There’s approximately one chance in 500,000 of being dealt a hand containing 30 high-card points. And so, anytime you see one in a book or a bridge column, it’s very likely that the hand was composed by somebody, and not actually dealt.
That would certainly be true of this deal, which was published as a doubledummy problem in The Bridge World Magazine in the 1930s to illustrate what was then called a quadruple trump grand coup.
Given East’s holding of the Q-10-7-3 of trumps, making seven spades would seem to be an impossible task. But of course the deed can be done, or the hand would not be presented here. If you would like to test your problem-solving skills first, assume West leads a club, and do not read past this point.
After taking the club king, declarer next leads a heart and trumps it instead of doing what comes much more naturally, which would be to cash the trump ace at trick two. Cashing the ace of trumps would inevitably prove fatal. If you don’t believe it, try playing the ace at once and see what eventually happens.
South next plays a diamond to the queen, ruffs a second heart, then plays a diamond to the king, ruffs a third heart, followed by a diamond to the ace and another heart ruff. This reduces declarer’s hand to five cards — a club and the K-J-9-8 of spades — while dummy has the ace of trumps, a low diamond and the A-4-2 of clubs.
South then leads a club to the ace and returns a club, forcing East to ruff as declarer in turn overruffs. Next comes the nine of spades to the ace, followed by a diamond or a club. East's last two cards, the Q10 of spades, then succumb to the K-J to put the final touch on the extremely rare
-- and in this case, contrived
-- quadruple trump grand coup.
