weird KK line

[howzit]

i took this line w/a player I've never played w/before.

we're playing 5-5NL live and it's getting late into the night so players aren't gambling as much. So far, villain is playing straight forward and I am driving 90% of the action. I am running good and playing good. I am playing fast but nobody has caught me bluffing.

5-5NL live, 6 handed.
Villain (MP): $1100
me: covers

I make it $35 w/red KK up front. MP, button, and BB call.

Flop: ($145) Ac-Qh-3d
checked to villain who bets $100, folded to me, i call quickly.

Turn($345): 9c. I lead for $250 planning to push on the river if he calls. But fold to a turn raise.
