Learn How to Double Check: Mate in 2
This chess puzzle is a classic forcing sequence built around a double check, one of the most powerful tactical motifs in classical chess. When a king is exposed and the attacking pieces coordinate, a checking move can create immediate threats that cannot be met by a capture or block in the usual way. In this position, the attack is especially dangerous because the black king’s shelter is already weakened and the white queen is active near the king zone.
