King of Vegas - Matusow eliminated in texas holdem

[restrikt]

Evelyn Ng played terrible tonight... going all in with second pair, after a bet by a tight amateur? That was terrible... and she sucked out on Matusow big time in the heads up sudden death match.

Matusow was playing great until going in with 86o and goign up against Evelyn's KK. Why was Matusow moving in so much pre-flop, when he can easily outplay Evelyn post flop?
