Roughly how much stronger do you estimate the new version to be? I'm intending to start testing it for CCRL 40/40 during the coming week.
ReplyDeleteHi Abel,
ReplyDeleteThanks for the new version. I would like to test it under WinBoard but it seems to me that it does not accept time controls such as 1:40, only whole integer values. Could it not be fixed?
Regards,
Gabor
Uh, I didn't try that, I will download winboard and have a look, thanks for the advice!
DeleteHi, I'm trying to compile the code. It seems there are some Units (BB...) missing. Please share theme. kind regards. Hubert
