  You have 11 winners; 1 ♠, 2 s, 4 s and 4 ♣s. If you can make a trick with the ♠J all will be well. But if not, as long as West holds the ♠Q, which is almost a certainty, you will be able to squeeze him in ♠s and s.

The first thing you should do is to duck the ♠K. If West foolishly plays another ♠ your troubles are over. But he doesn't, he plays the Q instead which you win with dummy's K.

  Even though West didn't play a second ♠ your first round duck served a very important purpose - it rectified the count for your squeeze.

Next play off your 4 winners, discarding a small from your hand.

  You are now zeroing in on West.

Play the ♣K, ♣J, then over to your ♣Q.

  Here is the layout after the 3 ♣ plays. Everybody followed suit except West who discarded a (unhappily, it seemed).

When you now play your ♣A, discarding a ♠ from dummy, West is squeezed.

If he discards the ♠10, then his ♠Q will fall underneath your ♠A, establishing your ♠J.

But if he instead throws the 9, both of dummy's s will become winners.
