Dan Harrington was the player who caught my attention back when Moneymaker won, and his books have only solidified that opinion. He is clearly my favorite, though I also really like Jennifer Harman and Ted Forrest. I am also indebted to poker players who have written poker books that I find useful; that list includes: Doyle Brunson, TJ Cloutier, Daniel Negreanu, Phil Gordon and Barry Greenstein, whose charity work is also noted.
