Flopped a straight, now what (and when to raise/cap the river)?

I think a flop check here is ok. There's no flush drawn and we're not forcing out anyone with a gutshot to the top end or an OESD so the protection reason is null. We have the nuts here and I think checking the flop and leading/raising the turn is good because we might get some more bets out of someone who wants to keep chasing.

If we lead the flop, then lead a blanked turn, we might fold some people out of the turn who would otherwise pay us off if we act passive on the flop.
