As for longer T/Cs I really don't know....it would have to have at least 100 games to begin to mean anything and I only have this computer to work from, for the time being. Certainly I'm not going to run a 100 game match from _one_ machine at 40 in 2! IMO Fritz Shredder and Tiger are all very powerful engines, even on a slow PIII 500:o) I'd guess 2450-2550 tops. On a top Athlon or PIV maybe 2600-2700 tops. Terry
