The table got short so I limped in with the hand and figured it was less likely the straight was out there. I was gonna slow down but picked up a backdoor flush draw and no one raised me still. Who plays this hand different?

I can't believe he didn't raise with the flopped nuts and a redraw to a higher straight. he should have at least done that on the turn.

Yeah, your opponent was a moron. Think you did fine though.
