TPTK against loosey goosey

[Sam T.]

Party $15+1 - Villain just LOVED his draws, and clearly had no understanding of pot odds. He's nowhere near good enough to raise this flop with KK, and there's no way I'm going to give him credit for a five. What's your response to his raise, and how do you play the turn?
