I haven't read the other posts yet.. but my two cents:

Bet the turn harder, almost pot. All the hands he called the flop with have now improved (where improved means they either now have top pair + OESD, or some pair plus insider or some two pair). All of these hands will call a pot size turn bet.

On river, it's VERY possible our hand is behind. But it's also very possible our hand is ahead. Were you going to c/c river? If you were planning on c/c, then b/f is just way better. Almost his entire range has some piece of this board and some showdown value so he's rarely rarely betting worse on river, so you can't really induce. Just bet 2/3 pot, let him make a mistake, and fold if he shoves.
