 5+ hearts. 1S shows 6+ with 5+ spades. 1N shows 5-10 with 4 hearts and less than 4 spades. 2C shows 0-5 with a five-card major. After 1C 1D: A rebid of 1H shows either 12-15 without 4 spades, or 22+. A rebid of 1S shows 12-15 with 4 spades (and perhaps 4 hearts, including the 4414s). A rebid of 1N shows 18-21. A rebid of 2C shows 15-22 with diamond shortness (4315, 3415, 4441, 4405). A rebid of 2D shows 15-22 with heart shortness (4135, 3145, 4045) A rebid of 2H shows 15-22 with spade shortness (1435, 1345, 0445). A rebid of 2S shows 15-22 with 6+ clubs and a four-card major. (2N is positive or spades) A rebid of 2N shows 17-22 with 6+ clubs and perhaps 4 diamonds. A rebid of 3C shows 14-16 with 6 clubs and perhaps 4 diamonds. Higher rebids also show 15+ with real clubs After 1C 1H: A rebid of 1S shows 15+ with clubs. A rebid of 1N shows 12-15 bal with 2 hearts. A rebid of 2C shows 12-15 bal with 3-4 hearts. A rebid of 2D shows 20+ bal A rebid of 2H or 2S shows 18-19 bal A rebid of 3H is 4414 After 1C 1S: A rebid of 1N shows 12-15 bal with 2 spades. A rebid of 2C shows 15+ with clubs. A rebid of 2D shows 12-15 bal with 3-4 spades. A rebid of 2H shows 20+ bal A rebid of 2S or 2N shows 18-19 bal A rebid of 3S is 4414 Over 1D: 1H denies a five-card major 1S shows 5+ hearts (a rebid of 1N shows clubs, a rebid of 2C shows spades). 1N is weak with 5 spades (opener must rebid 2C with 4 hearts) 2C is strong with 5+ spades 2D/2H are multi. 2S is invitational with 5 spades 4 hearts. After 1D 1H: 1S shows 5+ diamonds and another four-card suit 1N is a canape into clubs, but may conceal a strong three-suiter 2C is a diamond one-suiter 2D is a three-suiter with both majors, forcing. 2M is a limited three-suiter with that major. After 1D 1H 1S: 1N doesn't deny a four-card major, and opener must rebid artificially into a minor if he has one 2C is natural or a balanced game force. 2D is balanced 11-12. 2H is unbalanced with a diamond fit. 2S is semibalanced with a diamond fit. Over 1H: 1S is a 1N answer, but doesn't deny spades. 1N is invitational or better, but denies a good heart fit or 5 spades. 2C is either a weak raise with 2/3 hearts or an invitational hand with a misfit (opener bids 2D/2H with less than 19 points). 2D is invitational or better with 5+ spades. 2H is normal. 2S is invitational with 6+ spades. After 1H 1S: 1N shows 4 clubs, a weak notrump with 3 clubs, or a 1543. (2D by responder now shows 5 spades.) 2C shows 4 diamonds or a weak notrump with 2 clubs. 2D shows 4 spades. 2H shows 6+ hearts. Over 1S: 1N is forcing, but denies a spade fit 2C is invitational or better, but denies a spade fit or 5 hearts 2D is either a weak raise with 2/3 spades or an invitational hand with a misfit (opener bids 2H/2S with less than 19 points) 2H is invitational or better, but some invitational hands transit through 2D 2S is normal 2N is invitational with a spade fit 3C/3D/3H are forcing with a spade fit (and show hand types, not suits) 3S is preemptive

    I would rebid 3♣ because that does not seem completely wrong, only possible bad judgment (which often means insufficient codification). This being said, if 1N should be strong and a 2♥ opening should cover the minimum 5332 with five spades and perhaps a few unpleasant and uncommon hand types, you might decide that 2N by opener over 1♠ 2♦ shows clubs, which would allow responder to merely complete the transfer when he doesn't feel like saying anything more useful. Another idea would be to use a multi and open 2♠ to show a minimum opening with six spades and rebid 2♠ to show a hand which lacks definition, but at least isn't a minimum with six spades. Maybe that's just me, but I don't understand why we're supposed to open 1♠ as often as 1♥.

    I meant: A quick and dirty simulation (dealer -s0 on ubuntu) with the following file predeal east SAJ, HKT86542, DA, CAK4 condition hearts(west)<=3 && spades(west)<=3 && hcp(west) <= 12 - 6*shape(west, x3xx) && hcp(west)>=4 produce 20 action print(west) gives 1. QT2 Q3 98753 T73 2. Q92 J3 J654 QJ75 3. T72 - QJT74 JT976 4. Q3 93 Q98542 QJ3 5. 764 93 K9874 J53 6. 765 QJ KT632 J62 7. K4 A3 K632 J7532 8. 85 Q7 QT754 T975 9.

