SAN kingside castling is indicated by the sequence O-O; queenside castling is indicated by the sequence O-O-O (note that these are capital Os, not zeroes, contrary to the FIDE standard for notation). [4] Pawn promotions are notated by appending = to the destination square, followed by the piece the pawn is promoted to. For example: e8=Q.
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.
Some chess variants do not feature castling, such as losing chess, where the king is not royal, and Grand Chess, where the rooks have significantly more opening mobility. In a handicap game with rook odds, the player giving odds may castle with the absent rook, moving only the king.
Portable Game Notation (PGN) is a text-based file format for storing chess games, which uses standard English algebraic notation and a small amount of markup. [11] PGN can be processed by almost all chess software, as well as being easily readable by humans.
However, the FEN castling availability encoding (KQkq) is inadequate when both rooks are on the same side of the king on the back rank (as a result of one rook having moved, or in a form of randomised chess that allows it in a starting position): if either rook is still available for castling, it would be ambiguous which rook this is without ...
The example below is for the opening position, so no moves are shown in the heading. The first row provides the move numbers with subsequent rows representing different variations. Since the initial position is not always the opening position, these numbers will not always start at "1." White half-moves are shown above black half-moves.
This example uses algebraic notation. In chess , a king walk , also known as a king march , steel king , or wandering king ( Dutch : wandelkoning , literally "wanderking"), is a maneuver where the king travels a large distance to a different part of the board in the middlegame or opening .
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.
