I think that its worth bidding the slam. So far, this seems like the hardest hand... Quote Link to comment Share on other sites More sharing options...

awm Posted July 28, 2013 Report Share Posted July 28, 2013 ... 3♦ (shape)3♥ - 4♣ (relay for QP, 8)4♦ - 4♠ (relay, one stop spade, 0 or 2 top diamonds) Can't be zero diamonds, so Axxxx x AKxx xxx or Axxxx x AQxx Qxx or Axxxx K KQxx xxx. All decent slams but no good grands here. 6♠ - Pass Quote Link to comment Share on other sites More sharing options...

sieong Posted July 28, 2013 Report Share Posted July 28, 2013 3♥ - 4♣ (QP? - 8QP)4♦ - 5♣ (control parity - odd, odd KQJ in ♠, odd KQJ in ♦, even in ♣) At this point, responder possible hands are: AJxxx j AKxx xxx, AJxxx K AJxx xxx. The first hand with HJ plays better in 6NT. The second one plays better in 6NT except on D lead, in which case it makes when HJ falls in 3 rounds (36%) or C finesse (50%) with multiple squeeze chances after a diamond lead is ducked. I rate it to make about 73% on best lead (68% + 5% squeeze chances). I think 6S is slightly better (makes on 4-3, 5-2 the right direction, and 6-1, but some of the 4-3 / 5-2 requires guessing whether to ruff high), probably around 80%. Since I won't be able to distinguish between AJxxx J AKxx xxx and AJxxx K AJxx xxx, I will go with 6NT when that happens. 5♦ - 5♠ (PCB - odd in ♥, no ♠T?)6NT Quote Link to comment Share on other sites More sharing options...
Free Posted July 29, 2013 Report Share Posted July 29, 2013 ...-3♦ (shape)3♥-4♣ (QP ask ; 8)4♦-4NT (start scanning ; 1/2 top honors ♠ and ♦, 0/3 in ♣)6♠-pass (we know Axxxx-?-AKxx-xxx, but impossible to know about ♥K) Again it would be useful to know about a singleton top honor. With ♥K we can play grand, I wonder how we can find out about this. Quote Link to comment Share on other sites More sharing options...

With ♥K we can play grand, I wonder how we can find out about this. PCB bidders were able to rule out the stiff K♥ in this particular case.
