Raise.

You would like to take the pot now (though from description of OM you will at least see 4th street), and barring that you need to find out if you are behind. Since CG is predictable and will fold (A3)3, for example, or (JJ)3, you would like her to go ahead and do that, and if OM is really just playing with three Broadway cards you'll have a significant edge because he can't pair Kings and out-kick you -- he has to pair an Ace, make a running two-pair hand or a straight.

I raise because CG will probably fold and you're in good shape against OM, who will probably call. If CG doesn't fold, you'll know how to play the rest of the hand.
