I don't have a good enough read on the villain to figure out exactly what his check on the turn means. If the villain has been paying attention to me at all, he should know that there's a chance I'm bluffing this river. Unfortunately I don't know how much the villain has been paying attention, so....
I feared 22/33 but also thought that 9T, JT, QT or KT might play the hand the same way.
