GoSeigen has it: Bh2 is the key move. This chess puzzle was set by Peter Orlik who, Wikipedia tells me, is an American mathematician who specialises in topology, algebra and combinatorics. At least I suppose it the same chap. Chess correspondent Leonard Barden reported on the problem and admitted that it took him 20 minutes to find the key move.

Anyone think the scenario is more realistic set up this way? The balance of power is more even with the black pawn close to promotion, but does the puzzle still work the same way? Is it as "elegant"?
