2nd pair gets donk bet on turn

UTG is a rich middle aged asian guy (actually, I'm the only white guy at the table) who plays 75% of his hand, chases to the river with 3outers, calls down with any pair, and autobets all the way if he raises pf. He rarely check raises. He'll try to steal if checked around to him on a late street, and he likes to donk scary flops. He's having a good time even though he's down five racks.

I'm card dead. The few times I've raised pf, I've had to check/fold the flop, or fold the turn to a donk bet.

UTG limps, two more limpers, I limp K [img]/images/graemlins/club.gif[/img]T [img]/images/graemlins/club.gif[/img] in MP2 or MP3. 7 to the flop for a single bet.

Have you ever seen him bluff into half the table? If not, it's probably a fold. I doubt your good <10% or so you need here.
