It has been said that chess is 99% tactics but whether that is an accurate reflection is hard to tell. Nevertheless, it is important.
But if you are like most players, you only discover the tactics after you come home and run through your game with a chess engine. So what to do? In the present book, you will be challenged 404 times but unlike most tactics puzzle books you don't know what your objective is: do I need to find a mate, find an opportunity skewer or pin a piece, use a tactical turn to gain a positional advantage and how far do I need to calculate?
These questions are you are faced with when you play your own games and therefore this book tries to replicate this position. Your one advantage over the players in the respective positions is that you know that there is supposed to be something in there for you to find.
Working through the puzzles and then carefully play through the thoroughly annotated solutions will help you to up your tactical radar as well as your calculation skills.
So if you are up for the challenge, here is the opportunity to take the leap forward. Good luck!
