I'm up against AA, KK or a bad player right?
Good fold?

After the flop, you've got TPTK. I'd actually be more worried about someone making a straight than AA or KK. Although their raises aren't really consistent with that. Difficult to say without info on the other players at the table, but I would have stayed in, esp in micro limits.
