What is a bishop in chess?

In chess, a bishop is one of the six different types of pieces and is represented by a symbol of a bishop's mitre. Each player starts with two bishops – the white bishop on a white square and the black bishop on a black square. Bishops can move diagonally across the board, and they can only move along their colored squares. This means that there are light-square bishops and dark-square bishops. Bishops are considered minor pieces, along with knights, while the queen and rooks are major pieces. Bishops can be quite powerful in the end game, especially when they are positioned close to the opponent's king.
