25nl KK versus lag

[vixticator]

BB is in a lot of pots, 34/21/3.5, about 70 hands. He seems to bet against me an inordinate amount of the time, stealing BVB quite a bit. I think this is second time I raised UTG, he folded first.

This flop bet doesn't mean a whole lot, maybe has an Ace, maybe not. I didn't like the turn card a whole lot because thought he would c/r if I bet there quite a bit. River is a nice healthy bet so I don't really know what to do, my first thought was this bet is for value... but after I check turn it could be ATC too.

Fold river, call? Bet turn? Fold flop? Raise flop? Need a better line.
