Last week’s puzzle was a mate in 2 by Fritz Giegold, taken from Rewire your Chess Brain by Cyrus Lakdawala (read my review here).

The solution is 1. Ne6 Kxe6 2. Qe5#: a triple pin mate.

Other variations: 1… Bxb2 2. Bb7#, 1… Nxb6 2. Qg2#, 1… Nf8 2. Qxb3#, 1… Nc7 2. Rd6#, 1… Nc5 2. Nf4#, 1… Ne5 2. Qd4#.

The problem also features a knight wheel. Any of White’s eight knight moves will threaten Bb7#, but Ne6 is the only one that forces the required mate in 2 moves.
