I decided to write about something that I would be interested to learn myself. In this book: • I show what preparation for a game by a 2650 player looks like. In chess, we only see the game on the stage, and can only guess at what is hidden behind the scenes. Top players can't reveal this, nor can their seconds, so I decided – who, if not me? • I show my preparation for games, accompanied by analyses that I consider enough to apply the opening line. • I show how I outplay opponents, not with powerful opening preparation, but by leading them into positions that are pleasant for me or unpleasant for them. • I explain things that many players do not pay attention to in terms of opening preparation and preparation for an opponent.
