What is the best way to calculate a chess puzzle?

Begin with checks, captures, and forcing threats. After finding candidate moves, list the opponent’s legal responses and calculate the resulting positions before choosing the move that gains material or creates a lasting advantage.

Strong tactical play often begins by identifying overloaded or immobilized pieces before calculating checks, captures, and direct attacks.
