Turbo-Charge Your Tactics 1 is essentially a chess puzzle book, but not a typical one. It's a multi-year effort by Grandmaster Mykhaylo Oleksiyenko and his world-renowned trainer Vladimir Grabinsky to introduce you to the world of "unnatural" tactical moves. The engines might help to teach us, but they can also harm our understanding, so we must know when and how to use them.
Presenting examples of extreme beauty, no matter where they come from - be it online bullet or World Championship matches - this book will cure your "selective blindness" by destroying the false notion of chess principles being a set of rules, instead of helpful guidelines.
Most chess games are decided by tactics, so solving tactical puzzles is the smart path to improvement.
