IMO... U acted strong preflop, I think since I have a such a weak hand KJ, that I might of only pushed it to like .35 - .45; but thats beside the point. Since you acted so strong on the button when the flop came out rags u should of def bet, especially becasue they all checked around to u. Worst case scenario you get check raised to which you make a simple lay down.
When the King came on the turn this is a scare card in my opinion since the Villain came right out betting, He could easily have something like K 10, 33, 44. He prob doesnt have anything stronger than that because he more than likely would of raised preflop with KK, QQ, AK, ect... If you would of raised post flop then you would of at least known where you are in the hand. Also you would still have control. Once you call the turn you are giving away all advantage that you have in the hand. If anything you could of raised the turn but I think since you Fucked the hand up that bad...jk... that you chalk it up as a learning experience and dont make the same mistake next time.
Just a thought but I think when the King hit he prob had u beat, and that was def a good laydown on the river. So altogether u lost $2.35 which you prob would lost no matter what that hand when you decided to play the KJ in the first place.
