I would actually Bet/call this turn. Once the nine hits, your hand is not strong enough to checkraise IMO becuz of the time times you get 3 bet by 9x, a hand the villain can easily have given the preflop/flop action. Plus it is possible, but I'll admit rare, that the CO will check behind if he has a hand like JT, Two spades, or a hand like KK that he intended to trap you with by just calling preflop. I realize that most people would not take a free card in this situation but nonetheless it is a factor that leans me towards bet/calling this turn.

Also, I wouldve 3 bet the flop in this situation just becuz there are so many turn cards that may lead me to cancel my turn checkraise strategy.
