As a player on the Lara team found out, you better be careful when you double Doron Yadlin. This deal from the quarterfinal match of the Kalish and Lara squads is a case in point.

The contract cannot be defeated, but declarer must take care in the play, which is exactly what Doron did.
The opening lead was the ¨J, Rusinow style. Doron won with the ace and played the ªK from hand. East won the ace as West signaled a count of four cards. The ¨9 was next, taken by North with the king. Then came the §A, a spade to the queen and the §Q, ducked. Doron discarded his ªJ on the §Q then ruffed a club low. He ruffed a diamond in dummy, ruffed a club with the ©9, which was overruffed by East’s 10. A fourth round of diamonds was ruffed in dummy, leaving this position:

	ª --- © A 8 5 ¨ --- § ---
ª 9 © 6 ¨ --- § K		ª --- © K Q 2 ¨ --- § ---
	ª --- © J ¨ --- § J 8

The ©J ran to East's queen and he was left on play at trick 12 to lead into North's tenace. That was plus 590 for Doron. His team won the match 124-49.
