does anyone actually study poker seriously while playing
Yeah, not really. While playing, the only thing I’m “studying” is whether the game is even worth sitting in. Live $1/2 with a $6 rake plus $1 promo drop, that’s 3.5 big blinds gone every decent pot, brutal. I used to waste brain cycles replaying hands, meanwhile I was in a bad seat at a dead table. Fix that first. The rest can wait till you’re home, tbh.
