pescetom Posted September 19, 2019 Report Share Posted September 19, 2019 This hand 21 cost Italy 13 IMPs and a vital win against leaders USA1 in the Bermuda Bowl. A very surprising mishap by a team famed for precise slam bidding - almost any system (even stone age Blackwood and number of Kings) should lead straight to grand here. I can only guess that 4NT was intended by Bocchi as RKCB but Sementa took it as Turbo - in any case not conceivable at this level. Quote Link to comment Share on other sites More sharing options...

But England had their own slam mishap in the earlier rounds missing a 13 trick laydown grand against Indonesia.

sfi Posted September 19, 2019 Report Share Posted September 19, 2019 I don't know what happened here, but it's easier to bid if South asks for key cards. If North asks, South at some point will need to decide they have enough extras for the grand. Missing it does look like an error though.

If North asks, South at some point will need to decide they have enough extras for the grand. Even the weakest players in our Friday night field are capable of: 1♠ 4NT5♥ 5NT 6S 7NT:) We would probably bid:1♠ 2♣2♦ 3♠4♣ 4♥5♦ 6♣6♥ 7♠.South knows the clubs situation and that we have all the keycards. But any decent system should get there I think. Only a few countries failed to call 7♠. Quote Link to comment Share on other sites More sharing options...
sfi Posted September 19, 2019 Report Share Posted September 19, 2019 Well, your weaker players have to find a queen to make 7NT and you have some problems if North doesn't have the DK, assuming I understand your auction correctly. If North is 5251 you may be in a very poor spot. I agree that you should find it, but those auctions have problems. As I said, if South takes control it's obvious to bid. If not, there is a bit more work to do. Quote Link to comment Share on other sites More sharing options...
barmar Posted September 19, 2019 Report Share Posted September 19, 2019 Well, your weaker players have to find a queen to make 7NT and you have some problems if North doesn't have the DK, assuming I understand your auction correctly. It looks like the weaker players are using old fashioned Blackwood, so 6♠ showed 3 kings and all the aces and kings are accounted for. West appears to be triple-squeezed on the run of the spades, but would the weakest player find that? Quote Link to comment Share on other sites More sharing options...
barmar Posted September 19, 2019 Report Share Posted September 19, 2019 In case anyone is curious, we asked GIB how it would bid this. It doesn't find the grand, either. 1♠ - 2N3♣ - 3♥6♠ Quote Link to comment Share on other sites More sharing options...

It will happily bid grand slam in a 4-2 fit after you double then try to show a good one-suiter. B-) ahydra 1 Quote Link to comment Share on other sites More sharing options...
