Does my line here seem good? Have just sat down at the table so I don't have real postflop reads on the villain, he's been about as loose and passive pre as your average 5nl player.

This is a spot where a while ago I think I would have made a small river bet with the hope of getting thin value out of a weaker K but recently I've started to think that they're ahead way more often than I'm getting any more value. Figured he's not got a lot in his range he can bluff with here either.
