put him on a hand, please (200NL)

[joseki]

CO is 17/4/2 over 575 hands, I had thought he was reasonable postflop. The rest of the table is too loose and too passive.

Effective stacks: $198

Preflop: MP and CO limp, I call in SB w/ K [img]/images/graemlins/heart.gif[/img]8 [img]/images/graemlins/heart.gif[/img], BB checks.

Flop ($8): Q [img]/images/graemlins/heart.gif[/img]8 [img]/images/graemlins/spade.gif[/img]4 [img]/images/graemlins/heart.gif[/img]
I check (planning to raise), it checks around.

Turn ($8): 5 [img]/images/graemlins/diamond.gif[/img]
I bet $6, folded to CO who raises to $12, I re-raise to $56, he pushes to make it $194????

I regret my flop check. Should I have just bet out for $8 or something?

Turn: in general, is re-raising spots like this bad? After he pushes I'm really confused. I can't really put him on a hand, but I can't really call either...
