This deal occurred in a pairs tournament in New Jersey some years ago.  After North-South reached four spades, West, at favourable vulnerability, elected to sacrifice in five diamonds. 

South should probably have passed his partner's double of five diamonds, but he was reluctant to settle for plus 300 or 500 points when he felt there was a good chance to score 650 at five spades.

South regretted his decision as soon as he saw the dummy.  To make the contract he would have to hold his losers to one heart and one club.  This would apparently require a successful diamond finesse (virtually assured by the bidding), a successful spade finesse with East holding two spades, and a 3-2 division of the opposing clubs.

Given West's ominous four-of-clubs lead, which looked like a sure singleton, South did not like his chances, but he plunged ahead bravely and found a way to make the contract.  If you like solving problems of this sort, see if you can figure out how he did it before reading on.                                                                                                             

Declarer took East's eight of clubs with the ace, led a diamond to the queen and returned a spade, finessing the queen after East followed low.  South then cashed the ace of spades and king of clubs, confirming the bad news in the club suit, and led the three of spades to dummy's six.  The ace of diamonds was then cashed, declarer discarding a club and the seven of diamonds was led, but instead of ruffing, South discarded his remaining club!

The sequence of plays left West without recourse.  He had to return a heart - allowing South to score a trick with the king - or a diamond, allowing South to discard a heart as he ruffed in dummy.  Either way, the improbable game was home.
