Last week we offered you the chance to solve a mate in two composed by Surbiton Grandmaster John Rice (solution below).

The January 2019 British Chess Magazine also published a simple helpmate by the same composer.

If you’ve never solved a helpmate before, now’s your chance. This is a helpmate in 4 moves.

In a helpmate, Black plays the first move (unless there’s a half-move stipulation) and both sides cooperate to reach a position where White delivers checkmate.
