The map of your weak spots

What is your rating?

It weights the diagnosis: what costs you points changes with strength.

Most chess books teach the game. These fix the way you lose it.

A general manual gives your weakness a paragraph and your strength a chapter. Here it is the other way round: one book, one leak, until it closes.

  • 01

    One problem per book

    No pages about mistakes you do not make.

  • 02

    Named, not vague

    If the title does not describe you, do not buy it.

  • 03

    Built for your level

    Beginner, intermediate or expert, marked on every cover.

Six grandmasters. 14 years spent making other people better.

In 2011 six grandmasters founded a club to bring chess to their country. Since then they have brought on hundreds of players.

A strong master knows how to play. Someone who has taught for 14 years knows where you get stuck.

The things people ask first

Who actually writes these books?

A working group of 6 grandmasters. Each writes only in the area they compete in, and a second titled player reviews it.

What if the book is not what I expected?

You have 14 days for a full refund, no reason needed. Write to the address on your receipt.

How quickly will I see a difference in my games?

It shows first in the games where that mistake used to appear, usually within a few weeks.

Are these for beginners or strong players?

Both, but not the same books: every title carries its level on the cover.

Why not just use free videos and puzzle apps?

Free material is organised around what is easy to publish. These books start from where you lose.

What do I actually receive, and what can I read it on?

A download that arrives with the payment, readable on any device of yours, Kindle included.

Which three would change your results?

Three books at US$39, downloadable within a minute.
