Comparison method

The comparison method is used when several candidate moves, options worthy of serious analysis, remain viable. Instead of demanding an exact, isolated verdict for every continuation, the player asks which resulting position is preferable to the others.

For a fair comparison, each candidate should face a strong reply and be calculated to a reasonably stable point, where no immediate check, capture, or threat is about to change everything. The player then compares understandable factors: material, meaning pieces and pawns; king safety; activity, or how freely and usefully the pieces can act; pawn weaknesses, meaning pawns that are difficult to defend; space, the board area each side safely controls; risk; and practical difficulty.

The conclusion can be relative. There is no need to assign an exact number to every position. It may be enough to determine that one option keeps equality, another creates an unpleasant defense, and a third produces a clear advantage. That ranking supports a decision even when none of the positions is completely simple.

The method often follows the candidate-move method. The elimination method first removes options that fail concretely; comparison then separates the remaining choices.
