I am leaning towards a river check/call. It seems he will bet the hands he will call a bet with everytime, while he will usually raise your bet only with a full house. Also, you may get a bluff out of a busted flush draw.

Pushing here is equivalent to hating money. Giving as played, I probably call because I tend to convince myself he is playing trips retarded or doing an elaborate bluff but from your read this doesn't sound like the case.
