You must change the contempt value through the engine parameter dialogue box. Right click on the engine name at the top of the engine window and click on engine parameters. Now adjust the contempt value in pawn value (1 pawn = 100) From the help file <quote> Contempt value: A very strong program can sometimes trick itself into a draw by showing too much respect for the opponent. On a fast machine, the program may suddenly start to repeat moves, because it has seen some very deep lines which is slightly better for the opponent (even though the opponent has no chance of actually finding the line). To counteract this tendency, we have introduced a "contempt factor", which essentially tells the program to play on against weak opponents. Setting a positive contempt value will cause the program to avoid draws, while a positive value will make it go for a draw even if it thinks it is better. This essentially shows respect for the opponent. The value is in hundredths of a pawn, so setting 50 means that the program will play for a win, even if it thinks its half a pawn down (which can easily be the case in certain openings). If the program is playing against a top grandmaster it is usually better to set minus 50, so it will play overconfidently and take a draw if the opportunity arises. </quote> J.
