olien Posted October 21, 2009 Report Share Posted October 21, 2009 What is a good way to play 2NT opening as? Would prefer NOT natural and NOT both minors. The 2N opening would be in the context of the following opening structure: 1C 16+ any (18+ if BAL)1D 10-15 HCP 2+D (possible S or C canape)1M 10-15 HCP 4+M (possible canape in any suit)1N 14+-17 BAL2C 10-15 HCP 6+C or 5+S 4+C2D 10-15 HCP 5+H 4+D2H 10-15 HCP 5+H 4+C2S weak Quote Link to comment Share on other sites More sharing options...
blackshoe Posted October 21, 2009 Report Share Posted October 21, 2009 bad 3 level preempt in either minor. Then 3m is a good preempt, one which you'd be happy to see partner bid 3NT. NB: don't know where you play, but in the ACBL, this is a mid-chart convention. Quote Link to comment Share on other sites More sharing options...

NB: don't know where you play, but in the ACBL, this is a mid-chart convention. I always thought that 2NT showing a bad minor preempt was brown sticker by WBF. And yet it's allowed in midchart in US? The US is bizzare on what's allowed and what's not... Quote Link to comment Share on other sites More sharing options...

jdonn Posted October 21, 2009 Report Share Posted October 21, 2009 I'm going against the conditions, but make 1NT 14-16 and 2NT strong, there is no other good use you'll get another than something very random and preemptive. Quote Link to comment Share on other sites More sharing options...

vincit Posted October 21, 2009 Report Share Posted October 21, 2009 I like to play it as a 65 or a Gambling diamond based (AKQ 6 or 7) because it fits well in my system It is followed by 3C relay then you show your shape: 3D = 5S6D3H = 6D5C3S = 5H6D3NT = Gambling diamond based Note that you show your shape two-step under so that you can make a proposal at 3H on 3D Quote Link to comment Share on other sites More sharing options...
olien Posted October 21, 2009 Author Report Share Posted October 21, 2009 In reply to jdonn's comment This is a relay system, so probably best not to use natural 2N 1C-1D/ 1H=20+ anySo 1C-1D/ 1N=18-19 and stronger ones go via 1H. We also chose the nt range we did so that the balanced hands that we open 1D tend to be slightly more sound. Quote Link to comment Share on other sites More sharing options...

We also chose the nt range we did so that the balanced hands that we open 1D tend to be slightly more sound.What if partner bids something other than 1D over 1C? Can you still work out all your notrump ranges? Or does partner always respond 1D? Assuming you can answer these questions, there still might be something to be said for 1C-1D-1H=22+ if balanced, else 20+. I have never played a relay system so the above could well be nonsense :) FWIW I am always happy to play against opponents who use 2NT as some bad preempt.

Seems to me 2N would work identical to a multi 2♦. Would you 'prefer' to play against multi vs other types of 2 bids? I wouldn't, but thats me. No one has mentioned this but calls of this genre are worlds apart from any transfer preempt. By the way, how would you simply show clubs at R1?

Fred GitelmanBridge Base Inc.www.bridgebase.com Why is this?- Easy to defend against- Easier to extract a penalty than natural 3m openings and penalties available more often if you preempt with "bad hands"- Nice not to have to commit to bidding or passing immediately with marginal hand for overcall or takeout double- When they open 2NT or 3m and you end up as declarer or on defense (ie on every hand) you will know more about the unseen hands than you would against opps who played wider-ranging 3m preempts or who don't preempt at all with "bad hands"- When they pass sometimes you will be able to draw effective negative inferences (this is one of the main reasons I think 10-12 notrumps are so awful by the way) Probably I could think of some more reasons...

awm Posted October 21, 2009 Report Share Posted October 21, 2009 For a while I tried playing 2NT = strong two-suiter (5-5 or more) without spades. This has a number of advantages: (1) When you open 1♣ strong with these hands, opponents are often in the auction. Bidding 2NT directly shuts them out. (2) These hands do better when opener describes, but it's hard to work them into reverse relays. So opening 1♣ and hearing about partner's shape and values is often the wrong way to go about it. I eventually gave up the experiment because the methods we were using over 2NT (which worked pretty well) were too much to remember. But it's pretty similar to Inquiry's stuff, although without the weak option. Another idea is to play 2NT=6+ in a particular minor and 4 in a particular major. This is about as frequent as 2NT=minors, acts as a very annoying preempt, and might take a problem hand out of your 1M openings. If the minor is diamonds, you have plenty of room to play 3♣=relay over it too. Quote Link to comment Share on other sites More sharing options...

kenrexford Posted October 21, 2009 Report Share Posted October 21, 2009 There are all sorts of things that in theory make sense. Weak with both minors or with just diamonds (correct 3♣ to 3♦) would allow 3♦ for some other purpose (maybe both majors). Tossing in a multi aspect, where 2NT might also be strong, might be fun. Or, 2NT as weak with both minors, weak with judt diamonds, weak with both majors, or weak with just spades could also be unwound, maybe, and might open up both 3♦ for some purpose and 3♠ as, say, a gambling-expected relay to 3NT, also possibly stacked.

olien Posted October 21, 2009 Author Report Share Posted October 21, 2009 In reply to Fred's question about what happens after 1H+ responses to 1C is opener usually relays with a balanced hand and gets a good idea of responder's overall strength and usually learns exact distribution and can make appropriate slam/game decisions. Anyways, I was thinking of a 2N opener as weak both majors (5/5 NV and 6/5 V). Is this as bad as a 2N opening weak both minors? How about 2N as weak S + H/D like used by bates and sontag?

Multi is inferior when you actually have a weak 2, but hopes to make up for that by the gains it gets from freeing up the other 2M bids as something.

benlessard Posted October 22, 2009 Report Share Posted October 22, 2009 im satisfied with our 2nt weak preempt in a minor (our 3m could be opening hands). Its easy to defend but the upside are there. You open 3m instead of 1m. Intermediate 3m bids is where you will win most impsYou open 2Nt instead of 2D/pass (if you got clubs)You avoid some hopeless 3Nt.1m followed by 2m show extras.1m followed by a jump to 3m is forcing or almost forcing.a non vulnerable 2 level is often 5 cards. Anyway its hard to find an alternatives. 2nt for whatever strong hand will be a slam killer.In an ideal world you would want security, frequency, precision and preemptive effect, and being hard to defend.

straube Posted October 22, 2009 Report Share Posted October 22, 2009 First, explain more about your 2C opening. Is it single-suited clubs or 5+S/4+C?I've never seen 2C hide a spade canape. Is that common and why do you do that? I think 2C would work better as six clubs or 5 clubs with 4 spades. Then 1S-1N, 2C=5S/4C awm was on the right track, I think. Use 2N to fill a gap in your system. You could do... 2N=weak (11-13) opening hand single-suited diamonds Then 1D-1M, 2D=good major raise 1D-1M, 2N (or higher)=good single-suited diamonds You don't really need 2N to show 6m/4M because you have other ways of showing this. You could use it to show 6D/4C which might otherwise be a problem for your structure. Quote Link to comment Share on other sites More sharing options...
olien Posted October 22, 2009 Author Report Share Posted October 22, 2009 Well, I'm not saying the opening structure is perfect, but it is the same one used by ekeblad, granovetter, and rubin, so I'm not going to question its effectiveness too much. They use the 2N opening as natural, but we prefer not to and we have adjusted the system appropriately. A 1D opening is either 5/4+ either way in the minors, 3- suited 4+D, 11+-14 bal, or 5+S 4+D. The 2C opening could be hiding a S canape. Quote Link to comment Share on other sites More sharing options...
