Only 9 hands & so far no info

When SB calls flop cbet I still put him on a relatively wide range including sets/76s/ovrprs/A7s/87/A6s/98s/T9s/Ax. When he calls turn, which is a pretty big bet, his range narrows to sets/76s/AJ/Ac6c/9c8c/Tc9c/Acxc. When he leads it narrows again to something like sets/76s.

Sux but donk lead on the river is often really strong hands. For example I would be surprised to see AJ here and that's really what we're hoping for when we call. I almost never see a missed FD here. The thinking is, "If I check, and he checks, I will miss value with my nut hand, so I'll bet". Your bets make you look strong, so why would he bet into strength? Only if he's strong.

Tough to fold though.

Weird hand. No bluff besides 98ss makes sense for him to have. So I guess we have to fold here, than again people at these stakes sometimes show up with weird hand so it might be closer than it looks but I think unless I have reads on him I m just folding for now.
His line is kinda weird/maybe bad with 7x as well because its probably just much better to go for a checkraise vs our line.
