I've never really played 2NL but 10/8 seems a bit tight. ATS is only 17% so I'd say open more hands in LP. Raise with A8o from CO and you can be sure someone in the blinds is going to call you with much worse very often. You probably play most hands very face up but considering the competition, they're not paying attention anyway. What is your win rate? Because if you're not making a decent bb/100 playing 10/8 @ 2NLFR, then something is wrong.
