Checkmates From Hou Yifan Games Puzzle: Mate — Rook Deflection

This chess endgame demonstrates how forcing rook checks can overcome a serious material deficit. Black has extra pawns and active pieces, but the king’s shelter creates a tactical weakness. The key idea is to make the defending rook respond to check, then exploit its forced placement. This is a classic back rank mate pattern: a rook controls the escape squares along the back rank while the king’s own pawns limit its mobility. In such positions, initiative matters more than material count.
