Stress??? Oh, Yes, it's part of the game, I think it all depends on the specific person, either you get stressed and it gets in the way, or you can keep yourself in hand, despite the circumstances. And this is true for life and for poker. I'm more stressed when I'm not raising the stakes, but when I'm playing many hours of tournaments. When you spent 8-10 hours, played carefully, built up the stack, and then you can miss everything!!! At such moments, the pulse is off the scale and it is very difficult to make decisions. At such times, I try to ignore the tournament and its stage, the size of the bet and the opponent, and imagine that this is a normal hand, a tournament of one hand.
