IMO, overall..... he tends to suggest play that is a bit riskier than I like when it comes to making big calls based entirely on pot odds. It's like I value that whole "once you are out of chips, your tourney is over" thing than he does.

Hell, maybe we'll have some contests and give away some free copies around here
