In a two knights endgame, the side with the king and two knights cannot checkmate a bare king by force. This endgame should be a draw if the bare king plays correctly. A mate only occurs if the player with the bare king blunders. In some circumstances, if the side with the bare king instead has a pawn, it is possible to set up this type of ...
The two bishops checkmate is the checkmate of a lone king by the opponent's two bishops and king. [b] The superior side is able to drive the lone king into a corner and force mate using the two bishops and king collaboratively. The only stipulation is that the two bishops must move on opposite-colored squares.
They can range from a simple "Mate in one" combination to a complex attack on the opponent's king. Solving tactical chess puzzles is a very common chess teaching technique. Although it is unlikely that the same position will occur in a game the student plays, the recognition of certain patterns can help to find a good move or plan in another ...
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]
The two knights endgame is a chess endgame with a king and two knights versus a king. 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]).
A double check is a check from two pieces to the opponent's king in a single move. This happens when a moved piece attacks the king, resulting in a second piece giving check by discovered check. It can also happen, though very rarely, when an en passant capture opens two lines of attack simultaneously. A double check cannot be blocked, nor can ...
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. [1]
Sacrifices leading to checkmate are typically forcing, and often checks, leaving the opponent with only one or a few options. Avoiding loss The counterpart to the above is saving a lost game. A sacrifice could be made to force stalemate or perpetual check, to create a fortress, or otherwise force a draw, or to avoid even greater loss of material.
