I am not very good with the lingo, but basically i was watching him the entire game (he was easy read and chip leader by a good distance), he would limp in any position, very loose player with wide range and would only check/call while chasing or with an underpair.
He Would raise with only very good hands the better the hand the more he raised. He took out some very easy plays early on with some all in action on the first few hands, so in my eye's the rest of the game he played the same all the way through and only won his chips through 'luck' and not good reading/plays.
I had played a very very tight game with not alot of big hands early/mid game, so with this in mind and having a good chip stack when we came heads up i changed my game alot in this position (being aggresive with nothing to limping in with good hands for setups) and he had no idea what my hands were and couldn't read me at all.

P.S Hand 13 was probably my best play to help win this SnG :P
