Hi Wilfried,
I believe it is not a 100% clone. I do not have both machines to make a test to see if they answer same way but going into this tournament could tell if they are 100% clone.
I dowonload chessgate client yesterday but they still have not send me the password. Since i am in the city of Puerto Ordaz i can play sometimes on 22:30 Berlin hour (Mon-Friday) or on some weekends from 14:30 to 22:30 (Sat-Sun) Berlin hour.

best regards
Ricardo
