Could I have played this hand any differently, could I have gotten away from it?
Should the other guy really have made the call of my raise preflop?

You got 1/3 of your stack in with the best hand, then the rest in at about a 50/50. That's about as good as you can hope for.

Villain's call preflop is pretty light, that is a very raggy hand. But heads up if he hits top pair or better he's golden (usually).

When I got all my chips on the flop, pushing into him, I didn't know it was 50/50. That looked like a perfect flop for me. In fact, I was praying he hit his king with a good kicker.
But KingFour, how could I have known? KingFour is so random, there's no way I can put him on a hand like that.
