Preflop is loose by Doug. But on the flop he goes crazy, he has so many gutshots, backdoor hearts, hands with one overcard, or even 45/42 have better backdoor potential. It is hard to come up with a hand that is worse than 65o on this board. Doug literally always advocates folding the bottom of your range to a reasonably sized bet, so what is he doing here. Was Doug on tilt?

Turn check seems reasonable. As played, river is a good spot to bluff since he has a diamond blocker but he doesn't block any straightdraw.
