There are many different forms of annotation:

 

 

 

  Variations – alternative continuations that can be replayed on the board.

  Text commentary – embedded in the game (e.g. “This is the critical position.”).

  Symbol commentary – in the form of special chess symbols inserted before or after a move.

  Graphic commentary – in the form of coloured arrows and squares on the chessboard.

  Training commentary – with training questions, answers, points, times, help, etc.

  Correspondence chess commentary – to automate the management of correspondence chess games.

  Critical position – critical openings, middlegame and endgame positions.

  Pawn structure and piece path – to highlight the pawn structure or graphically display a piece path.

  Medals – a special award for best game, tournament decider, model game, novelty, repertoire, strategy, tactics, etc.

 

 

The annotation palette is a helpful tool for quick entering of symbol commentary and variations.
