Overqueens in a big pot

[Azhrarn]

Early hand at a table. No individual reads, but the table seems looser than average, normal aggression.

Preflop: Hero is UTG+1 with Q[img]/images/graemlins/spade.gif[/img], Q[img]/images/graemlins/heart.gif[/img].

Here's where it gets interesting. Once he raises, I think I'm solidly behind MP2's hand range here, and the others are coming along for the ride. Even if he's semibluffing with AQ or AK, he's got a number of outs against me. Anyone like a 3-bet here? I decide to call and see what the turn brings.

SB checks, UTG checks, Hero...

So what's the best plan of attack here? Include a river plan as well. My instinct was to check-call until I got a clearer sign that I was beat, but I suspect I often default to that line too quickly. Thoughts?
