Portable Game Notation (PGN) is a standard plain text format for recording chess games (both the moves and related data), which can be read by humans and is also supported by most chess software. This article uses algebraic notation to describe chess moves.
2-19: future chess expansion; 20: 10 × 10 draughts (international) 21: English draughts (kings only move 1 step at a time) 22: Italian draughts (as English, Men cannot take kings, must capture max) 23: American pool draughts (as 10 × 10, not obliged to take max) 24: Spanish pool draughts (as 10 × 10 rules, but men cannot capture backwards)
The notation for chess moves evolved slowly, as these examples show. The last is in algebraic chess notation; the others show the evolution of descriptive chess notation and use spelling and notation of the period. 1614: The white king commands his owne knight into the third house before his owne bishop. 1750: K. knight to His Bishop's 3d.
Descriptive notation was usual in the Middle Ages in Europe. A form of algebraic chess notation that seems to have been borrowed from Muslim chess, however, appeared in Europe in a 12th century manuscript referred to as "MS. Paris Fr. 1173 (PP.)". The files run from a to h, just as they do in the current standard algebraic notation. The ranks ...
Time is controlled using a chess clock that has two displays, one for each player's remaining time. Analog chess clocks have been largely replaced by digital clocks, which allow for time controls with increments. Time controls are also enforced in correspondence chess competitions. A typical time control is 50 days for every 10 moves.
Bex notation also adds many extensions for indicating different modes of capture: where a simple c describes replacement capture as in chess, the notations [ca], [cw], [cl] describe capture by approach, withdrawal, leaping over, etc. [crM] describes rifle capture (i.e. annihilating enemy pieces without moving), and specifies with the atom M it ...
X-FEN (formerly FRC-FEN) is an extension of Forsyth–Edwards Notation (FEN) introduced by Reinhard Scharnagl in 2003. [1] It was designed to be able to represent all possible positions in Fischer random chess (FRC) and Capablanca random chess (CRC). It is fully backward compatible with FEN.
The only possible reply to a double check is a king move, as it is impossible to block or capture both checking pieces at once. In exceptional circumstances, it is possible for the moved piece in a double check to not give check. The only way for this to happen in orthodox chess is by way of an en passant capture. In the position shown from ...
