CHECKMATE!
(
The Guarded Chessboard)
Strolling into one of the rooms of a London club, I noticed a position
left by two players who had gone. This position is shown in the diagram.
It is evident that White has checkmated Black. But how did he do it?
That is the puzzle.
Answer:
Remove the White pawn from B 6th to K 4th and place a Black pawn on
Black's KB 2nd. Now, White plays P to K 5th, check, and Black must play
P to B 4th. Then White plays P takes P _en passant_, checkmate. This was
therefore White's last move, and leaves the position given. It is the
only possible solution.
