I too would check raise the flop. If the solid 2+2er on your immediate left calls two bets cold, the only logical hand he can have is 99 or QQ-AA (doubtful he calls your UTG raise cold with AJ, in which case you are only playing for a split). If ABC then 3-bets, you must fold. If ABC calls, you also call. If A or J turns, you bet out.... if anything else turns, you can check and fold safely.

If he three bets, you can be pretty sure you are losing. Call to hit a 6 outer (J or A) on the turn and bet out if you do.... if you do not, then check and fold the turn.

If 2+2er folds to your check raise and the ABC player three bets you, proceed the same way as above... call in hopes of your 6 outer with the pot laying you 14-1 odds. If 2+2er folds and the ABC player calls your check raise, you must bet out the flop with any card hitting.... if you get raised at that point (and the turn was not a J or an A) you are almost definitely beat and can fold.
