I did not suggest not to give the programs full use of the cpu but only suggested to do something that is leading to the same result as pondering(except the fact that the game is longer. You can do something that is leading to the same outcome by giving more time to the program that expected the move of the opponent. I do not assume as obvious that when you did not expect the right move then those calculations just go out the window because a program can use the information(for example if it found that Bb1 failed high then there is a reason to suspect that Bb1 is going to fail high again for a similiar reason so it can use different order of moves as a result of the previous search). This is the reason that I suggested to give the program time for pondering that is equal to the time that the opponent calculated its move. The only difference between computer-computer games is that pondering of one player and thinking of the second player are not done in the same time. > >I feel that games with weeker programs are more interesting when there is a >noticeable difference in strength. I hate draws, why would you encourage them to >happen? 1)the number of draws between computers is relatively small and if the result is draw then I expect most of the games not to be drawn. 2)If you are working to improve program A and play it against program B then you cannot learn much from the games if program A beats program B. You need to give more time to program B in order to see the problems of program A. Uri
