  At first glance this doesn't appear to be a difficult hand. You expect to win the opening lead, pull trumps, then establish a winner by playing K, A, and ruffing a . As long as they split 3-2 you could reach dummy's winner with the K.

So you take the ♠A, pull three rounds of trumps and play K.

But when you lead to the A West discards a small ♠.

  Time to rethink. You are in dummy now, and you can ruff a , return with the K and ruff another . The last would be good but you'd have no way to reach it.

Think squeeze instead. Ruff a . This turns the J into a Threat card against East's Q.

But, the ♠J is already a Threat card against West's ♠Q.

  Play your ♣J and ♣9, discarding the 8 and the 4 from dummy.

West can afford to discard the ♠9 and the 5.

East can spare his two ♠s.

  You are there. Play your ♣8.

West cannot throw the ♠Q, so he gives up the 8.
Dummy's ♠J is of no further value so you dump it.

East cannot throw the Q, so he gives up the 2.

And you take the last three tricks with the suit. There were only two defenders; one of them had to guard ♠s and the other had to guard s. There was nobody left to guard s.
