“Yusupov series of books (Build up your chess, Boost your chess, Chess Evolution) for players in 1000-2200 level approx. is good recommendation.”
GM Ramesh, probably the best trainer in the world. Trainer of Praggnanandhaa, Aravind and many other promising young Indians.
“Each chapter starts with the introduction of a theme followed by progressively more difficult examples and finally exercises to solve with detailed solutions. Such an approach has been seen before but never as well done. One might ask why it is necessary to have such a high rated player write a book for less-advanced players? The answer is that Yusupov offers the rare combination of tremendous chess knowledge and the ability and desire to share it. This book will be useful to not only budding Masters to be, but especially those who coach them… Highly Recommended”

“I would like to once again draw attention to the perfect chess lessons by Artur Yusupov, published in no less than nine beautiful parts by Quality Chess.”
