[flatline]

Hey everyone, my first post here, been lurking for a while. Great site. This is a hand that occured in Tunica that has been bothering me, just thought I'dpost it here and see what everyone thought.

The table was pretty tight, almost everyone seemed to know what they were doing. However, it was pretty passive pre-flop and most hands had about 5 or 6 players seeing the flop without a raise.

flatline (me) is in the CO, Real World(that was what we called the guy) was in UTG+2

5 people call pre-flop, flatline has (2d,2s)

Flop comes Qs, 9d, 2h

Its checked to me, I bet, Real World and 2 others call

Turn comes Kc

Its checked to me again, I bet, Real World Raises, I reraise, everyone else folds, Real World caps, I call

River comes Ah

Real World bets, I raise, he reraises, I call

I guess the title already revealed what happened, so I'll go ahead and say he had QQ

What is my mistake? I think maybe I should have just called the river, but isn't that really weak?
