This is the best book on N-C6 that I am aware of. I started playing these lines as a kid because in my area this opening was popular. Meyers is a well known N C6 expert and I played against him and going over our game he convinced me that this may not be the best opening but it is hard to play against if you are not prepared. I have a lot of material on this opening and if you play these kind of lines then you must have this book. I like how it was organized and it is easy to read. It helped to bring my other material into focus. Meyers has his own book on N-C6 but this one is 10 times better.
