First is a check because villian called 5th with two babies and a queen showing. this means he probably has 4 cards to 6 high entering the river. As I said before, he knows you have 8 high in hand 1. In hand 2 he called with a 9 on sixth street. This means he probably believes you have not made 8 high yet. Betting here gets called by 9 highs and 87 highs that think you never made it. Yes 7 on 5th changes river to a check. I think that villian would bet 7 high on 7th street though.
