No reads or history except he's playing without a full stack. On the flop I want to keep his range wide as he can have all combos of 77, T9 (plus the 1 88) as well as other 2 pairs and maybe some top pairs, potentially some bluffs also.

By the river I doubt he's bombing away with KJ, QJ and 56 draws came in and I think my range is all 2pairs, sometimes T9 but very rarely and sometimes a set but that's also quite rare and also some overpairs (since a lot of my range is Jx I think KK is too strong to fold).

Is river still a call vs this line and sizing? I think it's near the borderline from a GTO perspective, and I also think that in general people are less aggro than they maybe should be bvb (population read, may be wrong as I haven't played too much zoom). Should I always be folding 1 pair on the turn?
