Menu File – Options – Version

This tab groups the settings used when running the program in tournament conditions. The group is labelled "Tournament settings" and contains the following controls:
Tournament version
This switches to a special mode in which the area surrounding the board turns red when the program has made a move. This is useful as a signal for a human operator, especially when the program is playing against a human opponent and it is not acceptable to have a sound signal switched on. The option is only meaningful for such encounters, and not of relevance to normal users.
Log file: this causes the program to keep a log file of the game, so that everything can be checked meticulously after an important tournament game. The file can be printed out and given to the arbiter.
PGN: here you can specify a file for a PGN record of the game. It is updated every time a move is made, and contains the moves and the evaluation of the program. This function is useful for publishing games on the internet.
Opponent: a free-text field (up to 30 characters) for the name of the human opponent. The name is used in the PGN header and in the log file.
Operating time: you can specify how much time the program should deduct from its own thinking time in order to compensate for the lag of a human operator, who needs some time to register and enter the move of the opponent (and execute the computer moves on the official chessboard).