Q85 Q3 K85432 75 19. 5 A3 QJ972 Q7532 20. K6 A3 T7643 QJ75 So, I guess there are enough patterns which make 3♣ worth bothering with. It surely helps that responder shouldn't have four spades (and therefore no 4144). (5♣ - and 6♣ by opener - with hands 3, 14 (hmm) and 15, 4♥ with hand 11, 4♣ with hand 13, 3♦ with hand 16, 3♥ showing exactly two cards with all the other hands?)

    Maybe I am not answering the question, but over an unbalanced 1♦, should responder still show four-card majors? It seems to me that 1♥ should merely relay for a possible four-card major, and other bids should cater to five-card majors.
  6. Antoine Fourrière
    I would pass now, but I think I might have opened a (strong) notrump, and bid spades up to the three-level if given the opportunity. I wouldn't be too happy with rebidding 2♠, 3♠ or 2♣ after 1♠ 1N.

    2♣ followed by 3N.
  9. Antoine Fourrière
    I didn't answer your poll, but it seems to me that the worse in Precision is a tossup between the amorphous 1♣ and the nearly as amorphous 1♦. Besides, there is also a useful space principle frequency paradox (which you hinted at, and which affects Standard to a lesser extent). 1♣ is less frequent than 1♦, 1♥ doesn't occur often enough, and 1N is too frequent, which implies that responder has too many hand types to show for a frequent four-point range. On the other hand, I have mixed feelings, but no real distate, for the original 2♣ opening, which Polish Club has kept (in its WJ version). So I think you are right to revamp the 1♥ opening, but replacing hearts with clubs doesn't do the job IMO. I would prefer: 1♣ 15(16)+ 1♦ 10-15 unbal with 4+ diamonds 1♥ 11-14(15) bal or (semi?)three-suiter short in diamonds 1♠ 10-14(15) 1N 10-14(15) with 5 hearts and a 4 card minor or 6 hearts 2♣ 11-14(15) with 6 clubs or 5 clubs and a 4 card major 2♦ weak two in hearts (7-11) or weak two-suiter with spades (8-10) 2♥ Flannery 2♠ weak two in spades (6-10) 2N 10-14 with 5 hearts and a 5 card minor or 7 hearts Over 1♥, it could go pass to play, either 5 hearts or various very weak hand types 1♠ transfer to notrump, not caring about opener's range for game purposes 1N 0-(bad)11 with 4 spades, retrieving the 4-4 spade fits. 2♣ invitational stayman 2♦ 5 spades 2♥ invitational with 5 hearts 2♠ game forcing with 5 hearts After 1♥ 1♠ 1N, it could go 2♣ balanced, no slam interest, intending to show exact pattern 2♦ balanced, slam interest, asking about range and shape 2♥+ shortness After the Majeure d'Abord 1N showing hearts, responder - could pass with a heart shortness - could ask about range with 2♣ and stop in 2♥ After the (too wide) 2N opening, 3♣ would be pass or correct and 3♦ a GF relay.
  10. Antoine Fourrière
    It seems to me that South's hand is worth bidding game, but isn't worth jeopardizing that game with a descriptive process. There should be a specialized answer (3♦?) showing either a minimum balanced game force or an in-between hand with distributional values (5422, (good5)322, 5431 with a three-card fit), whose main purpose would be to allow opener to bid four if he judges there is more to lose than to win by inquiring further.
  11. Antoine Fourrière
    The people who are ruling conventions are, quite logically, of the convention-ruling ilk, and tend to rule against new conventions, which means banning them. (Of course, they don't mind at all, they view their kind of bridge as the only true bridge.) But (although it never was their problem), I think it would be fairer to merely permit an opponent to know the longer suit. Say you open 2♦ Multi (or Wilkosz) and a poor newbie (or ACBL player) is unable to come up with a defence. Instead of granting him the right to force you to play his system, why not give him only the right to force you to disclose your longer suit(s) when he has a hand which he feels would be otherwise too difficult to bid? There would be no ambiguity, but your pair would still retain some advantage of your convention (opening more hands, right-siding some of them, allowing responder to preempt immediately when overcaller insists on extra disclosure). I guess Multi or Wilkosz would remain valuable bids, contrary to a 2♥ opening showing a weak two-bid in either major (see Martel's interview on Glen Ashton's site for another, possibly well-founded, complaint about insufficient disclosure), or a 2♠ opening showing a weak preempt in any suit. (I am not implying that such a rule would be better than an anything goes approach, but it wouldn't be nearly as bad as the present situation.)
