Calculation Step by Step: A Grandmaster’s Training Guide Vol. 1 - Foundations
by Surya Ganguly
If one skill decides more games, it’s calculation. Openings fade, plans change - but seeing clearly, comparing lines, and choosing with confidence wins points. In this course GM Ganguly turns calculation into a trainable skill with a structured path for any level. You won’t just solve tactics; you’ll learn how to think: where to start, which branches to explore, when to stop, and how to keep a crystal-clear mental board under pressure.
What’s different: idea-first training (by thinking tools, not random puzzles); tournament mindset (treat every task like a real game); scalable practice (10 minutes or a full session); practical methods (visualization, blind training, decision routines); honest coaching (no miracles - just habits that raise your ceiling).
Volume 1 - Foundations: define forcing moves properly; master short calculation (where most blunders happen); train visualization; use elimination (incl. Ganguly’s “floating moves”); compare final positions and link patterns. Guided work with pause points, model examples, and actionable takeaways.
