“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.
“As mentioned in previous reviews of this series, these books have three principle audiences. They will be useful for players wishing to increase their strength to improve their rating, for coaches looking for a structured curriculum and/or useful training material and for those who wish to increase their understanding of the game that, because of various circumstances, may no longer be able to play regularly. While Yusupov modestly cautions in his introduction that this series is not a substitute for a trainer, there can be no question that the motivated student working alone can glean much knowledge.”
IM John Donaldson (full review)
“These books are all an improving player needs to achieve great results! Every serious player and legitimate chess coach should have the entire series. It is a far better investment than any opening book.”

“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.”
