A method for checkmate applicable when the lone king is in the corner of the opposite color from the bishop (the "wrong" corner, where checkmate cannot be forced), was given by François-André Danican Philidor in the 1777 update [5] to his famous 1749 treatise, L'Analyse des Échecs. [6]
In contrast to a king and two bishops (on opposite-colored squares), or a bishop and a knight, a king and two knights cannot force checkmate against a lone king (however, the superior side can force stalemate [1] [2]). Although there are checkmate positions, a king and two knights cannot force them against proper, relatively easy defense. [3]
The Traxler Counterattack, also known as the Wilkes-Barre Variation, is a chess opening that begins with the moves: . 1. e4 e5 2. Nf3 Nc6 3. Bc4 Nf6 4. Ng5 Bc5!?. The opening is a variation of the Two Knights Defense [1] [2] where White has chosen the offensive line 4.Ng5, immediately attacking the f7-square with the knight and bishop, and Black has replied 4...Bc5, counterattacking the f2-square.
The knight (♘, ♞) is a piece in the game of chess, represented by a horse's head and neck. It moves two squares vertically and one square horizontally, or two squares horizontally and one square vertically, jumping over other pieces. Each player starts the game with two knights on the b- and g-files, each located between a rook and a bishop ...
The end result of Philidor's mate: 1.Qg8+ Rxg8 2.Nf7# In chess, a smothered mate is a checkmate delivered by a knight in which the mated king is unable to move because it is completely surrounded (or smothered) by its own pieces, which a knight can jump over. The mate is usually seen in a corner of the board, since only three pieces are needed ...
Samuel Boden. Boden's Mate is a checkmating pattern in chess characterized by bishops on two criss-crossing diagonals (for example, bishops on a6 and f4 delivering mate to a king on c8), with possible flight squares for the king being occupied by friendly pieces or under attack by enemy pieces.
An unexpected result from empirical computer studies is that the princess (a bishop-knight compound) and empress (a rook-knight compound) have almost exactly the same value, even though the lone rook is two pawns stronger than the lone bishop. The empress is about 50 centipawns weaker than the queen, and the princess 75 centipawns weaker than ...
In chess, a back-rank checkmate (also known as a corridor mate) is a checkmate delivered by a rook or queen along the opponent's back rank (that is, the row closest to them) in which the mated king is unable to move up the board because the king is blocked by friendly pieces (usually pawns) on the second rank.
