Just for a change from Daoists, Mahler, and Turkish culture, here’s a delightful bridge challenge!
As you see in my note to Perfection is NOT the word for it, my skills on the baize are rudimentary, having been only modestly maintained on orchestral tours on the back of a bus, suitably lubricated by alcohol. By now I’m even more out of practice than usual, but among a wealth of such problems I find this one particularly charming. Like the abstract beauty of dhrupad, it’s an infinite world.
I can’t see the solution online, but after the opening spade lead from West (almost inevitable, one would think, though it’s the only lead that makes the grand slam possible!) all thirteen tricks must be won in dummy—to which end, declarer must first discard the ❤️A and K on the two opening spade tricks, and then discard all the top diamonds on dummy’s four heart tricks!
Wonderful, eh—pour me another gin…
