If you raise you're most likely against only one of those hands, not both
Quite often you actually take the pot down on the flop. Also in plo that can be in one hand, here you're essentially tripling your money.
I mean it's not the worst option but if the CO opponent is even slightly tilted meaning that he has a looser calling range especially here on the flop than he should (more cards to come so a lot of hands like 98,87,86 maybe that should fold). If CO had a really strong hand, wouldn't he just 3-bet himself? There's 380 raise+290 in the pot, he only has 1500 stack. If pro has a good piece of that flop, he's almost pot committed. No need to get tricky and maybe invite more people in.
Pro's raising range is strong here on the flop, but it still contains a lot of semibluffs which is additional reason why I really don't like giving free cards by flatting also. There's no way that he does this without outs. However what worries me much more is the really awkward stack sizes. By raising you end up committing to a pot where you have to call of the shove. But since CO flatted which I think is actually sign of a strong, but not nutty hand and some hands that he should fold (tilt), there's too much dead money in the pot for me to do anything else but raise/call here.
I obviously don't know these players, I don't know this game. I like folding more than calling.
I hope someone else comments also :/
