I like his vlog, but I also agree that fold equity is prob a bit overestimated here after the turn bet. Unless I missed it, I don't think he addresses the possibility that villain could have stuff like J

type hands as well. When we hold red 88 I would think there is a good chunk of FDs in villain's x/r flop + bomb turn range, so that should factor into how often we should think that we can reliably bluff on heart rivers (although to be fair, it also prob prevents us from losing the river bet on those bluffs since the OOP villain will just likely be shoving the river himself).
