I watched these last night and thought he should push quite a bit more, especially in #2 after the calling station busted.

I was also a bit confused about the TT hand where an 800 stack raised to 400 and he just called. He said the guy with 400 behind would call if he pushed, so he might as well just wait until the flop. I don't see how that's going to get any hands that are ahead of him to fold ever, but sometimes a small PP can get away from him on the flop then. Is that desired?
