Chess piece relative value of bishops is stronger than two rooks plus a knight . This situation is very rare. Black is ahead by counting material but in reality white is much better. White's queenside is perfectly defended. White can slowly build up pressure on black's weakened kingside. Black's extra queen has no target. White's dark-squared bishop is stronger than black's passive rook on f8. Principle of the redundancy of major pieces. Neither queen does anything that the other one cannot do. Chess piece relative value In chess, the chess piece relative value system conventionally assigns a point value to each piece when assessing
Algebraic notation (chess) Philipp Stamma. Stamma used the modern names of the squares, but he used "p" for pawn moves and the original of a piece ("a" through "h") instead of the initial letter of the piece name. This article describes standard algebraic notation (SAN) required by FIDE. Each square of the chessboard is identified by a unique coordinate pair—a letter and a number. The vertical columns of squares, called ', are labeled "a" through "h" from White's left (the ) to right (the ). The horizontal rows of squares, called ', are numbered "1" to "8" starting from White's side of the
