Calculate forcing lines.
Stop at a clear position.
Do not move pieces in your head randomly—build a candidate tree.
ConceptUnderstand before you move
Choose two or three serious candidates, calculate each with the opponent’s best defense, and compare the final positions using material, king safety, activity, and pawn structure.
- Start with forcing moves, but do not assume a check or sacrifice is correct.
- Visualize the board after each reply and track removed or relocated defenders.
- End the line only when the position is quiet enough to evaluate.
