$1k - Quick checkup - facing a river lead

[Hattifnatt]

Looks like a pretty clear fold to me, he most probably peeled one with something small and picked up a flush draw on the turn.

You had a note that he use to value bet 1/2 pot on the river, but since you look strong and he backdoored into it he decides to make a larger value bet.

I also think he shoulda made a smaller bet with 8h7h.
