Villian is a 68-18 player so he got some aF, but he is more passive postflop tho. My thinking was like when the jack comes on the river it's very unlikely he got a jack it's unlikely he got a made hand as I block the nut FD. So he is quite polarized to either a busted FD a second pair like(77 88 99 TT or a jack don't ever think he got a set on this board he wouldn't c/c it he would either donk it on flop or check raise it.
