Preface After writing my exercise book “The Chess Manual of Avoidable Mistakes – Volume 2”, I wanted to continue in the same spirit by launching another series of books: “Chess Calculation Training”. This first volume will focus on middlegames. I have always found that existing puzzle books, however good they are, only provide a rather mechanical form of mental training. In this new collection, you will find exercises to help you improve in specific areas of thinking, such as you may encounter in your own games. To help this, all the problems are taken from real games, with most of them having taken place in the last year. The book begins with a warm-up. After that, you will find several types of exercises. Some of these fall into the same categories as those in my previous book, as they were readers’ favourites. Other categories are completely new, for instance: “Find the killer positional move!” or “Find the stunning winning move!”. The problems in the book are accessible to players with a level from modest to confident. The most difficult ones are marked with an asterisk, while the most challenging chapter comes with a help page, that you may check when necessary. I hope you enjoy solving these 496 puzzles, and look forward to seeing you again in Volume 2: Endgames. Romain Edouard 01.03.2017

Chapter 1 Warm up As the title indicates, this part of the book is a warm up. For each position given, you must find the winning move. If there seem to be more than one, you should go for the quickest and/or the clearest. This chapter contains exercises of all types, which could have been used in several of the other chapters. They have been collected in this chapter because of their lower difficulty and will prepare you nicely for the rest of the book! This chapter is quite long: I recommend attempting one or two pages (4 to 8 exercises) as a daily routine, or as a warmup before looking at another chapter.

Chapter 2 Punish bad coordination! In this chapter, the move or idea which you must find is linked to a lack of coordination in your opponent's pieces. Keep in mind these issues which you may be able to use to your advantage: trapped pieces, a lack of free squares, undefended or badly positioned pieces, delayed development, a fragile setup. The difficulty of these exercises ranges from quite easy to moderately difficult, unless an asterisk indicates that the exercise is more difficult.

Chapter 5 A devastating attacking move! In this chapter, you are on the attack. In each exercise, you must find an incisive move to destroy your opponent's defence: a sacrifice, a combination, a stunning attacking move or any other ambitious move which is devastating to the opponent's King. One important piece of advice: do not necessarily look for artificial solutions, sometimes the move may be simple. This chapter will help you to develop your sense of initiative and to improve your calculation skills. The difficulty of these exercises ranges from medium to difficult. An asterisk indicates that the exercise is more difficult than average.

Chapter 6 Find the stunning winning move! This chapter contains a selection of difficult positions where you must find a spectacular or unusual winning move. In most of the exercises, the "hidden" winning move is made immediately. In a few examples, however, it is on move 2, the first move being merely preparatory. You must focus on the following issues: seriously disrupting your opponent’s coordination, preventing problems (prophylaxis: finding your opponent’s ideal move should lead you to the solution!), bringing an extra piece into the action, destroying the enemy king. You may wish to use the help page which you will find at the end of the chapter. Don’t give up!

Chapter 8 Find the missed move! In this chapter, each position is accompanied by a series of moves which were played in a game. You must find the missed opportunity in this series of moves. The player whose move it is in the given position is the one who missed an opportunity. In order to help you in your search, I will also give you the evaluation of the position if that missed move had been played. The aim of this part of the book is to encourage you to concentrate on what is important, looking at the whole board, so you can spot key moments. These exercises will also help you to find the right balance in your analysis: passing quickly over obvious things while making sure to notice possible surprises, so you develop a feeling for when the key moment has arrived. The difficulty of these exercises ranges from medium to difficult, unless an asterisk indicates that the exercise is very difficult.

Chapter 9 Evaluate the opportunity! For each exercise in this chapter, I will suggest a possible move. You must say whether the move is good or bad and evaluate the resulting position in the same way as a chess engine: White is winning, Black is winning, White is better, Black is better, or the position is equal or unclear. You must find the key continuation and explain why the suggested move does or does not work. This is intended to replicate a game situation, when you must analyse a critical candidate move. The difficulty of these exercises ranges from medium to difficult, unless an asterisk indicates that the exercise is very difficult.

Chapter 10 Make the right choice! In each exercise in this chapter, I will suggest two possible moves. One of them is a blunder! You must decide which is right and, most importantly, the reason why the other one is a mistake. Generally, if the two moves suggested are quite similar, you must find the key continuation in both lines, in order to discover a final important nuance. If the two moves are very different, you must find a clear refutation of one of them. This chapter is intended to help you to work on your calculation skills, while developing your sense of danger when you need to rule out a move which seemed good at first glance. The difficulty of these exercises ranges from medium to difficult, the most challenging ones being marked with an asterisk.
