geofspa Posted March 2, 2011 Report Share Posted March 2, 2011 Hi The other day this bidding sequence came up and my partner gave it one treatment and I another. (Unopposed bidding) 1NT(15-17) - 2♣ 2♠ - 4NT I don't know that hands this strong occur together too often so we had not discussed this sequence. My question is about the 4NT bid which I think should be quantative as there are forcing bids available with a fit although my partner thinks it is fit showing and should be Blackwood (of whichever flavour you have earlier agreed) Please discuss Geof Quote Link to comment Share on other sites More sharing options...
mtvesuvius Posted March 2, 2011 Report Share Posted March 2, 2011 "Standard" would be quantitative. Quantitative without a fit is better because either you can use 4♣ as 1430 Gerber, or use some form of Baze, where 3 of the other major is a forcing raise with Shortness, 4♣ is Quantitative with a fit, and 4♦ is Keycard (you can reverse the 4m calls if you wish, I prefer this method though).

TWO4BRIDGE Posted March 2, 2011 Report Share Posted March 2, 2011 Here is my reply ( # 8 ) to jillybean's similar thread ( http://www.bridgebase.com/forums/topic/43208-an-auction/ ) last December: One popular structure : 1NT - 2C2S - ?? 3H! = fit, shortness somewhere; next step (3S!) asks4D! = fit, no shortness, artificial slamtry 4C! = fit, RKC Gerber for Sp 3C/3D = no fit, longer minor suit4NT = no fit, quantitative Quote Link to comment Share on other sites More sharing options...
ggwhiz Posted March 2, 2011 Report Share Posted March 2, 2011 Quantitative here and the suggested structures are good. Just for ease of memory, we only play the 3 of the unbid major as a general slam try portion to turn a future 4nt bid into blackwood. If you proceed over 4nt, how? We respond RKC with interest and on the more standard 1nt - 4nt, respond straight Aces followed by 4-card suits up the line from there, stopping in a 4-4 fit if we find one or 6nt. 5nt after a response to 4nt would be to play.
