BAD BISHOP look up translate image
Any ineffective Bishop. When a Bishop has little or no mobility because of being hemmed by Pawns positioned on squares of the same color as the Bishop's square, it is said to be a "bad Bishop".

A bishop whose movement is restricted by friendly pawns on its colour squares. These friendly pawns are in turn restricted by enemy pawns or pieces, thereby being unable to vacate squares for the bishop.
