Small Stakes No-Limit Hold’em

Definitely. If you're always "looking for knowledge", and you've gotten a lot out of resources like Ed's vids, I think you'll dig this book a ton. I have students who are strong 1-2 full ring players, and they always get a lot out of discussing many of the very topics that are in this book – stealing, barrelling, hand reading, etc. Heck even 5-10 6-max players will probably get something. Obviously the more advanced you are, the less some of the general ideas will be new to you, but who doesn't like a refresher? Plus, for people that are already doing well at those stakes online, a hundred bucks is a trivial amount. Even if the book helps them just a little bit, it's hard to imagine it not being worth the investment.
