Definately do not raise preflop. K-high is not good enough to show down, so you don't want to start it off with a raise (unless MP2 and CO are particularly terrible and you want to isolate them).

I prefer a fold on the flop here, as its not unreasonable for pf-raiser to hold a higher club (AA,KK,AK) or a pair that beats you. I really don't think you have enough outs to justify drawing here (your straight draw is weak because of the texture of the board, and your flush draw is pretty weak too, given the action that you've seen).

Given your flop action (which you may have had a good reason for), I don't like your turn call against the flop check-reraise. I think that's the time to dump this hand. Your river call is mandatory given the way you played up until then.
