I realize I should be value betting river here, but I checked cause this player is super snug and not active at all. I think he will only call check/raise with sets, 2pr, straights, and maybe, but unlikely KQ.

Most players don't realize they have are hard time finding bluffs here, and therefore, need to turn pairs into bluffs.. Do you think the fold is okay? I looked back and said, well damn I proabably should call for that price and fold for larger, but I also think people bet small with the nuts here because I checked and it shows weakness.
