I'm not one to play split pairs often so I'd probably fold 3rd. I think this hand is a good example of the kind of dangerous situations you can get into.

I think the bet on 5th is fine. It's unlikely Seat 7 has a straight but he'll play it strong as the only one with a possible low at that point. 6th street is a real problem. I highly doubt you're losing anyone here with a reraise although he may have led out in order to have you face two bets. I suspect you're probably ahead of Seat 3 as it's unlikely he has trips or a flush with all those dead spades. Since he didn't 3-bet, you're probably ok here.

I would raise the river, I think he might pay you off with a lot hands you beat. Nice catch.
