The Power Of The Exchange Sacrifice In Chess

Exchange Sacrifice

In simple terms, an exchange sacrifice is said to occur on the chess board when a rook is exchanged for the opponent’s bishop or knight for positional or tactical merits or even as a means of stopping the other side counterplay. The exchange sacrifice usually brings about an imbalance in the position where material advantages may be irrelevant as certain positional and tactical concepts such as the control of open files, lead in development, domination of weak squares in the opponent’s camp, coordination of pieces e.t.c. will turn out to be the deciding factors in the game. The exchange sacrifice can be very useful in the following ways:

  1. To destroy your opponent pawn structure: There are tactical ideas usually attached to this factor. For example, If white has a rook on an open f-file and black king has castled and black has a knight on the f6 square with no piece supporting this knight; most players would not hesitate to play Rxf6 destroying the pawn structure as black would have to recapture with gxf6 exposing the king to further danger. This kind of idea is also common in the Sicilian defense where black plays Rc8xNc3.
  2. To establish a minor piece on a strong square: In the same way, white can sacrifice his rook to gain total control over an important square in the opponent’s territory.
  3. To dominate weak squares in the opponents camp
  4. Lead in development
  5. To achieve connected passed pawns

The exchange sacrifice is commonly played by experts and masters as most beginners and intermediate players have difficulties parting with material plus the fact that it would be difficult for them to exploit the positional advantages brought about by the exchange sacrifice. The exchange sacrifice was one of the trademark resource of Tigran Petrosian.

Tigran Petrosian was the ninth world chess champion. He was known for his ultra-solid and defensive style of playing which earned him the nickname “Iron Tigran”. He brought about a new look to exchange sacrifices, He knew how to steer the position in a way that would favor him by making use of the accumulated positional or tactical advantages. Below is one of his games against Samuel Reshevsky in the 1953 candidates tournament.

Petrosian was playing with the black pieces in this game. In the position shown above, black appears cramped while white pieces are poised for action except the b2-bishop which looks more like a tall pawn. If white is allowed to play Bf3 and d5 then black would be doomed. Petrosian saw these possibilities and deduced that the black knight would be better placed on the d5 square blockading the white pawns, attacking the c3 pawn and supporting a potential b5-b4 pawn break creating a passed pawn in the process. The knight can easily be transferred to the d5 square through the e7 square however any move such as Ra7 or Rc7 making way for the knight would punished by e6!. Petrosian however finds a subtle way of achieving this maneuver.

[ Black willingly offers an exchange sacrifice. After 26. Bxe6 fxe6, Black would have adequate compensation as the knight would sit comfortably on the d5 square and black would achieve a light square blockade using the light squared bishop. The position would result in a draw with accurate moves from both sides.]

26. a4?! [ White sets up a little trap ]

26… Ne7! [ 26… b4?! is inaccurate as white would go 27. d5! Rxd5 28. Bxe6 fxe6 29. Qxc4 and the position is more open and in white’s favor]

27. Bxe6 fxe6

28. Qf1 Nd5 29. Rf3 Bd3 30. Rxd3 [White returns the exchange as 30… b4 was imminent, The position is now drawish and the game ended in a draw. ] 31. Qxd3

This is another great example shown below. Tigran petrosian was black playing against Lev Polugaevsky in Moscow, 1983.

In the position above, it is clear that white has some pressure on the queenside i.e on the b6 square and the b7 pawn while black has eyes on the weak c4 pawn and seeks to exploit the weak c5 square. White dark squared bishop displays radiance holding white position a lot and pressuring the weak dark squares in black position. Petrosian decides to take this valuable bishop after concluding that the bishop was better than his rook at e8

19… Rxe3! 20. fxe3 Nc5! [Black now establishes his knight on the c5 square protecting the b7 pawn and clamping down on the e4 pawn]

21. Qc2 Re8

image 15

[Black now directs his pieces on black’s weak pawn on e3 ]

22. Rf3 Bh6 23. Qc3 Qe7

image 17

24. Rb6 [A terrible blunder, Black position is practically more favorable than that of white, The rook sac probably had a psychological effect on Polugaevsky ]

24… Na4 [Black wisely resigned, the game may have continued 25. Qd4 Nxb6 26. Qxb6 Bxe3+ 27. Rxe3 Qxe3+ 28. Qxe3 Rxe3 and it is now black who is “up the exchange”
