White’s active queen and rook coordination create a discovered attack against the black king and loose back-rank pieces, turning a static material deficit into a winning combination. The key is that the checking move is not just a check: it also clears the line for another piece to win material. In classical chess, these tactical shots often decide the game immediately.
