Well, in Minsk, about ten games were played, in the format of a "country cottage." The motivation was financial. And there were cards, chips, and plenty of alcohol. I don't see a problem here.
But playing in a club during the summer is definitely a problem - sitting in a cramped, stuffy club when there's fresh air, sunshine, a river, and attractive girls outside. It's difficult not only physically but also psychologically.
