$2NL or $10NL (don't know if there's really a difference..) Assume no real reads.

Have AK, AKs, AQs, AQ, AJs, KQs... standard raise from position PF. Get 1 or 2 callers. Miss the flop. Board has no obvious draws, and I am unimproved (just overcards w/ no draws). I c-bet for 1/2 the pot and get called. Still unimproved on the turn (and no obvious draws completed on the board). Either checked to me or OOP so bet first...

Should I bet again for 1/2 the pot for a second barrel? Or check in position for a free card (and hope to improve) or OOP (and fold if they bet into me)?

Did a 5K hand session review yesterday, and I think I'm leaking a lot of BBs by double barrelling unimproved overs without any draw to back them up. Average hand costs me 3BB (PFR) + 5BB (Flop Cbet) + 9-10BB (Turn bet) to end up with nothing on the river. Sometimes I luck out and they fold to my Turn bet. More often they call and then bet into me on the river if I check unimproved.

I know there are no "rules"... but don't want to be a spewtard either... In general, is it better to get away from unimproved overs after the flop or at least bet thru the turn and dump if unimproved on the river?
