Your favorite chess book

[Crossroad]

My favorites are probably My 60 Memorable Games by Fischer and the huge huge puzzle books by the father of Polger sisters. What are yours?

Nimzowitsch "My System"
Great Book!

[Crossroad]

It's a great book and it was one of my first chess books I read. Though, I agree with GM Thomas Luther who once said, that this old book are nice to read, but when it comes to chess those old books are the the first choice because some concepts are just wrong or has been improved over the years. He compared it to physic or math books: The old books from Galileo or Newston are great and worth reading, but when it comes to physics (and not history of physics) it's better to read new books.

So, I would recomment to read "My System", but then continue to read "Secrets of Modern Chess Strategy: Advances since Nimzowitsch" by John L. Watson to get a better picture of what is wrong and what is right.
