Like the others have said, you aren't really repping a K as much as you are protecting your hand. A lot of the time you simply had the best hand here but no card in the deck other than the 2 3's are good for you. No one is going to put you on a K particularly and you might fold out some weak hands that are beating you. Really the range of things that you'd bet here is very wide given the two rounds of checking. Mostly the only thing you have to worry about is the original raiser having a middle pair that he didn't want to bet into 4 people, but would call 1 bet with.
