2. The "Endgame Conversion" PGN

Calculation is often associated with flashy middlegame tactics, but GMs know that the hardest calculation occurs in endgame transitions.

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.

Train your "combinational vision" to find those quiet, surprising checks or captures tucked inside a long sequence. Building Your Training PGN Drills: Find all legal captures and checks first

Training methods & tools

• Blindfold visualization: move pieces in your head for 6–8 ply.
• Chunking: recognize pattern templates (mate motifs, typical sacrifices).
• Tree pruning: evaluate move types (forcing first), discard unlikely branches.
• Reverse thinking: assume opponent’s best response, then build.
• Tablebases/endgame databases for checking exactness.
• Use engine sparingly: first calculate fully, then verify.
