on the river, any high hand will look you up given previous 3 streets.

flop: i'd bet most of the time, check sometimes. counterfeit protection and backdoor wheel/flush. since you dont' have Ad it can get tricky if you get check raised. but generally, if somebody can't c-bet on that board after 3 betting me preflop, i won't give him much credit.

preflop: depends who's in the pot. but until you get more comfortable playing O8, i'd say stay away from 4 betting preflop unless all 4 cards are working. it's going to cost you in the long run when you start chasing emergency lows.
