Hand 1: c/c turn is a fine play. I check/fold river a lot because you don't beat much that villain is betting, especially this one.

Hand 2: Probably call because of odds and expect to be beaten by a better K very often. A raise would be nice to get him off this, he's so scared of the Ac...though he's a calling station.

Hand 3: Against this particaly opponent I am calling preflop. Against a standard one I like your raise.
I'm probably calling down because villain is retarded, but you don't beat a lot and folding river can't be too bad.

I don't really mind playing KT to steal some blinds. But keep in mind your position and the players behind you. You don't want to be in a hand with calling stations or maniacs with a marginal hand as KT.
