Howard Lederer is often called "The Professor" of poker, not just for his encyclopedic knowledge of the game, but also for his willingness to share that knowledge with anyone who is willing to listen.

His website, Howard Lederer dot Com contains a wealth of information, from commentary on other pros, to the underlying philosophy of the game.

And it's and understanding of the philosophy of the game that's made all the difference for me as a player. I've found that all the starting hand charts in the world are useless without an understanding of the underlying philosophy of the game. know that I shouldn't play KQo from the SB in a re-raised pot . . . but why? I know that it's a good idea to get all the money in pre-flop with AKs on or near the bubble in a SNG . . . but why? I know that, late in a tournament when I have to make a move it's better to jam with A3o from UTG than it is to call with A5s from LP . . . but why? And how do I stay focused for hours at a time, when there is a possible life-changing money at the end of the final table?

In the article I've linked today, Howard goes right into the why of tournament poker, from a Zen perspective, which includes advice that's quite useful away from the tables, too.
