Yeah there are definitely few value hands V has here on the river. It's possible that V could check a set on the turn tying to be tricky, but V does have a fair amount of flush draws here(Slightly less combos with H having the Q
). If V is competent she might realize that turn is a bad card to barrel since Hero's range is mostly Kx in this spot and thus be more weighted toward busted FD's. Also, I can't imagine her playing Kx this way as those hands would mostly call flop. It would also be pretty unusual for V to try and turn a hand like 8x into a bluff but I guess that can't be ruled out since she is known to show random aggression. I think it's close, but I don't mind a call here. Of course, I probably fold the flop as well.
I think a turn bet is pretty useless since it folds out her air, and rarely gets a better hand to fold. I mean maybe she folds 8x but she might not even have that hand with her range. It also allows her to re-bluff us if she decided to shove with a FD.
