What is the best way to calculate a tactical chess puzzle?

White’s rook activity on the open file creates a tactical refutation that wins material and transforms the evaluation. The key idea is to compare immediate captures with slower positional moves, especially when the opponent’s last move creates several hanging or inadequately protected pieces.
