5/10NL vs. known professional

[pocketdueces81]

Villain has $1650 and is in the BB, I have $1400 two off the button...@ fulltilt 5/10NL 5-handed

UTG Limps, I limp w/ 9c9h, button folds, both blinds call. I dont raise here because I will get paid off if I hit a set

FLOP 2c 8c Kh pot=$40

SB checks, BB bets 30, I call because I have the 9c and want to hit a set.

Turn 9s pot= $100

Sb bets 100, I raise it 300 ....sb thinks for a while and calls

river 4c making 3 to a flush. pot=700$

villian bets out 350....what would be your next move?
