Perpetual chess

from Wikipedia, the free encyclopedia

Perpetual check or eternal chess means a situation in chess in which a king successive opposing chess commandments neither escape nor can reverse that by interposing dragging stones. This ends the game in a draw , either by repeating the position or - in rare cases - by the 50-move rule . According to the rules of the World Chess Federation FIDE , either player can request a draw as soon as the requirements according to one of these rules are met.

Perpetual chess is usually forced by a player who assesses his position as worse and wants to take the opportunity to end the game with at least a draw. This can be the case, for example, if an attack in the middlegame, for which material was sacrificed , does not lead to mate , but the opposing king cannot escape checks. A typical example is the so-called immortal draw game . Perpetual chess is also a frequently encountered motif in women's finals .

The example diagram shows a typical permanent chess constellation from a game between Bobby Fischer and the then world champion Michail Tal during the Chess Olympiad in Leipzig . Black is in material residue and now gives check with the queen on the squares g4 and f3 , whereupon the white king oscillates between h1 and g1 .

Another example can be found in the advisory game readers from Pionerskaya Pravda - Mikhail Tal , which also ended with a perpetual check.

The studies of Filip Semjonowitsch Bondarenko and Hermann Rübesamen also end with perpetual chess.
