The exchange sacrifice: a rook for a minor piece

Less material, a better position

A rook is usually worth more than a bishop or a knight. The difference is called the exchange, and giving a rook for a minor piece is sacrificing the exchange. You don't do it because it looks nice, but to get something that is worth more right then: an attack on the king, a square where a piece can't be chased away, a broken pawn structure or a blockade.

Exchange sacrifices for an attack

Often the exchange sacrifice tears open the shelter around the king. The rook takes a defending piece, and the other pieces get in. In game six of the 1972 World Championship, Bobby Fischer decided the game that way.

Wilhelm Steinitz did the same against Curt von Bardeleben in 1895, with Black's king still in the middle.

A well-known exchange sacrifice from the openings comes in the Dragon Variation of the Sicilian: Black gives the rook for the knight on c3 and breaks up the pawns in front of White's king. Read about it on the page about opposite-side castling.

Exchange sacrifices for the position

The second kind of exchange sacrifice gives no attack. It gives a better position, and the advantage shows only much later. Tigran Petrosian, World Champion from 1963 to 1969, became known for exactly that. Garry Kasparov has written that Petrosian sacrificed the exchange for the sake of the position, where time hardly plays a part, and that nobody before him had studied it.

A well-known example comes from the 1953 Candidates tournament in Zurich. Samuel Reshevsky had a strong center, and his pawns could get moving. Petrosian's pieces stood passively. He decided to bring his knight to d5, where it would stop White's pawns, and for the knight to get there, the rook on e7 had to move.

Two moves later Reshevsky gave the exchange back with 30.Rxd3, and the game ended in a draw. There is more about Petrosian on his page among the great chess players.

Common mistakes

• Sacrificing without knowing what you get. An exchange sacrifice needs something concrete in return: a square, a weak king, a blockade.
• Counting only material. The side that has won the exchange isn't automatically better. Ask what the opponent's pieces are doing.
• Never giving it back. The side that has won the exchange can often do well to give it back when that removes the opponent's best piece.

Remember

• The exchange is the difference between a rook and a minor piece.
• For an attack: the rook takes the king's defender.
• For the position: a minor piece on a square where nothing can chase it away can be worth a rook.
