$1/$2 NL live - deepstacks (~300 BB)

Fantastic game. $1/$2 live uncapped buy in game in NYC. 8 or 9 handed...3 bad LAG's who cannot get away from top pair hands and such. Most stacks at the table between $400 and $800.

Villian in this hand has been VERY tight since he sat down an hour or two before. I veiw him more weak tight than TAG. Only hand he showed down was when he doubled through the table big stack with a flopped set of J's against AK on a K high board.

Hand:

Hero (~600)
Villian (~500)

Hero is dealt KK UTG + 1 and rasies to $17 (UTG starddled to $4).

Villian in MP calls as does LP player.

Flop: 6 9 10 rainbow Pot (~59)

Hero bets $60
MP thinks and rasies to $120
LP folds.
Hero thinks and calls $60

Turn 2 (suit not important) Pot (~$300)

Hero bets $125...

Thoughts? I'm not sure about the size of my turn bet...didn't want to pot committ myself if villain pushed, but does it look too weak?

I will post results after some feedback. Thanks in advance.
