Hero ??

Okay one, I'm not sure I like the squeeze so much as MP1 is raising UTG and thus probably has a strong range, but can I really call or fold PF here?

And two I'm having trouble figuring out a range for CO to call then call a 3bet. Something like 66-QQ? But then that doesn't make much sense as you would expect him to 3bet MP1 with like TT+... But then again maybe he elects to setmine 66-QQ against MP1 because he perceives MP1's range as strong?

And at any rate I don't think I cbet this board because I'm likely to get a hell of a lot more calls than folds out of the range I came up with...

Thoughts?
