Was this hand live? How good are the players?

I never ever fold this hand. At these levels villain has 97, bottom set, or an overpair more often than 99. Nothing you can do . . . I would have gone all-in much sooner than you did.

I personally would have raised from CO with 77. If your raise gets it heads-up, then you can frequently win the pot without improving, and your hand is well disguised when you hit your set. However, I doubt you want to put in a big enough raise to fold 99, so raising would not have saved anything here.
