Choosing the subject wasn't easy at all, since the topic of defense requires a comprehensive analysis from different angles in order to give the chess player under pressure useful guidelines during a game. Of course, the technical part is a matter of finding challenging, new and interesting positions. I was struggling with describing the emotions that we have during the game, how they influence our decision-making process and what we can do about that. Hence, I tried the best I could to define the issues the defender encounters during a stressful game. Finally I am confidently sharing with you the lessons that I learned from sport psychologists and literature, and my experience as a player over 30 years. GM Jan Werle November 2021
