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]
[1] [2] Although it is classified as one of the four basic checkmates, [3] [a] the bishop and knight checkmate occurs in practice only approximately once in every 6,000 games. [ 4 ] This article uses algebraic notation to describe chess moves.
The bishop and knight mate is one of the four basic checkmates and occurs when the king works together with a bishop and knight to force the opponent king to the corner of the board. The bishop and knight endgame can be difficult to master: some positions may require up to 34 moves of perfect play before checkmate can be delivered.
The chess machine is an ideal one to start with, since: (1) the problem is sharply defined both in allowed operations (the moves) and in the ultimate goal (checkmate); (2) it is neither so simple as to be trivial nor too difficult for satisfactory solution; (3) chess is generally considered to require "thinking" for skillful play; a solution of ...

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.
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 ...
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 ...
