![]() This defense is difficult for a human to defeat. ![]() The third-rank defense is when the rook is on the third rank or file from the edge of the board, his king is closer to the edge and the enemy king is on the other side (see the diagram). With perfect play, in the worst winning position, the queen can win the rook or checkmate within 31 moves. Normally, the winning process involves first winning the rook with the queen via a fork and then checkmating with the king and queen, but forced checkmates with the rook still on the board are possible in some positions or against incorrect defense. In 1895, Edward Freeborough edited an entire 130-page book of analysis of this endgame, titled The Chess Ending, King & Queen against King & Rook. Qf4.Ī queen wins against a lone rook, unless there is an immediate draw by stalemate or due to perpetual check (or if the rook or king can immediately capture the queen). White can win this position in as few as 19 moves with correct play, starting with 1. a book draw).īlack is employing the third rank defense. In some cases, one side of these endgames can force a win in other cases, the game is a draw (i.e. The assessment of endgame positions assumes optimal play by both sides. Grandmaster John Nunn wrote a book ( Secrets of Pawnless Endings) summarizing the research of endgame tablebases for several types of pawnless endings. On the other hand, many of the details and recent results are due to the construction of endgame tablebases. The study of some pawnless endgames goes back centuries by players such as François-André Danican Philidor (1726–1795) and Domenico Lorenzo Ponziani (1719–1796). Other cases that occur occasionally are (1) a rook and minor piece versus a rook and (2) a rook versus a minor piece, especially if the minor piece is a bishop. Endgames without pawns do not occur very often in practice except for the basic checkmates of king and queen versus king, king and rook versus king, and queen versus rook. The basic checkmates are types of pawnless endgames. If you ever get confused during the mating proces, just remember that bishops have to be in synergy.Chess positions with few pieces where none of them are a pawnĪ pawnless chess endgame is a chess endgame in which only a few pieces remain, and no pawns. The example started from the hardest possible starting position, and still the sub-optimal mate was performed in only 24 moves, which is way below the maximum allowed 50 moves which player has according to the rules to perform the mate. ![]() Once you get some experience, you can always consult the N alimov Tablebase tool, a specified computer engine that gives the final evaluation of the endgame position that containes up to 6 pieces on the board.įrom the practical point of view, it is worth remembering the following: Since this example was meant to be educational, it hasn’t followed the fastest way towards the goal. Hopefully, after reading this it will be easier to perform the bishops checkmate once you encounter it over the board. your web browser and/or your host do not support iframes as required to display the chessboard alternatively your wordpress theme might suppress the html iframe tag from articles or excerpts Some of the possible mating pictures are demonstrated on the diagram below (Hint: Note that once again White will be the mating side throughout the whole post) Similarly to the other elementary mates, the mate itself takes place either at the edge, or at the corner of the board. Just in case you were wondering what the hell I was blabbling about above MATING PICTUREįirst of all, we shall follow the familiar track and get acquainted with the mating picture. Therefore, as a next elementary mate we will study the typical mate of the two bishops, a mate that every chess player should be familiar with.Īnd I only wish to add that it is very useful that “double figures” mates start with the bishops, instead of the rooks.īecause it would be much harder for everyone to avoid the rookie mistake and call the rook “ THE TOWER” instead. However, from the bishop onwards, a single piece can’t deliver the elementary checkmate to the bare opponent’s king. If you recall the basic chess rules, the next piece on the relative strength scale is the bishop. After learning elementary queen and rook checkmates it is time to take another “small step” for a chessplayer and learn another elementary mate.
