QQ barf hand

[obi_wang]

live $3/6

just sat down, only saw one hand of villain who just took down a pot with top pair, betting it solid. didnt seem like a FPS-type of guy, but not a real reliable read, either.

neways, a couple early position limpers, villain in late position raises, button calls, hero in bb 3-bets. 4 people to the flop.

Flop: K 8 3

I lead out, 2 callers.

Turn: 10 (no flush..)

I check, early position checks, villain bets... i look at him for a bit and just feel like he or early position really has a King and dont feel like paying two more bets to see it. I fold.

River: Q

check, check... villain had two 9s and scooped pot.

whats the correct line on this?
