NZCF Online Chess School: Calculation Fundamentals – From Ideas to Moves – Ishan Wiratunga

NOTE: THIS IS A CHESS COURSE, NOT A TOURNAMENT

Calculation Fundamentals – From Ideas to Moves (Feb/Mar 2026) 

Strategy tells you what you want to do; calculation tells you whether you can do it.
Good calculation turns ideas into results.. It reduces blunders, improves decision-making in critical positions, strengthens both attack and defence, and allows players to convert advantages with confidence. Strong calculation replaces hope with certainty and is essential for accurate tactics, endgames, and overall improvement.
