Chamaco Posted December 9, 2003 Report Share Posted December 9, 2003 Hi all,I am starting to play Multi 2D, including weak 2 in a major, strong balanced hands AND strong 4441.I know there are other styles of playing 2D Multi, but this is the one I chose. :) So I would like to know where I can find material on how to deal with opps interventions, especially if they are at the 3 level, with special attention to 2D-3C-pass-pass- ?2D-3D-pass-pass- ?2D-3H-pass-pass- ?2D-3S-pass-pass- ? Thanks a lot !! Mauro Quote Link to comment Share on other sites More sharing options...
Free Posted December 9, 2003 Report Share Posted December 9, 2003 The normal way of bidding when showing multi hands, is this: "When weak, shut up unless you have to bid, you've done your job". So with all these above hands, you pass with a weak hand, and bid on with a strong hand (partner passed, so he's not strong or has a penalty pass). If they bid your suit or if you have a NT-hand with good trumps, you Dbl, otherwise you bid the next step (if you have 4441 with stiff in their suit) or pass (when weak-2). There are some other interventions which might be interesting for you:2D-p-2NT-3C-?2D-p-2NT-3D-?2D-p-2NT-3H-?2D-p-2NT-3S-?Here it seems we can play at 3-level without problems, so you'll always bid. after 2D-p-2NT-3m-?Pass = maximum with HDbl = maximum with S3M = minimum with Mother bids are strong versions after 2D-p-2NT-3M-?Pass = other majorDbl = penalty, weak-2Mother bids are strong versions This can still be improved, but its very easy to remember.

inquiry Posted December 9, 2003 Report Share Posted December 9, 2003 Thanks a lot !! Hi Mauro 2D-3C-pass-pass- ?2D-3D-pass-pass- ?2D-3H-pass-pass- ?2D-3S-pass-pass- ? The problem you have is that I think your version of multi 2D is unplayable. I tried it too, but soon switched to a version where 2D is the weak two in the major, the big balanced hand, or an ACOL 2 bid in a minor (good suit, 9.5 tricks). Playing this way, dbl of all these hands shows the strong the NOTRUMP hand, and bidding the minor at the 4 level shows the acol 2 bid. With the weak two, I just pass, or if feeling lucky, bid my major at the three level. Your way, if you have the balanced hand and no stopper you are somewhat stuck. Would a double show the three suiter? What if they bid one of your four card suits? Anyway, since you are just getting started on this system, why not take a look at the Multi-2D method as written up by Dr. Chris Rydal, and then look at his 2C structure (if you play 2C as strong, instead of polish club or some other forcing club system). He includes the 4441 hands in his 2C structure. His webpage describiing his multi 2D (which also has a link to his 2C page) is... http://www.cavendish.demon.co.uk/bridge/tw...wo/diamonds.htm Quote Link to comment Share on other sites More sharing options...
mishovnbg Posted December 9, 2003 Report Share Posted December 9, 2003 Hi Mauro! Best way to play multi bids in my opinion is when all variants include same or similar distribution, strong or weak. Same way give your partner opportunity to participate after opponents intervention and his bids are usefull for you, strong or weak. For example in Rumen-Kalin system (best bulgarian pair) 2DI include weak 2 major or strong major 2 suiter. If your opening include minors or 3 suited hand or blanced hand, your partner bids at 4 level can be very dangerous and you can lose simple 3NT contract.

B) The idea of playing Multi 2D as weak 2, big balanced OR strong 4441 is to include it in a Precision framework.22-23 bal wd be shown by 1C and NT jump rebid. I was planning to show 20-21 in the multi2D -I need a strong 4441 opening (without weird sequences :;) after 1C opening to show it). -2H is 11-15 3-suiter short in diamonds-AND I need 2S and 2NT as a preemptive opening as well as 3-level (Bergen "2-under" xfer preempts in 1st and 2nd seat). any comments ? :) Quote Link to comment Share on other sites More sharing options...
Free Posted December 10, 2003 Report Share Posted December 10, 2003 I'd turn that around, because in case of 22-23 2NT won't be a big problem if partner has 0 HCP, but if you play 2NT with 20 HCP in one hand you'll have trouble! I'd play 22-23 in the multi, and open 1C with 20-21 so you can still play 1NT... Free Quote Link to comment Share on other sites More sharing options...

