How to calculate (step-by-step)

1. List candidate moves (prioritize checks, captures, threats).
2. Identify forcing lines (checks/captures/promotions) and calculate them first.
3. Visualize resulting positions after each reply; note piece placement and pawn structure.
4. Evaluate terminal nodes (material, king safety, passed pawns, activity).
5. Prune branches that are clearly inferior or equal.
6. Re-check critical lines for hidden tactics and quiet moves.
7. Decide and simplify—if multiple lines equal, choose the practical one.
