Chess Puzzle of the Week (39)

puzzle38

Last week Richard Thursby asked you to mate in 3 moves using the bishop on b1. You have to think outside, or perhaps, inside, the box to solve this.

1. Bxf5 gxf5 (now the bishop is back in the box.)
2. b8=B (now the bishop is outside the box again, but on a black square. It must be the bishop that has just been captured as the other one is still on the board.)
2… f4
3. Be5#

The latest issue of The Problemist features an article by David Shire on the problems of  Henry D’Oyly Bernard (1878-1954).

This example shouldn’t detain you long. It was published in the Western Morning News in 1904.

White to play and force mate in 2 moves.
