Donk river bet, what's my line?

[JeffO]

I'm in the BB with red aces. SB is the donk in question, his numbers are 42/5/1.4 and he is the reason I'm at the table.

Folded to MP who open raises, SB calls, I 3 bet my red aces and MP caps, all call.

Flop is T [img]/images/graemlins/diamond.gif[/img] 4 [img]/images/graemlins/heart.gif[/img] 9 [img]/images/graemlins/spade.gif[/img] SB checks I bet, MP and SB both call.

Turn is the 9 [img]/images/graemlins/heart.gif[/img] SB checks I bet, MP folds and the SB calls.

River is the 3 [img]/images/graemlins/diamond.gif[/img] and now the SB bets. Raise or call? If I raise and get 3 bet what's my action?
