1st Prize, Budapest v Paris, 1938
Helpmate in 3
If it was White to play he could mate immediately. Black has only five possible moves, but finding the solution may not prove so easy. An excellent solver’s problem.
Set 1...Se6 mate. 1.Kc5 Sh1 2.g×h1B e5 3.Bc6 Ba7. The big clue for the solver is the column of pawns on the a-file, which play no part in the set mate and suggest that the black king may move to c5 or b5. The sacrificial role of the knight is well-hidden, as it guards two flight squares in the set mate.
Jacob Hoover: First White facilitates a black pawn promotion by sacrificing a knight, then moves a pawn out of the newly-promoted piece’s path so that the piece can occupy the one square that the white pieces cannot cover.
Guy Meissonnier: 1...Sh1!! What an astonishing move!
