I am surprised that people think that it is done to win(it is done to win only if it is done only when the opponent is in big time trouble). I also have a parameter that tells the public movei to play faster so if opponents think that it is too strong for them they can change the parameter from 1 to 60 and movei is going to play 60 times faster. I never thought that it is going to give movei better rating but I also thought about comp-comp and not about comp-human. The main reason for this function is the fact that winboard does not support unequal time control and if I want to test if my program is 5 times better or 10 times better than another program I have no way to do it without a special function. I found that public movei is more than 5 times better than tscp only when the time control is slow enough. Unfortunately other engines do not support this function so I cannot find how much speed movei need to be better than Ruffian but people can get an estimate if they play games of x minutes/y moves when y is a big number of some thousands thanks to the bad time management of ruffian. Again I suspect that the difference between the public movei and Ruffian becomes bigger when the time control is slower but today I do not care about the public movei. Uri
