The opponents chimed in with black suit bids to contribute to a lively auction. Your 4♥ bid silences them, and ends the auction. West leads the ♣J, covered by the Queen, King, and ruffed in hand. You continue with the ♥A, and the ♥10 (you might as well tempt west to cover!) to the Queen. Your efforts were in vain, as East discards a club to this trick (and West gives you a pitying look). What is your basic plan?

Solution:
The contract can still be made by endplaying West. In order to prepare for the endplay, you need to ruff a club in hand. This will strip West out of clubs. Now you cash your other top heart, and start running diamonds. Whenever West ruffs the trick, he will have only spades left to play, and will have to concede a trick to your ♠K. What if West refuses to ruff any of your diamonds? You would take the first 10 tricks, 5 hearts and 5 diamonds!

This deal is particularly interesting, as the counterintuitive play of ruffing a club, reducing yourself to one fewer trump than West, is a key play.

Analysis:
Bridge Baron's double dummy analysis confirms that the basic idea of ruffing a club, cashing the other top heart and running diamonds was essential to make the contract (unless West shows you his hand, in which case you can run the ♥10!)
Par Contract Analysis:
The par contract on this deal is 4♥
