after rereading, i think pot+ size bet on turn would have been better. true you can't rule out KQ and a bigger turn bet would have took him off his draw in most cases. if he's been pretty tight and seems like a decent player most likely he wouldn't chase with only the river to come. However, your smaller bet also did induce value. either way, I think you played the hand well, but deffinitly at the least a call on the river, however in this spot depending on his previous actions I would have probably shoved.
