Was the PF raise as bad I make it now? I don't even think I've ever raised K4s before. The table was really tight, folding blinds several times. I had a conservative image and hadn't been very active on the CO or button, let alone any other position. When the BB called I knew I was probably an underdog. On the flop I bet out as I thought it'd be too suspicious to check behind. The CR concerned me, but the only hands that fit had a K, so I pushed.

Did I go wrong PF? Thats the only place I think I erred. I think calling PF just makes it a tougher problem. But maybe I "flopped" on the flop as well.

If I check behind on the flop, the turn is an ace, he bets out and I raise. I wouldn't have put him on AK then because I would've imagined AK re-raising my potential steal attempt. Also, I would've kicked myself for letting him catch for free. KK could've also just called PF, but its unlikely that KK would CR such a nice flop. The only other trouble hands I can think of are 66, and less likely 44. The most likely hands at the time seemed KJ or KQ.