Ty Misho.Here is the sequence i use for 3 suiters inuncontested auctions: In uncontested sequence, they are shown:- over 2H/2S (seminegatives), bidding the suit below the singleton; p can ask range of 3 suiter by bidding the singleton- over 2NT (positive, asking):a) 3C : GOOD weak 2 in H OR 4441 16-19 black singleton.3D asks, and 3H = weak 2 in H, 3S= singltn clubs, 3NT = sngltn spadesB) 3D : GOOD weak 2 in S OR 4441 16-19 red singleton.3H asks, and 3S = weak 2 in S, 3NT= singltn diam, 4C= sngltn heartsc) 3H/S = bad weak 2, naturald) 3NT = big balanced e) 4CDHS = max 4441 (20-24), singleton in next suit. All bids are then signoff (including 4NT) except bidding the singleton, which asks controls Quote Link to comment Share on other sites More sharing options...

Free-------------------------------------------------- That is true, but I believe that:1) Multi is less effective as a preempt than natural preempts (pard cannot raise immediately the preempt, since he does not know ur hand), so opps that do not fear overcalling at 1st round will describe their hands easier2) for this, I want to include strong hands that occur more frequently. Otherwise, I get only the disadvantage of Multi. 22-23 is a very rare beast, 20-21 not so rare, and well suited for penalizing.3) after all, 20-21 is the range by which 2/1 players open, so, if pard is broke, tough luck B)2) to compensate for this u need to penalize opps that interfere Quote Link to comment Share on other sites More sharing options...

If he has an invitational hand and you're strong, there wont be a problem. Partner can still bid 2S, 3H, 3S, 4H to let partner descide...2) if you want to include strong hands which occur frequently, dont use 4441s, because they are not so frequent as you think. Ok, 20-21 is more frequent, but it takes you too high imo3) its not because another system uses an opening which isn't the greatest, that you need to do the same when you don't have to! I'm not saying that 20-21 2NT-opening is bad, but it has its negative sides, and if you don't need to take the disadvantages of this opening, why would you?4) how many times can you penalize ops? If you have 20-21HCP or even 22-23, ops wont intervene that many times... A multi-opening isn't the same as a strong 1C opening where ops intervene about always B) If you have a strong hand, and they bid 2M or 3m, they have a lot of chances of making it when having about 20HCP together.

mishovnbg Posted December 10, 2003 Report Share Posted December 10, 2003 Hi Mauro! 1. You can lose some direct preempt playing multi 2DI, but only if fit is not sure. You win dutch 2HE/SP 5M-4m, more often come and better for pre-empts than 1 suited 2HE/SP. 2. Any way you will lose in competition with strong hand if final contract must be 3NT, but your partner already bid at 4 level or he passed and you must describe your hand at 4 level. Examples: NAxxxxxxxxxxxx S x Kxx Ax Ax AKQJxxx AKQx KJx KQJx S W N E2DI(multi) (2SP) 4HE( B)) p? ... Missed 3NT contract ! Misho Quote Link to comment Share on other sites More sharing options...

Misho This is why I play 2D-P-3NT as the preemptive raise in both majors (partner bid your major at the four level) rather than as 4H as P/C.... I use the responder jump to 4C to show 5H and 4S, the jump to 4D to show 5S and 4H, and I bid 4H and 4S to play based upon MY HAND... (novel concept, bidding your own suit..hehehe...

mishovnbg Posted December 10, 2003 Report Share Posted December 10, 2003 Hi Ben! May be in competition your 3NT also show stopper in opp suit, not only both majors fit ;D? Misho Quote Link to comment Share on other sites More sharing options...
