Way off topic, but there's a very old. little known (almost a secret) classic chess book by Aron Nimzowitsch called 'My System' which is simply fantastic. Kind of like a pool lesson with Scott Lee that just transforms the way you play. HIGHLY recommended, if your kids have the motivation to absorb this kind of stuff they'll be way ahead of the pack in their chess conquests. I pretty much owe my meager successes in chess to this book.
Totally on topic! I'm getting this book!
