villain was 59/27/3. He had been stealing my blinds very often. Once I tried to fight back (i.e. 3bet PF and bet flop), but he seemed to have something. The only hand I'm afraid on the turn is 55, however, I think that with top 2 pairs on flop and after the K I should take the risk of stacking off to 55, while he could have hands like KQ/KJ/AK/TJ even K8 or K9 or a diamond flush.
Would you call river?

Shove turn. Don't make a habbit of picking on LAgg's blinds with crap hands.

As played, I call the river. You can't just assume a set of 5's here, especially when you flop top two vs a maniac who runs 59/27/3. If he shows you a flopped str8/higher two pair/set meh and reload. His river bet is scary because it seems like he loves his hand (flopped straight) :S, but i don't know how you can fold this against this villain. I probably even shove over his turn bet.

EDIT: Also what fnord said, when you have a player or two to your left with a vpip of 50 and above, don't pick on their blinds with marginal hands.

i don't think you can fold here though you only beat a bluff (unless this lag overplays top pair) . I feel like i keep repeating what fnord says, but I think you should fold turn or shove turn with the draw heavy board and only 100bbs deep.

Odds are too good to fold but I like the turn shove as well.
