Sharif had to time his four-heart contract carefully. West led the king, ace and another club, the third round won by declarer's queen. If Sharif now led trumps, West would go up with the ace and lead his last club. Declarer would have to ruff in dummy to prevent East from scoring a trump trick, and West's queen of trumps would be promoted into the setting trick. So Omar first played three rounds of diamonds, discarding his last club.
Now he was ready to draw trumps, and it was tempting to come back to his hand with the spade ace to lead the jack of hearts through. That could have been fatal. West could step up with the heart ace and lead his last spade, leaving declarer to guess whether to re-enter his hand by ruffing a spade or dummy's last diamond.
Sharif made the guess unnecessary. He cashed the spade king before leading to the ace. When West took his heart ace he would have to return a suit that would enable Omar to ruff in his hand and lead another heart to pick up the queen and his contract.
Omar says of Sophia Loren's poker-playing that she hates to lose. The same is true of Omar's bridge. Winning eight of his 10 matches in this country has encouraged him to come back for an even longer tour in 1969. The presentation may be somewhat different, but the object the same—beat the circus. With Omar and his All-Stars in top form, that's going to be hard to do.
