French Defense Rubinstein Variation Sacrifice Intermediate Puzzle (Rated 1482): Spot a Mate in 3 — Kingside Attack

This middlegame puzzle is a classic example of a forcing kingside attack where the defender’s king is exposed and tactical motifs work together. White uses a bishop sacrifice to drag the king into a vulnerable square, then follows with a discovered attack and a mating net. The key idea is not material gain, but forcing the enemy king into a position where every reply is limited. In classical chess, these patterns often appear when the opponent’s king shelter is weakened and the attacking pieces are already aimed at the king zone.
