PSI Hands, Thoughts?

[theBruiser500]

I think there were a couple of interesting hands in the PSI touranment. First there was Doyle Brunson raising to 12k, blinds of 1.5/3, antes of 300 with A2s, then Howard Lederer moves in for 80k I believe with AJo. I guess his stack size is such that if he raises he is pot comitted but why raise in the first place then? He risks so much to win such a small pot in situaiton where if he is called he will probably be slightly behind or behind by a lot. Also, he has people to act behind him... I don't get that play by him.

Then there was the hand with Brunson having A4o he limps in SB and Gus checks with T7, flop is AKx, Brunson checks, Gus checks. Turn is T, Brunson bets 10k and Hansen raises to 20k. What was Gus thinking when he did that? For metagame reasons, and to get a cheap showdown, and to disguise his hand if he hits?
