QQ and TT aren't so likely mathematically (only 1 combo of each is available), but you do have to start worrying about those hands at some point.

I think AQ is likely for CO. If that's what he's got, MP3 can't have QQ. MP3 could have AA/KK (which is 9 combos if CO has TPTK).

Ugh. I don't know. I kind of want to 3-bet. I think you're probably ahead of CO, and the fact that he 3-bet the flop makes MP3 a little less likely to have you crushed. Plus, you're getting 2:1 on the bets that go in, so long as CO doesn't fold (I guess he might, though, if MP3 caps).

What I'd probably really do, though, is get scared by the action and call. And maybe that would be sensible. I'm not sure.

By the way, the preflop iso-raise is a little light from MP2, for my taste.
