Rook endgames: an active rook beats an extra pawn

More games are decided in a rook endgame than any other kind — rooks are the last pieces traded, so a huge share of games that reach an endgame reach this one. The good news is that rook endgames run on a small number of rules that do most of the work, and the biggest one is this: an active rook is worth more than a pawn.

Get behind the passed pawn

Whether you're pushing a passed pawn or stopping one, the rook belongs behind it, not beside or in front of it (the Tarrasch rule). A rook behind its own passed pawn supports its advance every step of the way; a rook behind the enemy's passed pawn keeps hitting it however far it runs. A rook stuck in front of its own pawn, by contrast, actually gets in the pawn's way.

Cut the enemy king off

A rook on an open file or rank can wall the enemy king away from the action entirely — if the defending king can't reach the pawn, the pawn queens. Cutting the king off by even one file is often worth more than winning a pawn, because a rook-and-pawn endgame is frequently a race between the two kings, and you've just disqualified one of them.

Don't trade an active rook for a passive one

It sounds obvious until you're in the position: a passive rook offers a trade, and taking it feels like simplifying toward a win. Often it throws the win away. If your rook is doing real work — cutting the king off, harassing pawns, ready to check — keep it on the board even at the cost of a pawn. A pawn down with the only active rook is very often better than level material with two inert rooks.

Rook endgames reward patience and technique over calculation fireworks. Learn these three ideas and you'll hold draws you used to lose, and convert wins you used to let slip.
