There is no reason to be so risk averse with KK that you push preflop here or that you raise half your stack. Getting two people to put more money in preflop when you have kings is fantastic. You just got unlucky that the flop contained an ace.

I would just check behind on the flop because it's too likely that someone has an ace and won't fold. The turn is actually good because it makes it more likely that your hand is good. If villain bets or pushs the turn you have to make a tough decision based on how you think they would really play a big hand here.
