The International Bridge Press Association (IBPA) has a newsletter that has many interesting deals, such as this one:
East opened 1 ♥ and South overcalled 1♠. West raised to 2♥ and North ended the auction by bidding 4♠.
Because West had raised on three low, he led the 9♥. East won the ace and shifted to a low club, South winning the ace. How would you play the contract?
It's almost 100% that East had the ♦A, so South played this way: He led a spade to the king, ruffed a heart, ruffed a club and ruffed a heart. He continued by ruffing his last club and leading a heart and discarding a low diamond.
Now East was endplayed. He could cash his ♦A, setting up the king or he could present declarer with a ruff and discard -- either way declarer had 10 tricks and claimed his contract.
