South ruffed the second heart and drew trump with the top spades. He ran the diamonds but still had to lose two club tricks, N-S +170.
The layout was friendly with spades dividing 2-2 so the defense could not prevent declarer from scoring ten tricks.
North's double raise was weak and South, therefore, entertained no notion of an advance to the major suit game.
Some West players might have entered the auction with a takeout double despite the adverse vulnerability, holding a probably worthless queen of spades. North would again venture three spades as a preemptive action but East would then advance to four hearts. This call would likely be passed out but the display of the dummy would be a huge disappointment. South would cash two spades. North should contribute the jack of spades on the second one to suggest a diamond switch. The defense would swiftly cash two diamonds to earn a one-trick set (+100). There is a very small chance that East could bring home ten tricks when South exits with a trump. He could win four club tricks by playing South for the jack and ten.
A penalty double of four hearts would yield a matchpoint top (+200) but it is highly unlikely that either player would find a double.
