In other words did you get the >autoplayer to run under Windows? Hi! Unfortunately several testers have problems with autoplaing Century4. For me it works excellent,only one stop when C4 missed the first move from Shredder5. It also seems to work good against CB-programs a 30 game blitz-test against Nimzo7 with one 1 move game and one game that Century4 didn't saved. I have also played about 200 5-10 min games against Gambit2 (Chesspartner) and Shredder5 and the results without doubt indicated more then 35 elo improvement. Yes I use WINDOS and 200mb hash including the a and b-parameters. I save the match in "Rebel-format" so you can check it after it is finished. I have followed a lot of the games and everything including search-speed and autoplayer seems ok. Bertil
