Rook Endgames: Piece Activity

The Rook Endgames: Piece Activity is a rook endgame involving R+PP vs R+PP. In rook endgames with equal material, the activity of the rook is often more important than the pawn structure. Tarrasch's rule says rooks belong behind passed pawns — whether your own or your opponent's. An active rook (cutting off the enemy king, attacking pawns from behind) can compensate for a pawn deficit. A passive rook defending a pawn often leads to a slow loss.

The key concept in the Rook Endgames: Piece Activity is: Active rook beats passive rook. Understanding this principle is more important than memorizing exact move sequences — once you grasp the underlying idea, you can navigate the position even when the move order varies slightly from the textbook line.