  12. Antoine Fourrière
    Playing kickback, one could think of 1♠ 2♥ 4♣ 4♠ 5♦ 6♠. 2♥: please raise me with three cards, 4♣ splinter, 4♠ RKCB for hearts, 5♦ 2 keys, no ♥Q.
  13. Antoine Fourrière
    In my system, a 1N opening has only a two-point range (perhaps two and a few tenths) The idea is that responder usually shows his pattern and opener mostly relays. .FIRST SET OF QUESTIONS: Partner opens 1NT. The way you play, what do the following responses mean? 1) 2♣ - do you play Garbage Stayman? Puppet, denies a five-card major No, opener always rebids 2♦, even with a five-card major. 2) 2♠ Balanced game force, with either five spades (so that a rebid after 1N 2♥ 2♠ shows an unbalanced hand, as would a rebid other than 2♠ after 1N 2♦ 2♥) or values for slam. Opener rebids 2N without a spade fit and something else with a spade fit, then completes his pattern if responder reasks. With mere game values over 2N, responder bids 3♦/3♥/3♠/3N with 5(332)/5224/5242/5422. 3) 2NT Club transfer, either 6+ clubs (not 6322 or 7222 if GF) or 10+ club-diamond GF two-suiter, including 4 clubs and 6 diamonds. All 10+club-diamond two-suiters rebid 3♦. 4) 3♣ Diamond transfer, 6+ diamonds, 6331 or 7321 (7330, 8221...) if GF (no super-acceptance). 5) 3♦ 6 diamonds and 4 of a major 6) 3♥ 6 clubs and 4 hearts 7) 3♠ 6 clubs and 4 spades 8) 4♣ nothing 9) 4♠ natural, as would be 4♥. 10) 4NT nothing, the 2♠ relay will provide some information. 11) 5NT nothing SECOND SET OF QUESTIONS: For this set of questions, assume that the bidding has started 1NT- 2♣. I will provide opener's rebid and then ask you for the meaning of Responder's rebid. A) Opener rebids 2♦, what does responder's rebid of 2♥ mean? 4432 or 5m332, no slam. Opener keeps relaying and responder has enough room to show his number of hearts and spades in case of a CTC hand or a 5-3 major fit. (1N 2♣ 2♦ 2♥ 2♠ 2N shows 4 hearts, because responder will have to play a 4-4 heart fit, and there is no need to disclose his remaining pattern; 1N 2♣ 2♦ 2♥ 2♠ 3♣ shows 4 spades without 4 hearts, higher third-round bids by responder show respectively a heart doubleton, a spade doubleton, 3352, 3325.) B ) Opener rebids 2♦: what does responder's rebid of 2♠ mean? 5m422 or 6m322, no slam. Opener also keeps relaying. C) Opener rebids 2♦: what does responder's rebid of 2NT mean? (so far I anticipate fairly consistent answers). 4-1(0) in the majors D) Opener rebids 2♦: what does a 3♣ rebid by responder mean? club shortness E) Opener rebids 2♦: what does responder's rebid of 3♦ mean? diamond shortness F) Opener rebids 2♦: what does responder's rebid of 3♥ or 3♠ mean? (Anticipate a lot of Smolen answers here.) 3♥ 31(54), 3♠ 1345, 3N(or more) 1354, barring possible voids. G) to O) Doesn't happen.
  14. Antoine Fourrière
    A Polish 2♣ opening has a closer range than in Precision, say an average 11 to 14 with five clubs and a four-card major, or a good 10 to an ugly 14 with six clubs. Thus invitations aren't absolutely necessary (although some rebids by responder are more (2N over 2♥, 3M) or less (3♣) invitational), and you can even bid 2♦ with something like Q9xx KQJxx Txx x and no intention to invite (provided you scrap the 3♦ response showing a maximum with six clubs and four diamonds). Over a 2♥ response, 2♠ should be scrambling with a singleton, not completely unlike a 2♠ rebid after 1♠ 1N 2m 2♥), and opener won't scramble with KQxx xx Kx Axxxx. So I think West should have bid 2♦ and raised 2♠ to 3♠.
  15. Antoine Fourrière
    3♠. Partner would have overcalled with six diamonds and five hearts.
  16. Antoine Fourrière
    3♥. I wouldn't pass after 3♣ (3♥) Dbl (Pass), so I might as well show my hand type now. Hope that partner hasn't six hearts.
