When annotating chess games, commentators frequently use question marks an exclamation points to denote a move as bad or good. The symbols normally used are "??", "?", "?!", "!?", "!", and "!!". The corresponding symbol is juxtaposed in the text immediately after the move (e.g. Re7? or Kh1!?, see algebraic chess notation). Use of these annotation symbols is always somewhat subjective, as different annotators use the same symbols differently.
