The Box
Part of the Basic Mates section of Coddy's Endgames journey. Lesson 6 of 26.
A queen on her own cannot mate a king, but she can build a box: her rank, her file and her diagonals are walls he cannot cross. Stand her a knight's move from his king, where he can never touch her, and each time he moves, move her to shrink the box. No checks - checks let him out.
