easy Posted December 21, 2004 Report Share Posted December 21, 2004 Hi all I was at a local bridge party last weekend where i heard a discussion re: XYZ convention.... From what i understood the convention is similar to 2way check back. for example 1d 1h1s 2c = relay to clubs 2d = artificial and game forcing. I'd like to know more about this convention. Also how does this convention mesh with fourth suit forcing. A reference to material on the web would be helpful. Thx Easy Quote Link to comment Share on other sites More sharing options...
mikestar Posted December 21, 2004 Report Share Posted December 21, 2004 XYZ is so called because it applies in all auctions that satrt 1X-1Y-1Z. It is an extension of 2 way checkback differing in that 1Z need not be 1NT. XYZ relpaces fourth suit forcing in 1 level sequences. 2C requires opnener to bid 2D. Responer wishes to sign off in diamonds or will show a game invitation. Opener can make a different bid if he would not have passed a natural 2D signoff. 2D is an artificial game force. Lets' take 1D-1H-1S as an example: After 1D-1H-1S-2C-2D, responder bids: Pass= to play.2H = invitational, 5+ hearts2S = invitational, 4 spades2N = invitational, club stopper, tends to be off-shape.3C = invitational, real club suit.3D = invitational, 4+ diamonds Repsponder's rebids other than 2C/2D: 2H=weak signoff, maybe only 5 hearts.2S=weak signoff, 4 spades (sometimes 3)2N=invitational, balanced with with club stopper.3C= club signoff (weak 4-6)3D = GF, excellent diamond support3H = GF, excellent 6+ hearts3S = GF, 4 good spades3N = to play. Direct game forces thend to have very good suits but minimum values. Strong GF hands or hands where the partnership needs to find a fit go thru 2D. Some advanced players prefer conventioal meanings for the GF bids and show all natural GF hand by bidding 2D first. Quote Link to comment Share on other sites More sharing options...
luke warm Posted December 21, 2004 Report Share Posted December 21, 2004 mike's 3 bids are the way i like to play, but i know some who play 1x/1y/1z/3c as a game force also Quote Link to comment Share on other sites More sharing options...
easy Posted December 21, 2004 Author Report Share Posted December 21, 2004 mike Thanks for the information. This convention sounds as if it is most useful when playing secondary jumps are forcing to game. Is that correct? fred (easy) Quote Link to comment Share on other sites More sharing options...
pclayton Posted December 21, 2004 Report Share Posted December 21, 2004 Aside from being GF, they tend to show real good suits (else just bid 2♦). I can't think of another use for a secondary jump frankly in an xyz context (even 3♣). Quote Link to comment Share on other sites More sharing options...
arrows Posted December 29, 2004 Report Share Posted December 29, 2004 This convention sounds as if it is most useful when playing secondary jumps are forcing to game. Is that correct? Should be the other way around: This convention is most useful BECAUSE you can play secondary jump forgame forcing and have many other "free" sequences at your disposal too. For example, with 2♣ starting an invitation sequence, you may reckon that you don't really need 2NT to be natural, let's say you may play 2NT as transfer to 3♣ and thus generate many useful sequences thereafter.....
