Rook endgames: the active rook and the rook behind the pawn

The most common endgames

The rooks often come into play last, and they are often traded last. That's why they are still there when the queens and the minor pieces are already gone, and why so many games end up in rook endgames. They are hard, too: a rook that is a little more or a little less active can make the difference between a win and a draw.

Principle 1: an active rook

A rook wants to move. A rook that only stands guarding a pawn, or is stuck in front of a passed pawn, is passive, and then your opponent is in effect playing with an extra piece. An active rook attacks pawns, cuts off the king or gives checks. Getting the rook active is often worth a pawn.

Principle 2: the rook behind the passed pawn

Siegbert Tarrasch put the rule into words: rooks belong behind passed pawns. That goes for both your own and your opponent's. Behind your own passed pawn, the rook gets more room with every step the pawn takes. In front of it, the rook is in the way, and the further the pawn goes, the less room the rook has.

Look at these two positions. The pawns and the kings stand the same; the only difference is where the rooks stand.

In the first position White's rook is stuck in front of the pawn, while Black's rook is active behind it. A draw. In the second it is the other way around, and then White wins.

The rook in front of the pawn: watch out for the skewer

If the rook does end up in front of the pawn, for example with the pawn on the seventh rank, it has one last trick. The rook leaves the a-file, and if the defender takes the pawn, a check along the seventh rank skewers the king and the rook.

That's why Black defends with the king on g7 or h7, where there is no check. Read more about the trick on the page about the skewer.

Principle 3: cut off the king

With rook and pawn against rook, most of it is about the kings. If your rook can cut the defender's king off from the pawn along a file, it becomes much easier to win. The further away the king is cut off, the better.

One file makes a difference. With the king two files away White wins, but only with exact play. With the king one file closer, Black holds the draw. Winning these endgames is often about reaching a Lucena position, and defending them about reaching a Philidor position.

Practice against the computer

Try Tarrasch's rule yourself. You have White, with the rook behind the passed pawn. Take the pawn to the last rank, or force Black to give up the rook for it. The computer defends Black.

Remember

• An active rook before material. A passive rook is almost a rook down.
• The rook behind the passed pawn, both your own and your opponent's.
• Cut off the king from the pawn, preferably several files away.
• Know two positions: Lucena to win and Philidor to hold the draw.
