Pre: Absolutely fine, folding is too weak and 4betting is a serious overplay so calling here is good.

Flop: Checking is good here as long as we are planning on check calling and not check folding.

Turn: When villain checks back here I would probably opt to bet this street ourselves. Checking is by no means bad, but I think I prefer taking the initiative in the pot.

River: I don't like the bet when the Q rolls off. That Q will have hit villain sometimes for sure with hands like AQ and occasionally QQ, it also makes it less likely that we will get called by weaker pairs such as TT. As played I think I just check call here and hope to induce some bluffs from the lower part of villains range.

I like making a small protection bet on the turn, similar size to what you did on the river.

As played once the Q rolls off I'm probably check folding the river. If he wanted to bluff he'd have done so by now, and will have a fair few Qx combos plus some slow played Kx. I doubt he has any smaller pocket pairs you can get value from, and almost certainly won't bluff 7x 5x at these stakes.
