HU is such a finnicky game, with all kinds of dynamics and money swings. Best way is to learn from people who had success at it. If you want to spend a little money, Spenda and AApoker have some very decent videos on grinderschool going over some good concepts, hand reading, exploiting etc. Or just take $30 get a 1 month subscription to Leggo and study at the church of aejones (that guy is sick nasty at hand reading).
