Only looked at the first hand, but dunno what that guy was doing.. he called quite a high raise with a mere low pp. And without any other callers to boot. I'd never do this. And then the board gives a super obvious winner for a preflop raise that high, and he still calls a raise that is more than the pot.. my god!
(sorry but I don't think I need to look at the rest of the hands after this one)

edit: ok looked anyway

second hand: you chase when your pp misses.

third hand: he got bad luck on the river

fourth hand: pure comedy, he throws himself all-in with the smallest stack on a flop with 3 overcards and 7 (SEVEN!) people in the hand.. haha

Hm, maybe I should go play 2NL after all..
