Mark Dvoretsky, renowned as the world's leading chess trainer, has significantly influenced the chess world through his innovative training methods. His students, including Artur Yusupov, Nana Aleksandria, Sergey Dolmatov, and Aleksey Dreev, have achieved remarkable success, winning youth World and European championships and later earning Grandmaster titles. Many of these players even competed in candidates' matches for the world championship, showcasing the effectiveness of Dvoretsky's training approach.

A key component of Dvoretsky's success was his unique exercise cardfile, which was once exclusively available to his select pupils. This cardfile contains a wealth of highly instructive positional exercises and tasks designed to enhance the practical skills of chess players. These exercises focus on developing essential skills such as positional understanding, imagination, calculation techniques, setting traps, and making favorable exchanges at critical moments. After extensive efforts in computerizing, classifying, and verifying the material, this valuable resource is now accessible to all aspiring chess players, particularly those at advanced levels, ranging from experts to grandmasters.

The newly computerized system allows players to utilize modern training methods that were previously unavailable or limited to direct training sessions. This system offers a comprehensive course that includes 200 carefully selected exercises tailored for expert, master, and advanced players with an ELO rating between 2000 and 2400. The exercises cover crucial chess themes such as strategy and planning, calculation of variations, endgame technique, and defending inferior positions.

This course is part of the Chess King Learn series (https://learn.chessking.com/), a groundbreaking chess teaching method that spans various aspects of the game, including tactics, strategy, openings, middlegame, and endgame, catering to players from beginners to professionals.
