KK first hand of ME qualifier on tilt ($300) TROUBLE

[Dawg24]

title gives most of the info...I am in small blind with KK blinds are 10 and 20. start with 3000 chips.

UTG raises to 60 and MP3 raises to 440...

folds to me in sb with red KK...I just call...thoughts??

UTG folds...to the flop..T910 in pot

Ah Jh 10s... my thoughts are he was protecting a pocket pair with that over bet and this cant be a good flop for him unless he has (Ak, Aj, A10, JJ, or 10 10) and I have doubts of Aj or A10 with that bet. So I lead out with a bet of 477 to see where I stand...he waits about 2 seconds and goes all in...WTF???

so I think about it and cant come up with much I beat...I am guessing 10 10 or JJ or Ak so I fold even though the pot was offering close to 2-1. I think fold was correct but was it? How close is it?
