Actually, come to think of it, an even higher reraise might have weeded out this gambler.
You don't want him to fold. You want people to call with dominated hands.

Postflop I think you both played it well. He leads out thinking he may have the best hand and if he didn't it has a good chance to crack whatever you have. There is no way you can put him on a combo draw like that HU and push him in. Nothing wrong with that.

Note: The way you wrote it makes me think he led, but I could be wrong there.
