Home * Evaluation * of Pieces * Bishop Pair

Since in the initial position bishops stand on the squares of different color, throughout the game they control a disjoint sets of squares. This means that their power will never be wasted for carrying out the same tasks. On the other hand, lack of one bishop may introduce a color weakness. Taking all those considerations into account, one might conclude that possessing both bishops is a desirable thing. The question is, however, how much they are worth.

Larry Kaufman proposed the value of half a pawn [1]. It must be stressed, however, that this number is a part of a broader system, in which knights are stronger with many pawns on the board.
