From your description, it doesn't seem likely he has KK/QQ/AA/AK because of his min-bet pre-flop. KQ or KJ seems reasonable, although he'd probably be more aggressive with the former. Maybe QJ/JT/KT. Obviously he doesn't have air. AT doesn't seem likely unless he's getting desparate to try and stack you.

You aren't worried you're behind are you? I would worry about an A or a 9 that could possibly help an OESD.
