Solution

This one was contributed by Paolo Treossi.  It had been reported to him by Silvano Nanni, who didn't know its origin, and nor did I until Eugeniusz Paprotny emailed to tell me it appears as Problem 82 in my 1973 book Bridge Magic!  That being the case, it should also have appeared in my main archive here, but it doesnt and I cant explain why.

East cunningly plays a low club but South ruffs with the 2 anyway!  South’s top trumps provide re-entries for two ruffing finesses in spades and a third round of that suit, North discarding the A whenever South’s card wins.  South continues spades until West ruffs, when North plays the J, overruffing or underruffing as appropriate.

A.      If North has overruffed, South comes to hand on a club ruff and continues spades until West ruffs with the Q.  That player then has only hearts left, giving South the remaining tricks.

B.      If North has underruffed, South’s hand is high and wins the remaining tricks regardless of whether West returns a heart or the 5.

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