Definition: An annotation is a collection of written comments about a game, a position, or a move, including variations, explanatory text, or both. In annotating, an annotator attempts to explain why a game was won or lost.
Symbols may be used after noteworthy moves. The following table shows the most common symbols.
- !! : a brilliant move
- ! : an excellent love
- !? : a move deserving attention
- ?! : a dubious move
- ? : a weak move
- ?? : a blunder
Annotation should not be confused with notation, which is a method for recording moves. An annotation can be done using any notation.
