Cardplayer, my apologies, I'm traveling on business and don't have my copy of the book with me...
so I'm going to respond directly to what you've posted here, rather than what pearljammer actually wrote...
Suggestion - may be better to do this like HA, and not post the whole hand, since the results tend to color the discussion.
In general, I was surprised by pearljammer's approach to early tourney play - it's pretty tight/weak in the early rounds.
1. My natural inclination would be to 3bet TT from SB to about 150 rather than flat call. If I remember right, he's explicitly setmining here, and the fact that seat 6 flat called played into that decision. If we hit the set, we stand to gain chips against seat 3 if not seat 6, and it's a cheap flop (relative to stack size) to see. No need to go crazy at the first level, when everyone will call light and hit on seemingly dry boards - and the potential reward doesn't outweigh the risks of playing aggressively on the first level.
On the other hand, I like TT a lot, so I still think I'd 3bet even at the first level.
2. Seat 3's minbet, in the first level, indicates either a fishy player or a monster. Another reason I'd rather 3bet from SB - I'm pretty sure I'm ahead of both seat 3 and seat 6 preflop, and the 3bet would clarify their hands (I'm folding to a 4bet, playing cautiously if seat 6 calls).
3. We have an overpair to the board on the flop, seat 6 didn't show any particular strength pf, and I'm still thinking seat 3 is a little fishy. If we'd 3bet pf, we're leading the flop - since we called pf, checking makes sense.
Now, with the read that seat 6 is a solid player, the fact that he calls seat 3's potsized bet is a concern. That puts him on an overpair or a set, much less likely two pair or a draw (86s? maybe?). Calling a pot sized bet in a multiway pot with (probably) top pair, where the player IP is a good player, makes this a pretty easy fold since we're not really invested in this pot.
So part of pearljammer's specific style, I think, is to only aggressively attack early pots if you're clearly ahead - save the more aggressive play for later rounds (ante rounds). Definitely something for me to think about, since I tend to be aggressive with 88+,AK in early levels.
I hope others respond here, this is a great idea Cardplayer - obviously I'm interested in your thoughts here as well.
