Last week we left you by this endgame study composed by RTCC and former RJCC star Caspar Bates.

Here’s the solution:

The natural move 1. bxa8Q only leads to a draw so:

1. a7 c1Q
2. axb8Q Kh7

Threatening Qh6#: it seems like White has no good checks, but…

3. Qh8+ Kxh8
4. Kg6

Black cannot avoid checkmate.

This week’s puzzle was something GM Bogdan Lalic posted on his Facebook page recently. Choose a move for Black.
