Q9 6-max flop/turn play

I like the flop check-raise. There's a great chance button is taking a stab at the pot with anything - any draw, any pair, maybe even a-high. Your queen is likely good here.

Turn: Tough situation... I hate these ones. Everyone checked a scare card to the button, who could have bet a flush/straight draw on the flop (or had a pair of Kings) that now hit. I think folding would be the right play without a good read.
