Modern chess theory often considers time and development to be more important than material. Sacrificing pawns has been standard opening practice for centuries but ten or fifteen years ago leading theoreticians developed more and more opening lines in which one side regularly gives up the exchange. Such sacrifices in the opening lead to strategically and tactically complex positions and give the well-prepared player good winning chances. On this 60 Minutes renowned and successful coach Adrian Mikhalchishin shows you openings with early exchange sacrifices. These openings enrich your repertoire, improve your chess, and give you an opportunity to witness the development of modern chess theory.
