  South is to play 4. West leads the K.

Losers:   ♠ = 2    = 1 or 2    = 0   ♣ = 0   Total = 3 or 4

In fact if trumps split 5-0 you could have 3 losers in the suit and a disaster. So we won't worry about that possibility. Since the most likely scenario is a 3-2 split you should plan on taking the A K, then driving out their master trump so you can run dummy's ♣s without somebody ruffing in.

Bad news. West discards a on the second lead.
Time for a change in plans?

Actually, no. East has 2 master trumps at this point but you still have 9 7 5 3. So use one of your little ones to drive out East's J. He will probably force you to ruff a , leaving you with 9 7. Use one of them to force out East's Q. You still have a trump left to stop their s, and as soon as you get the lead you can now run dummy's ♣ suit safely.

  Suppose you had not driven out both of East's high trumps.

He would have ruffed the third ♣, before you could discard a ♠ loser from your hand. You would lose two trumps and two ♠s.
