"Best of all, Zuke 'Em (roll over to see Amazon Ratings) is fun to read. The author does not assume you are a world-class player. Instead of reading like a chess book, it reads like he's just sitting with you at the bar showing you chess moves over onion rings.
David Rudel has played the Colle-Zukertort, and nothing but the Colle-Zukertort, for over 10 years, and he spent a great deal of time ironing out the wrinkles of this opening. "

i think it goes to prove my theory on books "more interesting cover= the worse the book" 😉
