blinds 10/20 everyone's stack close to 1500.
I'm BB with QJs. Raised 3.5xBB by CO, Button calls SB calls, I decide to call hoping to hit a straight/flush.
Flop comes QQ9 rainbow, I decide to check (slow-play, not too afraid of any draws out there; CO raises to 90, button folds, SB folds. I reraise him to 300, he puts me All-In.
He turns over 99 which holds up.
Should I have played that any differently? Was a value-bet really necessary on the flop? And even if he re-raised me once I'd put in a value-bet, could I really have let that go?
I have no reads on the opponent as it was quite early in the tournament.
