Weird river hand

[edge]

5/10 6-handed. I just sat down recently, so less than 5 hands played, but Villain doesn't strike me as good based on his name and other things (I know, weak read). UTG limps, poster folds, I make it 60 with A[img]/images/graemlins/club.gif[/img]A[img]/images/graemlins/diamond.gif[/img] and 1000 behind, folded to UTG (covers) who calls.

Flop K[img]/images/graemlins/diamond.gif[/img]K[img]/images/graemlins/spade.gif[/img]2[img]/images/graemlins/club.gif[/img] with 135 in the pot.

Villain checks, I bet 110, he makes it 275, I call.

Checked through.

Villain bets 175. I have about 650 total left.

Clearly I'm not going to fold. Raise or call? If raise, how much?
