The final deal of a Goldstone quarter final match
North's two notrump was a game forcing raise in hearts and four hearts showed a minimum.
You choose to lead a diamond, partner plays the five, declarer wins with the king and runs the jack of hearts to partner's king.
Partner now plays the club king which declarer wins with the ace while you play the four (standard count).
Declarer draws another trump, partner following, then cashes two more diamonds with everybody following and plays a club to partner's queen.
Partner now plays the four of spades, declarer the three. How do you defend?
Scroll down when you have decided.
Declarer's distribution is, unfortunately for him, the same as dummy's.
You must play low on this spade.
If declarer has Qxx in spades he will lose two tricks anyway, if he has K9x of spades then nothing will beat the contract, but if he has Kxx then you have to duck.
The full deal was
If declarer had played the seven of spades instead of the three West's duck would not work as declarer can now cross to table in trumps and lead the spade jack.
East should have exited with the spade nine to ensure the defeat of the contract.
Note that an initial club lead will beat the contract easily on a normal line of play.
