The queen versus rook endgame is a chess endgame where one player has just a king and queen, and the other player has just a king and rook. As no pawns are on the board, it is a pawnless chess endgame .
A queen wins against a lone rook, unless there is an immediate draw by stalemate or due to perpetual check [3] (or if the rook or king can immediately capture the queen). In 1895, Edward Freeborough edited an entire 130-page book of analysis of this endgame, titled The Chess Ending, King & Queen against King & Rook.
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.
In a few cases, the superior side gives up their rook in order to promote the pawn, resulting in a winning queen versus rook position (see Pawnless chess endgame § Queen versus rook). A rule of thumb (with exceptions) is: if the king on the side without the pawn can reach the queening square of the pawn, the game is a draw ; otherwise it is a ...
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]
William Steinitz reckoned that often two bishops and two pawns are superior against rook and knight. A rook and bishop usually work better together than a rook and knight in the endgame. [30] [31] José Raúl Capablanca stated that a queen and knight work better together than a queen and bishop in the endgame. [32]
an extra rook is helpful in the "threshold" case, but not otherwise (because two rooks fighting against a queen benefit from the ability to defend each other, but minor pieces against a rook need a rook's help more than the rook needs the help of another rook); a second queen has lower value than normal. In the endgame: [48]
The chess endgame of a queen versus pawn (with both sides having no other pieces except the kings) is usually an easy win for the side with the queen.However, if the pawn has advanced to its seventh rank it has possibilities of reaching a draw, and there are some drawn positions with the pawn on the sixth rank.
