West switched to the king of clubs for the ace. South continued with a low heart as West hopped with the king and exited with another. South continued with the ten of spades finessing West for the queen and was soon claiming an overtrick, N-S +650. The play was an open book because West was certain to hold the queen of spades and the king of hearts. dbl 4Ɔ North doubled 1NT for penalty but East's redouble was SOS forcing West to rebid two clubs. An immediate two clubs would have functioned as Stayman in search of a major suit fit.
South erroneously assumed that East would correct to two diamonds, a contract which he had no desire to defend especially if doubled. Accordingly, he judged to rebid hearts in search of a major suit fit. North had an easy raise to the major suit game holding five-card heart support, a singleton club and the ace-jack of spades. This was an unusual action given that West had overcalled 1NT but North held a virtual goldmine prompting the leap to game.
Four spades is also icy but play in the nine-card fit is best.
