5+0.5 Easy fold with KK early (postflop)?

This is about the fifth hand of a 5+0.5. t1500 starting stack, blinds 10/20. No reads on anyone, everyone has about 1500. I'm dealt KK in MP. EP guy limps, I make it 100, guy to my left calls, early limper calls. Board comes down 456, I bet 200 into a pot of 330, both players call. Turn comes a 2, EP limper pushes. This is an easy fold right?
