I think I'd bet a little more on the flop to charge the draws that may be out there to draw, maybe 100 or so. That said, I actually think there aren't that many reasonable draws out there - JT already got there, we have the A
so the Ax soooted donks won't be there. We're either way ahead or way behind anything else other than a gutshot broadway-type draw (which is less likely because we have two aces) or lower SCs.
Because of this, I would also bet the turn as the turn card is unlikely to have changed anything. I think you can make a solid value bet here.
As played, on the river, I think checking is OK as Jx just got there (hence the reason not to give a free river card!) and I am definitely calling the river bet.
