Chess Puzzle of the Week (68): Solution


Last week I offered you a helpmate in two moves with two solutions composed by Geoff Foster (The Problemist Supplement 2009).

The solutions (Black moving first): 1. h1N Rg8 2. Nf2 Rxg1# and 1. Kf2 Qd3 2. e1B Rxh2#. Each black pawn underpromotes: one to a knight and one to a bishop.
