Double Exchange Sacrifice
While exchange sacrifice is a very common strategical tool for achieving positional transformation, a double exchange sacrifice is rare guest in the tournament practice. The material deficit is bigger and it is harder to obtain positional compensation. In addition, the opponent can always be alert to give one exchange back and kill the counterplay, while still keeping some extra material at hand.
In our example we have a setup that resembles pawn structure resulting from Nimzo-Indian or Ragozin defence. White’s position looks very appealing at the first glance. He has pair of Bishops and prepares to roll the central pawns with e3-e4. Black h5-pawn also seems to be running ahead of the time and can become target for White pieces.
White’s next move looks natural, the Knight presses h5 and supports the advance e3-e4.
