A classic, to be sure!
I went through this as a beginner, and learned quite a lot. Probably useful up to about 1700. Hopefully it's been translated to modern notation by now, so make sure you check on that. The language is a little stodgey, but you'll get used to it. :)
"My System" Anyone waded through this book by Nimzowitsch? What level player is it good for? Reviews?
Thx
