I am trying a different kind of intermediate problem. Here NS bid to 7NT, and as we can see, they have plenty of tricks, more than 13 yet the declarer went down one. The trick here is to "guess the mistake" (GTM) declarer made during the play.

NOTE this is a beginner/intermediate post...so more advanced players, please hide your responses.

Scoring: IMP

West North East South

 Pass  1    Pass  4NT
 Pass  5    Pass  5NT
 Pass  6    Pass  7NT
 Pass  Pass  Pass  



Trick one.. D6 D8 D9 DK

Declarer played East's hearts to be QT on seeing the T drop on the A?

A reasonable assumption, but no... declarer did not play Ace-King of hearts...

most of the times b/i players do not count so here maybe play ace then finesse one time and then play the king.
happend to me a lot of times.
It's not what you are, it's how you say it!

to make 13 trx you need good things to happen in spades and diamonds and you need to play hearts correctly

I assume as beg int we are not looking for squeezes or fancy discovery plays?

they have 7 hcp where are they

so I think you need to win QD and then play to AK D

we now know D split 1 / 6 and 1 hcp is with east (6 to go)

now we can test Spades

KQS shows W/E have 2/2 so we dont know about 5 of easts card s in the dist

also we need to count the west discard if it was a spade we have 4 spade trx we do not have 4 Diamond tricks


play K the AC east has a D control we cant do anything about yet and we know he is 2C6D2S unknown H and not sure how many C he has


then play from hand to AS and that should give you the picture you need to finsese the hearts the right way

at least I hope that is how to do it

I think they started to play the spade suit badly to start with

The big mistake, as usually is the case, came at trick 1. The hand can be made even assuming some of the "mistakes" noted.

The key play is to win the Q of diamonds, unblocking the suit. Now, even if you do try the spades and pitch a heart, you can cash the rest of the diamonds and play Ace of hearts and heart to the J and then heart king.

The diamonds squeeze west in clubs/hearts, so he has to toss two clubs.
The hearts squeeze east in diamonds/clubs.

As long as South doesn't pitch an "idle club", he can still make on a double squeeze after having cashed the spades and pitched a heart.
