Solution

The defence must play on hearts, West starting with a low one.  Declarer's best try is to let East's Q win the first trick and play low on the return, but West plays the K anyway, to be sure of removing North's heart entry before diamonds are established.  North wins the second heart and now does best to lead a high diamond.  However, West ducks (!), wins the diamond continuation and leads a club, covered around the table to South's A.  Declarer's last-ditch effort now is to cash the Q, but East is careful to drop the 6, retaining the 2 as a guaranteed exit card.

Trap: If West exits on a heart instead of a club at trick 5, South wins and leads the 10, followed by the 6 when the 10 is allowed to hold.  East wins the second spade and returns a third, but North discards the heart loser and South can play either the Q or A and a low one.

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