Therefore, a double check forces the king to make a move. In algebraic chess notation, a double check move is sometimes noted with a "++" after the written move in place of the usual "+", although "++" has been used to indicate checkmate (along with "#"). [5] Cross-check.
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 ...
Minimal algebraic notation is similar to short algebraic notation but omits the indicators for capture ("x"), en passant capture ("e.p."), check ("+") and checkmate ("#"). It was used by Chess Informant. [7] Figurine algebraic notation replaces the letter that stands for a piece by its symbol, e.g., ♞c6 instead of Nc6 or ♖xg4 instead of ...
There are other symbols used by various chess engines and publications, such as Chess Informant and Encyclopaedia of Chess Openings, when annotating moves or describing positions. [8] Many of the symbols now have Unicode encodings, but quite a few still require a special chess font with appropriated characters.
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.
In chess and other related games, a double check is a check delivered by two pieces simultaneously. [ 1 ] [ 2 ] In chess notation , it is almost always represented the same way as a single check ("+"), but is sometimes symbolized by "++".
Variants of algebraic notation include long algebraic, in which both the departure and destination square are indicated; abbreviated algebraic, in which capture signs, check signs, and ranks of pawn captures may be omitted; and figurine algebraic notation, used in chess publications for universal readability regardless of language.
A player cannot make any move that places their own king in check. Despite this, the king can become a strong offensive piece in the endgame or, rarely, the middlegame. In algebraic notation, the king is abbreviated by the letter K among English speakers. The white king starts the game on e1; the black king starts on e8.
