Cia, have you ever heard of the Harrington on Hold'em series?.
If you can, at least check out the first volume. Many people have said that it's geared towards a more advanced player, but I have to admit that I found most of the information in it fairly straight forward and very easy to understand. I know you play in your share of tournaments and that's what the series is about. No-limit Hold'em tournaments. I'm sure you won't find it too challenging, and even so, the more we challenge ourselves, the more we learn, right?.
Let me know what you think.
