Weekly Hand Analysis - Vic Johnson - January 8, 2024 - Slam

 

Question: 

Was this a biddable slam?

Vic:

Yes, it was a biddable slam. 

 South deserves to take 12 tricks in hearts, so it was also a makeable (small) slam.

 Assuming the 2NT bid by North (Responder) was Jacoby 2NT, Opener has a right to picture Responder with four card heart support & 13+ HCPs. Opener has 16 HCPs, giving the partners a total of at least 29 HCPs. 

 For small slams in NT, 33 HCPs is the common gold standard. By that standard (assuming Responder has the minimum), this hand does not measure up to slam. 

 For small slams in a suit contract, however, distribution features (singletons/voids) & the location of six critical cards often enable slams with fewer than 33 HCPs (sometimes far fewer). The six "critical cards" are the four Aces plus the King & Queen of trump.

 Playing Jacoby 2NT, a second call of 3C by Opener promises a singleton or void in clubs. The correct second call by Opener was 3S. For an experienced pair, I suspect a second call of 3S would have initiated a cue bidding sequence that would have gotten the pair to slam.

 Looks to me like the 3C bid by Opener was an attempt to show a two-suited hand. That is what Opener has, but playing Jacoby 2NT, that is not what they have promised.

 Over 3C, Responder then bid 3H which I would expect Opener to interpret as encouraging (the stronger the hand, the slower the bidding). Opener proceeded to set the contract by bidding 4H. That was an unfortunate choice for more than one reason.

 Opener knows they have a nine card golden fit. Nine card fits are worth 2-3 HCPs more than eight card fits. The spade singleton also makes opener's hand worth more than 16 HCPs. Finally, Opener holds three of the six critical cards mentioned above. If Responder has at least two of the other three, the partners definitely belong in slam.

 Rather than end the auction by bidding 4H, I would encourage Opener to bid 4NT (Blackwood). Responder should subsequently show two Aces. Opener should then set the contract at 6H.

 Ain't bridge a great game?
