Since in the [[Initial Position|initial position]] [[Bishop|bishops]] stand on the [[Squares|squares]] of different [[Color|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.

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.
