This is the second book of the Thinkers’ Chess Academy series. In the first book we started at a beginner’s level with checkmates in 1, 2 or 3 moves and the most common tactical motifs. If you have already worked with the first book you will now be much more experienced and ready for some more difficult lessons. We will start with 50 combinations to refresh our memory of the motifs from the first book. Th e chess friends who have not read the first book can treat it as a kind of self-test. If you cannot solve many of the examples it may be better to go back and work through the first book again. It is not a good idea to leave basic knowledge out. It will certainly hinder your progress if you do so. In this book we will not only show you more tactical motifs, but we will also give you an introduction to the basics of chess strategy. You will learn the most important elements of strategy which will help you to find better plans and to understand positions better. At the end of the book a chapter with 50 checkmates of 5+ moves will show you techniques of how to attack or hunt the opponent’s king and also how to improve your calculation skills and your imagination at the chessboard. Now enough of the prologue, let us go to work and learn lots about chess tactics and strategy! Have a lot of fun while studying chess and enjoy your improvement! Yours, Thomas Luther Grandmaster and FIDE senior trainer
