Here is a few his rules I learnt: try different >programs; try different methods of analysis; don't use long analysis time - I disagree with the rule not to use long analysis. Using long analysis time can be productive for finding good moves that you cannot find without it. >mostly it is waste of time; always continue the variations supposed by programs >(even if analysis time was long) I believe that it is a good rule to try in many cases only in corresponence games. - programs can easily change it's evaluation >from plus to minus after a few moves; learn the program - try different >variations and return back; learn yourself with the results and try your own >moves - nothing bad if program rejects them quickly - once you will offer a good >move that no one program can find. > >Victor what is the time control that your friend is playing? If you talk about correspondence games so I suspect that the main reason that he is winning is using more computer time than the opponents. Uri
