Learn How to Win a Chess Endgame: Rook Activity
This chess endgame is a classic lesson in rook activity and king coordination. Even with equal material, the more active rook can dominate the board by forcing the enemy king into a passive role, creating tactical threats against loose pawns and weak squares. In classical chess, these positions often turn on tempo: every check, cut-off, and king move matters. The key idea is to use activity to win material or convert a passed pawn, not to chase random checks.
