Am I In Trouble With AK here?

[DrWily]

10/20

laggy couple of hours of poker since I sat down.
Image is tight. Only showdowns have been the best of it.
Villian is on button. Has been running over table flopping monsters w/his garbage.

I open UTG with AKo.
UTG+1 nit cold calls
Folds to villan who 3 bets.
Blinds fold, I cap.
Call, Call 3 to flop

Kd Qc 10c

I bet, nit call, villians raises
I 3bet, nit folds, villian calls.

Turn 9h

I bet, villian raises

Am I worrying too much about a donkey on a hot streak?
