It doesnt need to be a complete bluff for us to call here. Often our opponent is going to have a pretty random hand here and think that there Qh or something else is good and push. They also could be making a strange bluff which adds to our equity here against their range. We really cant be folding the second nuts to a PSB on the river without much much deeper stacks and a much better read on our villain.
