OK, I got Fritz connected to chessanytime.com
I created in the desktop a new shortcut to Winboard and renamed it to "Winboard Fritz 8 chessanytime"(you dont have to do this but it avoids confusion in the future), then right clicked on it and selected properties, then I modified the target to be as follows:
"D:\Program Files (x86)\WinBoard-4.2.7\winboard.exe" /zp /ics /icshost Chessanytime.com /icsport 5000 /icshelper=timeseal /fcp="winboard232d.exe -pipe"
Note: The whole target it is in the same line, but due to this window restrictions, here might be shown in multiple lines. Also, notice that my winboard is in drive D and not C, and also because I am running windows XP 64 instead of 'Program Files' is 'Program Files (x86)'
So you should enter the correct path to winboard.exe
Ok, after the shortcut is created, launch your chessbase program and follow the usual steps to connect to Yahoo and when you get the window that says "Waiting for connection" then double click the new shortcut. And viola!!!!! You should be connected to chessanytime.com with your chessbase program ready to kick some ass. Do not forget to switch to "Two computer match" mode and uncheck the "Master" option.
Everybody knows I do not like cheating on human users, so, if you are going to register, I suggest you pick an ID like xXx_Rybka_xXx,but of course, that is entirely up to you.
Enjoy,
