Queen vs Rook
Win against perfect defense
Setting up the board…
The theory
Queen versus rook is won, and it is the ending where even titled players have burned their fifty moves against perfect defense. The defense is easy to play approximately; the win demands precision.
The defender's setup keeps the rook one knight's-move from its king, pivoting around it. Chase the rook with checks and it simply rotates; the naive attacker makes forty moves of nothing.
The winning idea is zugzwang, not attack. Centralize the queen where it covers the rook's pivot squares, walk your king up, and pass the move. Out of safe rook squares, the defender must either drop the rook to a fork or let your king in. The classic breakdown position (Philidor's, naturally) is worth knowing by heart: queen and king in opposition-like harmony, defender to move, every reply loses material.
Traps on the way: stalemate after a greedy rook capture, perpetual checks when your king wanders too far, and the fifty-move clock ticking behind everything. The tablebase defender in this drill plays the maximum-resistance rotation: expect to earn every rank.
