Two wooden bishops.
The bishop is a piece that looks somewhat like a pawn, but is taller. Bishops are placed on the space between the knight and king or queen. Each player starts out with two, one on the dark squares, and one on the light squares. They move diagonally along their own-colored squares. Bishops are worth 3 points each and are represented by a capital B in algebraic notation.
Strategy
Bishops are extremely useful if played early on in the game. The fact that they move diagonally means that they are often overlooked compared to the more dramatic rook. Since each player's bishops move on separate- colored squares, losing one bishop can leave a player at a disadvantage with squares that cannot be used by the other. Bishops are generally considered to be slightly more useful than knights, particularly during the endgame, despite the fact that both pieces have the same point value.
The most possible moves a bishop can have at once is thirteen.
