I agree bet and shove most river cards. I'd guess his range is something like QJ, KQ, AQ, KcTc, AK, perhaps some other flush draw or maybe a ridiculous low PP that just didn't fold the flop for some reason along with stuff you are behind. Unless you get raised I expect to have best hand on river most of the time, this is the type of player you can get value on every street with this kind of hand...
