A '''chess diagram''' is graphic representation of a specific momentposition in a [[chess]] game, showing the different positions occupied by the pieces. This is done by the use ofusing standardised symbols. Chess diagrams are widely used in chess publications as an aid to visualisation, or to aid the reader to verify that they are looking at the same position on their [[chessboard]] or computer. The symbols used generally resemble the pieces of the standard [[Staunton chess set]], but a number of different fonts have been used over the centuries.
