Depends on villain, if they do that mini donk crap I tend to do what you did when I'm in position. When they call I think your in trouble. That K hitting the turn either helped you a lot or is going to get you into a jam.

What did you think he had when he goes from a 25% of pot flop bet to a 80+% of pot bet on the turn?

Edit: looking at stack sizes, I think you should play small ball as was suggested above. I didn't notice villains half stack originally.
