Solution

North goes up with the K and leads a diamond for South to finesse and win two trump tricks.  Now a low heart is led and West wins with the Q.  West does best now to lead a low club to the 10, Q, and A.  The next three tricks are taken by the 10, the Q and the A on which North throws a club. This is now the position, with East still to discard:

♠ KJ32

♣ none

♠ 54

 9

♣ K6

♠ A109

♣ 987

♠ Q

 none

 7

♣ 432

A.      If East discards a spade, North overtakes the Q to establish the suit with a ruff as entry.

B.      If East discards a club, the Q is allowed to hold and South then leads a club.

1.       If West rises with the K, North ruffs and leads a high spade.  South ruffs the A and puts East in with a club so that North’s spade winner takes the last trick.

2.       If West plays low, North discards a spade and East is endplayed.  Whichever black suit winner comes next is ruffed and then the hand opposite takes the last two tricks with a ruff and a black suit winner.

This problem is based on Ernest Pawle's last problem to appear in Bridge Magazine, as No. 184, July 1966, before his untimely death that year.  Here is the problem as it appeared in that issue

♠ KJ95

♠ Q

 AKQ7

♣ A432

South to make five diamonds.  West leads  a low heart.

The solution given was as essentially shown above but alas a much easier solution turned out to be available, thanks to North's 9.  North wins the opening lead and after three rounds of trumps South leads the Q.  East lets this win but after the A and another club, North can ruff the third club and lead a high spade, covered by East and ruffed.  East is thron in on the fourth club to lead into North's spade tenace.

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