Sicilian Defense Closed Puzzle (Rated 912): Skewer — Win Material

This Sicilian Defense Closed position showcases a powerful skewer against a materially stronger opponent. Black has the bishop pair and an extra bishop, but the pieces are tied together along the open d-file. White’s active bishop and rooks create a tactical alignment that overloads the defender and exposes the back rank. The key idea is to use forcing checks to attack the pinned line, compel a recapture, and then invade with the remaining rook for a decisive advantage.
