Play the Dutch! - Part 1

GM Mateusz Bartel - 4-times Polish Champion:

In this book, a well-respected author provides you with a solid foundation for including the Dutch in your repertoire, dealing with almost all the sidelines you could possibly meet after 1. d4 f5. I have been playing this opening for more than 20 years now and I am positively surprised by the amount of useful material inside. Studying it (and later the second part with the main lines) can help you to acquire a lifetime weapon, which is especially efficient against solid players."
