The bidding was 1S by north, 2H, pass, pass, 2S, pass, 2N, pass, 3C, pass, 3S, pass 4S.

 

The lead was the ace of diamonds, 9 from west (udca).

The ace of hearts was next, 7 from west (udca).

King of diamonds ruffed.

Small spade to the queen and king.

 

Now west must play a heart to beat the contract. However, if north is 7114 this defense would be disastrous. West ended up continuing trumps and the contract made. What went wrong in the defense, and should west have worked this out?

It seems to be double dummy now. North surely has six spades, with seven he would not introduce clubs over 2NT. He has shown up with 1. So he could be 6-1-1-5 or 6-2-1-4. Either way, a heart now kills him. You must score a . If he is 6-1-1-5, he can throw two clubs away, but still at best AKx of clubs remaining. If he is 6-2-1-4, he can throw only one club away (before you can ruff in). And this prevents him later access to the hearts.

 

This isn't even hard, and certainly is not a guess.

At trick two, third hand would not play the 7 of hearts from 87x so he must have a doubleton. The opening leader should read declarer for 6-2-1-4 shape and play another heart at trick three, after which there is no need for guesswork.

Great! Glad someone said this.

 

Here was my thinking. Declarer, on the auction is an overwhelming favorite to have 6214 and not 7114. However, partner knew the heart count and elected to play the diamond king. My partner is a great player, and even though this was a late night BBO match I decided I would have full trust in him. I think his DK was an error.
