Dear Shelby Lyman, you missed Mate in One:

Shelby Lyman’s May 5, 2013 Sunday Chess column has “White to Play” for this problem:

White(5): Rg8, Bh5, Nd3, Kg3, g4

Black(5): Rh7, Bd7, Nc6, Kh6, c7 .

His solution is mate in two: 1. g5ch, Kxh5; 2. Nf4 mate.

Most of us would prefer the simpler: Rg6 mate.

Shelby! Check your problems!!!!

Thanks.
