I don't know about check/fold on the river but I don't know what else to say not having been there. In the moment, I'd go with my gut and live with the results. I'm not thrilled about the flop call because you're stuck in the middle and can't be sure of what you want to hit. As it was, you got the card that guaranteed the good player wasn't on the nut draw and still found yourself in a tough position. Given that you got to the turn, I agree wholeheartedly with your lead and I expect the good player to go away most of the time. When he doesn't, I expect he has a better flush or a set and I expect the set to check behind on the end, assuming he also views you as a good player and not a donk. If he thinks you are a donk, he can value bet a wider range.
