The Chess Bible

I believe the answer lies in the following:

1. Smart research before picking up a source to study from.
2. Learning from someone who has walked the talk, who has achieved what you
   want to, or has students who have done that.
3. Forget about the word “useful”. You won’t be able to read and watch all the
   useful books and courses. Instead, change it to “the most effective.”

What’s the most effective book for your level or the most effective course to get? As a Grandmaster and chess coach, who left his cozy life and started a company with a mission to help chess lovers unlock their full potential, I’m very happy that in the chess world there are people like Vishnu and that you picked his book.

Vishnu isn’t an ordinary person; his methods of improvement aren’t ordinary, and neither is he as a coach. When he won the Chicago Open, despite being 60th out of 116 in the starting list, many people were surprised. But they wouldn’t be if they Saw how smart and interesting his system of chess improvement is. Vishnu proved
that his methods work and how important pattern recognition is. And exactly that's
what he teaches in this book!

When I saw the draft of it I was blown away by the hard work he had done, the quality of the research, and how carefully he was choosing the examples. I want to congratulate you on having this book in your hands. You avoided traps, you found a man who has walked the talk and has spent years learning and preparing for you material that you can digest in a short period of time. And if your rating is somewhere between 1000-2000, this book will be one of the best books for you!
