{{Short description|Graphic depiction of a given position in a game of chess}}

A '''chess diagram''' is graphic representation and stylized of a specific moment in a [[chess]] game, showing the different positions occupied by chess pieces in given time during game development.

A '''chess diagram''' is graphic representation of a position in a [[chess]] game, using standardised symbols. Chess diagrams are widely used in chess publications as an aid to visualisation, or to aid the readers to verify that they are looking at the correct position on their [[chessboard]] or computer. The symbols used generally resemble the pieces of the standard [[Staunton chess set]], although a number of different fonts have been used over the centuries.
