in fact the whole hand was incorrectly played.
1st. you called having unconnected King high with bad kicker pre flop.
2nd. you chased your straight draw on flop by calling one/third of your stake.
3rd. you risked your whole chips on the turn by calling a naked king on a flush drawing board.
4th. you didn't respect your opponent hand when he raised preflop on two players having position on him.
5th. your opponent can have easy A's or easy better King than you or even an easy set postflop .
But maybe you where multitabling and that gives you an excuse.
