Rook Endgames

Rook Endgame Fundamentals

Depends on setup
Position Setup

Various common rook endgame positions: King plus Rook plus Pawn vs King plus Rook, with pawn on various files and ranks. Rook endgames are the phase that shows up most often in tournament practice.

Definition

Rook endgame fundamentals cover broader principles than specific Lucena or Philidor: (1) active rook worth 1.5-2 pawns, (2) active king in endgame worth 1 pawn plus, (3) rook behind passed pawn (Tarrasch rule), (4) rook on 7th rank forces opponent king back. These are general principles for all rook endgames.

Core Ideas and Principles

Tarrasch Rule: rook should be behind passed pawn (either own pawn or opponent's pawn). If in front, rook blocks own pawn's path; if approaching opponent's pawn, rook attacks. Tarrasch rule is the most important rook endgame principle frequently violated by amateur players.

Key Move Sequence

Tarrasch example: White pawn on a5 (passed), rook should be on a1 (behind). If on a1, rook supports pawn advance to a8; if on a8 (in front of pawn), rook must retreat every pawn push, losing tempo.

Common Mistakes

  1. 01
    Mistake

    Passive rook on rank 1 defending pawn, but not actively attacking opponent.

    Correction

    Active rook beats passive rook. Better to trade pawn for activity than hold pawn with passive rook.

  2. 02
    Mistake

    Passive king at board edge in endgame. This loses 1 pawn worth of activity.

    Correction

    Active king to center or toward own passed pawn before pawn advance. King activity is proven to be worth 1 pawn in endgame technique.
