In 1895, Edward Freeborough edited an entire 130-page book of analysis of this endgame, titled The Chess Ending, King & Queen against King & Rook. [4]Because it has only four pieces, queen versus rook was one of the first endings to be solved by endgame tablebases. [1]
With a rook pawn, usually in actual play the defending rook or king is able to get in front of the pawn. If the defending king gets in front of the pawn, the game is a draw. If the defending rook gets in front of the pawn, the result depends on which king arrives on the scene first. [61] The attacking king or rook may be in front of the pawn.
A rook versus a minor piece: normally a draw but in some cases the rook wins, see pawnless chess endgame. A rook versus a minor piece and one pawn: usually a draw but the rook may win. A rook versus a minor piece and two pawns: usually a draw but the minor piece may win. A rook versus a minor piece and three pawns: a win for the minor piece.
The chess endgame with a king and a pawn versus a king is one of the most important and fundamental endgames, other than the basic checkmates. [1] It is an important endgame for chess players to master, since most other endgames have the potential of reducing to this type of endgame via exchanges of pieces.
The rook and bishop versus rook endgame is a chess endgame where one player has just a king, a rook, and a bishop, and the other player has just a king and a rook.This combination of material is one of the most common pawnless chess endgames.
Castling is permitted only if neither the king nor the rook has previously moved; the squares between the king and the rook are vacant; and the king does not leave, cross over, or finish on a square attacked by an enemy piece. Castling is the only move in chess in which two pieces are moved at once. [3]
Chess engines usually assign the king an arbitrary large value such as 200 points or more to indicate that the inevitable loss of the king due to checkmate trumps all other considerations. [9] During the endgame , as there is less danger of checkmate , the king will often assume a more active role.
Edward Freeborough wrote a 130-page book of analysis of the queen versus rook endgame, The Chess Ending, King & Queen against King & Rook, which was published in 1895. Henri Rinck (1870-1952) was a specialist in pawnless endgames and A. A. Troitsky (1866-1942) is famous for his analysis of two knights versus a pawn. [26]
