Alright Im pretty sure I know the answer to this.
Early in my playing time no reads on villian. Button seems a bit aggressive so far raising preflop quite often.

Pacific Poker ($200NL)
Hero is SB dealt [Ks, Kh] ($198)
Button ($316)
Villain (CO) ($166)

Preflop:
UTG folds
MP folds
CO calls $2
BN raises to $8
Hero Reraises to $18 (Should have went to $25)
BB folds
CO Reraises to $166
BN folds
Hero...?

What do you think?
