Solution

A.      If West leads the ♣K,  North wins and leads the K to South's A and then ruffs the Q!  North leads a low spade and when East plays low South discards the 4 to throw West in for either a ruff and discard or a heart lead into the tenace.

B.      If West leads the ♠10,  South ruffs high and leads a high club to North's ♣A.  A second spade is ruffed high and North's K and a club are entries for two further spade ruffs high.  South then cashes the A and leads a club in this position:

 ♠ none ♥ 873 ♦ none ♣ 72 ♠ none ♥ KJ105 ♦ 10 ♣ none ♠ 76 ♥ 96 ♦ J ♣ none ♠ none ♥ AQ4 ♦ none ♣ 64

(Alternatively, South could have ♣43 opposite North's ♣52.)  Now, if West discards

1.       the 10, then North plays low and wins the next club, on which West is one-suit squeezed.  West does best to discard a middle heart but then the 8 is covered around the table and West has to lead into a split tenace.

2.      the 5, then an immediate exit on a low heart endplays West for a heart lead or a ruff and discard.

3.      the 10, then North overtakes the club and leads the 8, covered around the table.  Again West is endplayed.
