Plaskett's Puzzle is a chess endgame study created by the Dutch endgame composer Gijs van Breukelen (February 27, 1946 – December 21, 2022) around 1970, although not published at the time. Van Breukelen published the puzzle in 1990 in the Netherlands chess magazine Schakend Nederland .
Not all chess games reach an endgame; some of them end earlier. All chess positions with up to seven pieces on the board have been solved by endgame tablebases , [ 2 ] so the outcome (win, loss, or draw) of best play by both sides in such positions is known, and endgame textbooks teach this best play.
In the game of chess, an endgame study, or just study, is a composed position—that is, one that has been made up rather than played in an actual game—presented as a sort of puzzle, in which the aim of the solver is to find the essentially unique way for one side (usually White) to win or draw, as stipulated, against any moves the other side plays.
Endgame chess (or the Pawns Game, with unknown origins): Players start the game with only pawns and a king. Normal check, checkmate, en passant, and pawn promotion rules apply. [6] Los Alamos chess (or anti-clerical chess): Played on a 6×6 board without bishops. This was the first chess-like game played by a computer program.
The Saavedra position is one of the best-known chess endgame studies. It is named after the Spanish priest Fernando Saavedra (1849–1922), who lived in Glasgow during the late 19th century. Though not a strong player, he spotted a win involving a dramatic underpromotion in a position previously thought to have been a draw .
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 joke chess problem is a puzzle in chess that uses humor as an element. Although most chess problems, like other creative forms, are appreciated for serious artistic themes (such as Grimshaw, Novotny, and Lacny), joke chess problems are enjoyed for some twist. In some cases the composer plays a trick to prevent a solver from succeeding with ...
The Lucena position is a position in chess endgame theory where one side has a rook and a pawn and the defender has a rook. Karsten Müller said that it may be the most important position in endgame theory. [1] It is fundamental in the rook and pawn versus rook endgame. If the side with the pawn can reach this type of position, they can ...
