han Posted March 29, 2008 Report Share Posted March 29, 2008 What is 4NT in this auction: 1D - 1S2C - 2H*3H - 4NT 2H was fourth suit, forcing to game. It seems to me that both keycards for hearts and quantitative are reasonable options and neither can be bid any other way. Quote Link to comment Share on other sites More sharing options...
jdonn Posted March 29, 2008 Report Share Posted March 29, 2008 I think it's quantitative and 5♥ is the only (vague) slam try for hearts. Sad I know.... at least that gives you a way to move toward slam without actually bidding it in both strains, and follows my general principles too in that we haven't agreed a suit and aren't under pressure by the opponents, so 4NT is natural if it can be. I understand that >99% of bridge players would take it as keycard, I am saying what I think it should be though. Quote Link to comment Share on other sites More sharing options...
Guest Jlall Posted March 29, 2008 Report Share Posted March 29, 2008 I'm sure all of my regular partners would take this as natural. This is a very good auction for 4C/4D/RKC which should be standard in spots like this imo. Quote Link to comment Share on other sites More sharing options...
kenrexford Posted March 29, 2008 Report Share Posted March 29, 2008 IMO: 3♠ = natural3NT = natural4minor = fit (RKCB if agreed)4NT = quantitative Heart cannot be "agreed" for slam purposes, IMO. With that hand, Responder would have bid 3♥ instead of 2♥ (5-5, GF). Quote Link to comment Share on other sites More sharing options...
jdonn Posted March 29, 2008 Report Share Posted March 29, 2008 Justin has the artificial structure and Ken plays everything totally natural. :ph34r: Quote Link to comment Share on other sites More sharing options...
Winstonm Posted March 29, 2008 Report Share Posted March 29, 2008 It's dumb to treat this as quantitative when no one has much of a clearly-defined range. This may be a simple case where knowing if enough aces are held is the key to slam. No suit agreed; now quantitative ranges established - gee, what a rarity - 4NT as Blackwood.

helene_t Posted March 29, 2008 Report Share Posted March 29, 2008 No suit agreed so it's quantitative. P's shape is well-defined. Quote Link to comment Share on other sites More sharing options...
nige1 Posted March 29, 2008 Report Share Posted March 29, 2008 What is 4NT in this auction:1♦ - 1♠2♣ - 2♥*3♥ - 4NT2H was fourth suit, forcing to game. It seems to me that both keycards for hearts and quantitative are reasonable options and neither can be bid any other way. I've no idea, but I like the suggestions of JLall and KenRexford. To make a quantitative try, perhaps you could bid a (forcing) 3♠ first. Then - 4♣ = RKCB for ♣ - 4♦ = RKCB for ♦ - 4N = RKCB for ♥ - 3♠ then 4N = Quantitative. I assume that, unless opener has extra values his shape is 0454. With a normal 1444, I assume that he would rebid 1N over 1♠. What is American practice? With my assumption, 3♠ becomes what the Sharples termed an Impulse bid - unable to limit the hand. Rather like 4th suit forcing. Quote Link to comment Share on other sites More sharing options...
han Posted March 29, 2008 Author Report Share Posted March 29, 2008 I wasn't sure how partner would take 4NT so I indeed took the 3S - 4NT route. Quote Link to comment Share on other sites More sharing options...

With my assumption, 3♠ becomes what the Sharples termed an Impulse bid - unable to limit the hand. Rather like 4th suit forcing. I'm not sure that this is a good sequence for 4minor as RKCB. That seems to put a lot of pressure on Responder to buy or sell. IMO, the minor calls should be simply natural, perhaps with the next-up (Kickback?) as RKCB by Opener (or anything else hedgy cues), or two-up as RKCB, allowing Opener to "hedgy cue" a LTTC bid below the ask. The latter would be my preference, personally. (4♣ agrees clubs, 4♥ is RKCB, Opener can bid 4♦ over 4♣ as LT. 4♦ agrees diamonds, 4♠ is RKCB, Opener can bid 4♥ over 4♦ as LT. Anyone can cue past (instead of) RKCB as a mild bump/Q.) Is that artificial enough, Josh? LOL Quote Link to comment Share on other sites More sharing options...

helene_t Posted March 29, 2008 Report Share Posted March 29, 2008 I this auction opener's shape is almost completely known while nothing is know about responder other than 4+ spades. So what about 3♠ as a relay? Quote Link to comment Share on other sites More sharing options...

jdonn Posted March 30, 2008 Report Share Posted March 30, 2008 Well it's not perfect since you lose 3 steps to agree either minor. But I have to admit the plusses seem to outweigh that, probably. Quote Link to comment Share on other sites More sharing options...
