It has been said that in a game of human chess, the players posing as the bishop and the knight would be in for an energetic game. On the chess board, the bishop is a strategically effective piece, especially when it gets out to the central squares. With two bishops of a color side by side on two of the four most central squares, they will dominate the four squares directly in front of them, as well as the four behind them. If your winning strategy is to effectively use your bishops, remember to keep them unblocked. Blocked bishops have very little power.
Rooks are considered a more effective piece than a bishop; rooks can travel the board on all squares of both colors, albeit only in straight lines at a time. Bishops are limited to staying only on one color, making the rook more powerful. However, there are ways to use your bishop more effectively than the opposing color’s rook. A bishop on the seven-rank can prevent capture of a promotion bound pawn on the g-file. By being ready to sacrifice itself, the bishop can prevent the capture of a newly-queened pawn. This was a strategy used against World Champion Bobby Fischer, in a match against Russian Grand Master, Boris Spaasky.
In the three parts of a chess match, opening, middle and endgame, the real drama of the game begins with endgame strategies. In the opening game, use your pawns to free the way for the bishops to move into the open. The middle game is mostly defensive, with players trying to keep their most effective pieces from capture. In the endgame, the bishop becomes more powerful as other pieces leave the board. The bishop pair, on both colors of open diagonals, can be more powerful in creating an instant checkmate situation than two knights together. With two attacking knights, two bishops can force a king to the edge of the board, and into a corner, where the king cannot avoid checkmate.
