Regular time/move is just _one_ thing we look >for. There are many other 'signatures' on a computer-user... James suggested also occasionally to make tactical mistakes. Of course it is not going to be the best program but it can help the cheater to get better rating. I also think it is dengerous to say that someone is a computer only based on the fact that there were no tactical mistakes. There are many draws between humans with no tactical mistakes. I have some draws from my tournament games when I did not do a tactical mistake and my opponent also did not do a tactical mistake. I cannot say that somebody is a cheater in standard time control only because (s)he knows to play with no tactical mistakes in most of the games. Uri
