Learn How to Deflect the King: Mate in 2
This chess endgame is a classic example of deflection: one forcing move lures the enemy king onto a square where a rook can deliver mate. In practical classical chess, these short tactical finishes often appear when rooks are active, kings are exposed, and the board is stripped down to only a few pieces. Even if you are materially ahead, you still need to watch for mating nets around your own king and look for forcing checks first.
