You don't gain much by raising the flop. You can't make him fold a hand that is going to draw out on you, just call and perhaps raise the turn. You could even wait for the river on this one if you were so inclined.

Given the way you played it... don't call down. If you have enough equity to call, you should raise. Why give him the free 9 outs for half the pot? Very few players will bluff 3-bet in this spot, and if he does, tip your cap and push him the pot.

good luck.
