KK late $10 180...as chip leader facing loose big stack push on flop

[ssnyc]

don't see reason to check this flop...if I had AK and missed I would bet it same (maybe a bit less) and villan should know that...would he push with any pair or a flush draw if he puts me on an overbet C-bet steal? I have what looks like a great flop for KK with a villan who doesn seem to mind getting nuts...I need a strong reason to fold here even though it is a critical spot chipwise
