$100NL 6-max @ FT

guy completes the SB. i check in the BB w/ [8h]. sometimes i raise here. this time i didnt. villain seems loose/bad but not many specific reads.

flop: [7h][2c]
pot: $2

check, pot, call. weird 'cause he's folded the last 3 times i've done this to him. maybe he's on a draw?

turn:
pot: $6

he leads $4, i call.

river:
pot: $14

he leads $12. my action?

also- how does this change if the river is the ?

I'd raise to like $35 and fold if he shoves.
