Opposite-colored Bishops Endgame
The opposite-colored bishops endgame is a chess endgame in which each side has a single bishop and the bishops reside on opposite-colored squares. Without other besides pawns, these endings are widely known for their tendency to result in a draw. These are the most difficult endings in which to convert a small advantage to a win. With additional pieces, the stronger side has more chances to win, but not as many as when bishops are on the same color. Many players in a poor position have escaped a loss by trading down to such an endgame. These endgames are sometimes drawn when one side has an advantage of two or even three pawns, since the weaker side can create a blockade on the squares on which their bishop operates. General principles Edmar Mednis gives two principles for endgames with bishops on opposite colors: # If a player is down he should look for drawing chances in an endgame with only the bishops and pawns. # With (queen or rook) on the board, having bishops on ...

Chess Kll45
Chess is a board game for two players, called White and Black, each controlling an army of chess pieces in their color, with the objective to checkmate the opponent's king. It is sometimes called international chess or Western chess to distinguish it from related games, such as xiangqi (Chinese chess) and shogi (Japanese chess). The recorded history of chess goes back at least to the emergence of a similar game, chaturanga, in seventh-century India. The rules of chess as we know them today emerged in Europe at the end of the 15th century, with standardization and universal acceptance by the end of the 19th century. Today, chess is one of the world's most popular games, played by millions of people worldwide. Chess is an abstract strategy game that involves no hidden information and no use of dice or cards. It is played on a chessboard with 64 squares arranged in an eight-by-eight grid. At the start, each player controls sixteen pieces: one king, one queen, two rooks, two bi ...

Wrong Rook Pawn
In chess chess endgame, endgames with a bishop (chess), bishop, a pawn (chess), pawn that is a may be the wrong rook pawn. With a single bishop, the result of a position may depend on whether or not the bishop controls the square on the chessboard on which the pawn would promotion (chess), promote. Since a side's rook pawns promote on opposite-colored squares, one of them may be the "wrong rook pawn". This situation is also known as having the ''wrong-colored bishop'' or ''wrong bishop'', i.e. the bishop is on the wrong colored squares in relation to the rook pawn. In many cases, the wrong rook pawn will only draw (chess), draw, when any other pawn would win. A fairly common defensive tactic is to get into one of these drawn endgames, often through a sacrifice (chess), sacrifice. In some endgames such as having a bishop and pawn versus a lone king (chess), king (perhaps with pawns), the wrong rook pawn is the one whose promotion square is the opposite color as that on which the bi ...

Fortress (chess)
In chess, a fortress is an endgame drawing technique in which the side behind in sets up a zone of protection that the opponent cannot penetrate. This might involve keeping the enemy king out of one's position, or a zone the enemy cannot force one out of (e.g. see the opposite-colored bishops example). An elementary fortress is a theoretically drawn (i.e. a ) position with reduced material in which a passive defense will maintain the draw. Fortresses commonly have the following characteristics: # Useful pawn are not possible. # If the stronger side has pawns, they are firmly blocked. # The stronger side's king cannot penetrate because it is either cut off or near the edge of the board. #Zugzwang positions cannot be forced because the defender has available. Fortresses pose a problem for computer chess: computers fail to recognize fortress-type positions and are unable to achieve the win against them despite claiming a winning advantage.

Promotion (chess)
In chess, promotion is the replacement of a pawn with a new piece when the pawn is moved to its last . The player replaces the pawn immediately with a queen, rook, bishop, or knight of the same . The new piece does not have to be a previously captured piece. Promotion is mandatory; the pawn cannot remain as a pawn. Promotion to a queen is known as queening; promotion to any other piece is known as underpromotion. Promotion is almost always to a queen, as it is the most powerful piece. Underpromotion might be done for various reasons, such as to avoid stalemate or for tactical reasons related to the knight's unique movement pattern. Promotion or the threat of it often decides the result in an endgame. Rules When a pawn is promoted, it is removed from the board, and the new piece is placed on the square of promotion. A piece may be promoted to regardless of whether it has been captured. Consequently, a player might have two or more queens, or three or more rooks, bishops, or kni ...
