Solution

West does best to start with two top hearts.  On the second, South must discard the A!  If West switches to spades now, North will have two entries, allowing South to take a diamond finesse and later, after playing a low club to North's ♣J, finesse and run the clubs.  West therefore cashes a third heart and leads a spade to North's 10.  South discards the Q on the third heart, finesses the Q, cashes the minor suit aces and exits on a third diamond to West, who now has only spades left.  North makes the K and the two long diamonds, squeezing East between hearts and clubs.

See the solution to Competition Problem #4 for the recommended tabular format if you prefer not to write in English prose.
