with given info i don't like this. he has posted in the past week or so that he can make big laydowns but you sound like the kind of guy who he's not going to give credit for a big hand here, and the kind of guy who might get a little fps/spewy and turn a hand with showdown value into a bluff. this is key because your range has a ton of such hands, plus 89 which missed.

his range on the river is probably overpair/flush/bluff/maybe good 9, all of which are probably going to call.

also as far as handreading goes from his perspective a flush would bet the turn some % of the time, a set is realllly unlikely given flop/turn (and pf to some extent - you might 3bet 66/99 a lot of the time as you indicated in your post)

yeah i just dont like this bluff at all.
