smerriman Posted May 28, 2020 Report Share Posted May 28, 2020 Wow, a real-life criss-cross squeeze. Nice hand. Still recoverable after the first two tricks, if you assume GIB won't lead low from 43 (which it doesn't do 98% of the time). 1 Quote Link to comment Share on other sites More sharing options...
Cyberyeti Posted May 28, 2020 Report Share Posted May 28, 2020 Declarer didn't unblock a middle spade under the ace ? and then didn't finesse ? having played low and the ace on the first club ? 1 Quote Link to comment Share on other sites More sharing options...

Cyberyeti Posted May 28, 2020 Report Share Posted May 28, 2020 Not being an expert, can you explain why you would not prefer the safer 7 spade contract? Obviously at IMPs you would prefer to be in 7♠ seeing both hands, but if the spades run, you know that all you need is partner's A to some number of hearts to allow your KQJxx to run to make 13 tricks in NT. It's entirely possible partner's hand is Qxx, A10, xxxx, KQxx where 7♠ requires the spades to break, 7N is laydown. Quote Link to comment Share on other sites More sharing options...

Err it's not clear that's the misclick, as I pointed out in my previous post, there are 3 mistakes in the play that could be that misclick Quote Link to comment Share on other sites More sharing options...

Yes? Lower percent. Pilowsky is right as at imps N/S should be playing 7♠,not 7NT. Quote Link to comment Share on other sites More sharing options...

Pilowsky is right as at imps N/S should be playing 7♠,not 7NT. It's only that bad because partner only has one heart, he could easily have had 3 or 4. As I said earlier, if you could see both hands you want to be in 7♠, partner could easily have bid the same with a hand where 7N is laydown and 7♠ isn't, it's a judgment call. 1 Quote Link to comment Share on other sites More sharing options...

I see what you are saying. North could be 3352 instead of 4162. that 4th ♠ make all difference. Bigger fit. Not easy to show good 4 card support here. 4♥ splinter instead of 3♠? Human bid not robot?

Not easy to show good 4 card support here. 4♥ splinter instead of 3♠? Human bid not robot? More of a worry is the hand I posted above, Qxx, A10(x), xxx(x), KQxx where you have 13 off the top in NT, but need a 3-2 spade break in 7♠, all you know about the hand is the 3 high cards, 3+ spades and no strong 5+ card suit.

Pilowsky is right as at imps N/S should be playing 7♠,not 7NT.Either East or West could be squeezed. The ♦J also has to be in the same hand as ♦K unless one of them is singleton or jack is doubleton. So squeeze is a much lower percentage. Quote Link to comment Share on other sites More sharing options...

South bid 7NT without disclosing ♥ length. Hence, at the table, on a ♣ lead, with normal defence, South has excellent chances. At trick 2, declarer can unblock ♠9 from dummy. Then cash 7 black winners, ending in dummy. Suppose declarer has 2 or more ♦s rather than 5 ♥s. Now, it could be fatal for either defender to reduce to a singleton ♦. Thus, IMO, it's hard for a defender to keep 5 ♥.[/hv] Quote Link to comment Share on other sites More sharing options...
