Sorry, but those two statements are the _same_ thing: 1. GT needs a faster processor to do ok; 2. GT needs more time to do ok; Interesting that I have said this many times about my program (ponder=off hurts it, etc) and continually get pooh-pooh'ed about the idea. :) Of course, I don't "believe" that is true. I _know_ it is true for my program. > >It needs some depth to reach realistic plans. I cannot say in absolute how much >depth is necessary, because it depends on the position.

Which I can neither confirm nor deny for your program of course. But it has _always_ been true for mine. I have given lots of reasons why, from aggressive null-move, to code that is not terrifically fast due to trying to keep things understandable. > > >>if so, then claims by other chess programs that they play better at longer time >>controls may be accurate also... > > >I know where you are trying to pull me, but it does not work this time. ;) > > > > Christophe It did whether you wanted it to or not. :)
