First of all, I think you should bet the flop. However, checking certainly isn't wrong. After you get raised on the turn I think calling and checkraising a non counterfeiting river is the right play, unless, like entity said, this particular player has a tendency to freeshowdown raise. Also, this may sound crazy, but against alot of players I will 3 bet the turn and STILL checkraise a good river. As most bad players who have AA or any king cannot help but bet the river and then pay off out of spite. Definitely not saying this is always or even usually the correct play, but something to think about.

Also.......this player will limp K3 suited UTG. You do not have to describe him as "a tricky postflop player, who plays too many hands" or whatever. A simple "f'ing horrible" would have done just fine.
