5.7 Scoring the game

GNU Go can score the game. If done at the last move, this is usually accurate unless there is a seki. Normally GNU Go will report its opinion about the score at the end of the game, but if you want this information about a game stored in a file, use the `--score' option.

gnugo --score last -l filename

loads the sgf file to the end of the file and estimates the winner after the last stored move by estimating the territory.

gnugo --score end -l filename

loads the sgf file and GNU Go continues to play after the last stored move by itself up to the very end. Then the winner is determined by estimating the territory.

gnugo --score aftermath -l filename

loads the sgf file and GNU Go continues to play after the last stored move by itself up to the very end. Then the winner is determined by the most accurate algorithm available. Slower but more accurate than `--score end'.

gnugo --score L10 -l filename

loads the sgf file until a stone is placed on L10. Now the winner will be estimated as with gnugo --score last.

Any of these commands may be combined with `--chinese-rules' if you want to use Chinese (area) counting.

gnugo --score 100 -l filename

loads the sgf file until move number 100. Now the winner will be estimated as with gnugo --score last.

If the option `-o outputfilename' is provided, the results will also be written as comment at the end of the output file.
