I remember that my shredder5.32 needed more time Your hardware is better than my PIII850 but it cannot be the only reason because I remember that it was not something like 5 minutes but more than it. I still remember that programs like Deep Fritz were even faster than 2:59. The interesting next test is how much time does shredder5 need to play Rb5 and not Rc2 after 3.Kd4 in your main line. Uri
