I'm curious why you didn't bet the flop? Other than that, given your flop check you played the hand fine. Also, I disagree with those saying the button is going to check behind with a queen. When its three handed, the calling ranges greatly decrease. Of course it is entirely player dependent, but the majority of opponents will bet river with a queen. Thus, if they have a queen they most likely bet, and will have a hard time folding the river check raise. whereas if you lead out they will most likely only call, even with a strong Q, and if they have A8 or some oddly played pair they will fold. The only time I would lead out is if villan never bluffs river, or you are almost certain he has something decent.
