I just started getting interested in HUNL cash and have started a rivarly with my roommate, whom I've been playing a lot of live heads up with. My question is, since we're both beginners, what are common leaks of beginner players in HU? As we play live and I don't have a HUD, things I've noticed are: value heavy preflop 3bets and a value heavy x/r range. Also I suspect he c-bets too frequently. Are there other standard leaks in beginner players, and how should I be looking to exploit them?
