Playing K-3 out of position leads to situations where one has to check-call the whole way. You pair your kicker card and there's guaranteed to be overcards on board. You're rarely going to have a powerful enough hand to make any kind of move

That said, I don't like the idea of check-raising the turn. The bettor, by your desciption, plays bad. To me, that means he could have a 6 or a 4 and a semi-bluff raise won't have half it's value, namely, that it might win right there.

I suppose a flop check-raise has the advantages the other posters have pointed out. But then again you don't have anything yet and you're up against a bad player.

I'd have just folded it pre-flop and that would have ben that.
