We play sixty-six much here in Russia too!)
It seems that I have found some kind of a bug. Sometimes at the beginning of a new deal, bot won't move, when it is supposed to, and there is no way to resume the current game. (The new game can be started though)
I have kde 4.12, Qt 4.8.2 on Kubuntu 12.04.
Anyway, thanks a lot! - Jan 14 2014
