In the second volume of his video course 'Calculation Step by Step', Grandmaster Surya Ganguly presents advanced chess techniques aimed at improving players' calculation abilities. The course is divided into three thematic chapters: Attack & Defence, Long Calculation, and Imagination & Unusual Moves. Each chapter contains exercises that challenge players to think outside the box, emphasizing the importance of creativity in chess. Ganguly highlights the need for players to discard conventional wisdom, as illustrated in a game between Nigel Short and John Miles from 1984, where an unconventional move could lead to a decisive advantage. The course also features insights from Grandmaster David Navara, who provides practical advice on when to deeply calculate positions. Overall, this course is tailored for ambitious tournament players, focusing on understanding concepts rather than rote memorization, with the goal of enhancing the calculation process in chess.
