i agree with dk, i would call the last raise and see a flop, it was what, 330 more into a pot already over 1k, even if you put him on AA, still have implied odds, as if the 1 in 7 (think thats what odds are of flopping set with pp), you probably get him allin and have over 2k behind , so over 5k for only 330 more, idk, i can't fold KK pre ever.
