Black to Play
Published in Chess Puzzles
There’s not much on the board, but a lot is happening. At Goteborg in 1955, GM Arthur Bisguier, Black, to play, is a rook and knight up, but his opponent, Boris Spassky, who would become world champion in 1969, is about to get a queen and make things interesting. Bisguier found a way achieve victory here. What was it?
Solution:
Spassky resigned after he realized that Bisguier’s next move mated him in every variation. Bisguier played 1...Kf5 and that was it. For example: 2.h8=N [2.h8=Q Rg6+ 3.Kh5 (3.Kh7 Ng5#) 3...Nf4+ 4.Kh4 Rg4#]2...Rg7 3.Ng6 Rxg6+ 4.Kh7 Rf6 5.Kh8 Kg6 6.Kg8 Rf8#
