We have no idea if this player is capable of the semi-bluff raise on flop w/ a flush draw. I would think that our hand is good here more times than not, so I'd just go for the c/r and call down a 3-bet. Obviously, bet out on the river, if called.

He could also just be raising a pair of 9s on flop or trying to be a "tricky bastard" w/ a good pocket pair by doing the LP limp. Maybe he does have a set or higher.

I tend to like to get extra bets in, but I'm unsure as whether or not this is good here against an unknown.
