And Bobby Wolff says...

When the defenders adopt an unusual approach, don’t assume that they’ve got their eyes closed. It’s an odds-on bet that they do not have your best interests in mind. East takes his spade ace, leaving no doubt that West led a singleton. Nevertheless, East returns the diamond deuce. What should South be thinking about? If he fails to realize what East is up to, he will go down in a cold contract. Why is East delaying the spade ruff? Easy – after he wins the heart ace and gives West a spade ruff, West will return a diamond for East to ruff. Down One. South should neutralize the defense by cashing three rounds of clubs, pitching his good spade king. When he knocks out the trump ace, he wins the return and draw trumps — making an overtrick rather than going down one.

Below is the entire hand.

Bridge is an easy game!
