Pre-flop: (9 players) Hero is CO with K K
3 folds, MP2 calls, MP3 folds, Hero raises to $10, Button raises to $25, 3 folds, Hero calls.

Flop: 7 6 3 ($55, 2 players)
Hero checks, Button bets $35, Hero calls.

Turn: J ($125, 2 players)
Hero checks, Button bets $150, Hero ???

MP3 was very bad (34/2).
Button was (20/2/2 and 0% 3bet over 120 hands). I've seen him call a C-bet IP on low flop (with JJ) and bet 2/3 (and then min 3bet) on turn when he hits his set.
I don't think he 2barrils here with less then KK+. Comments?
Thanks!
