how many chips do you start with at ub? it looks like there are a ton on the table.

i would complete pre-flop. there's no need to build a big pot out of position with a marginal hand, especially against a passive villain who may have limped with KQ/AJ/etc.

i could go either way on betting the flop. if he's passive, i like checking because then you can profitably call a bet (b/c his bet means he has enough that he'll pay you off if you hit, and he probably doesn't have a flush draw so, so all 8 outs are good). and taking a free card with a bunch of outs is cool too.

the turn bet is ok but i'd prefer a check/call.

i hate the river bet. if he's good, he won't call without Kx or MAYBE with an 8, and there's no reason to think he has an 8. make a small value bet and get paid off by 2 pair.
