Wow, lots of bad advice here so far.

I'll add mine to the pile of poop.

Flop is fine, don't even think about 3-betting or jamming without a read.

Turn check is fine, it appears he's weak though it might be a check to induce your bet on the river.

River I think bet/fold or check/call is fine for lines -- I tend to lean towards check/call as I think its a relatively thin value bet given the range of hands that call you (certainly appears he has a busted draw). The other thing is if he checks behind you'll have the info on what his hand was so you can make a note which is nice for the next time he raises your flop bet.
