Some comments (scores, depth, variations) will be written in annotated.pgn. If annotated.pgn already exists, the PGN will be appended. gameno is the number of the game in games.pgn (if there is only one game, use 1). Seconds is the time to analyze each move. fhmn and lhmn are the first/last *half* move numbers to analyze. if smaller 0, the start/end of the game will be meant. side is either w, b or a (for white, black, all). Margin is a score margin. When the score of the Yace suggested move is better than this margin, a variation will be written in the game. It can be set to 0 or < 0, which means any alternative will be shown. example: annotate match.pgn matchann.pgn 1 10 a -1 -1 0 In this example, the last four parameters would actually not be needed, because they are the defaults. If you want to annotate more than one game (say over night), you could write an input file, ann.inp like: annotate games.pgn gamesa.pgn 2 100 w 20 80 5 annotate games.pgn gamesa.pgn 5 100 w 20 80 5 annotate games.pgn gamesa.pgn 7 100 w 20 80 5 to annotate games 2 5 and 7. At the Yace prompt, you would type inp ann.inp At the moment all scores shown in the annotated pgns will be from the view of the moving side. In later versions, this can be changed.
