BACKWARD PAWN  look up translate image
A Pawn that has trailed behind and is no longer supported by other Pawns. A backward Pawn is consider a fundamental weakness in a Chess position because it can be attacked. Its defense requires pieces that are better employed in other plans. See also isolated Pawn. 1. A pawn at the base of a pawn chain that can't move forward due to one or more enemy pawns on the adjacent files. 2. A pawn which stands on an open file and cannot be protected by any other pawn.
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.

The very last pawn in a diagonal chain. It is the weakest point due to it not being supported by another pawn.
BATTERY  look up translate image

BISHOP PAIR  look up translate image
Two Bishops vs. a Bishop and a Knight or two Knights. If both Bishops on the same side have survived late into a game of Chess, then their value is enhanced for two reasons. Together they can attack a piece on any color square. Their mobility is usually less restricted by Pawns late in the game. Therefore, a Bishop pair is a notable advantage. Two bishops against a bishop and knight or two knights. Two bishops are effective together because they control diagonals of both colours, and work very well in open positions. See "Opposite colour bishops".

BLOCK  look up translate image
A problem in which the key provides no threat, but instead puts black in a position of zugzwang, where every move leads to a mate. In a complete block, all of black's moves have mates provided in the set play and the key is simply a waiting move; in an incomplete block, not all black moves are provided with mates in the set play - the key provides for those that don't; in a mutate some of the mates provided in the set play are changed following the key.
