I think calling 3rd is fine; folding might be a little too weak/tight. Only problem is that it might lead to sticky spots if both you and Villains (esp Seat 7) catch good, which is what happened here.

I'd play it all the same way. Betting 5th and 6th are automatic, having caught great cards and trying to get everyone else to fold. I'm surprised they both called on 6th.

I like the value bet on the river as well. You're not getting raised here (unless he has a straight or better) and he's going to pay you off with a lot of hands, seeing how he's made it this far. Most likely he's got Jacks up.
