BB was loose and could have anything here. Button is unknown. Call this river?

Turn bet is weird, makes me thing he has qq. I guess I call the river, but the turn bet should sens alarms in your head. Unless he is a donk, in which case he could easily have qq or a 6. I guess I call on the river, but I dont like doing it.

You're close. BB folded river, and button shows 66 for quads, MHING.
