Aggressive Openings For Black Puzzle (Rated 868): Pin — Sicilian
This Sicilian Defense middlegame puzzle demonstrates how a pinned piece can become a tactical liability. White’s extra material and active bishop create the impression that Black is under pressure, but the position contains a forcing sequence based on a skewer and a discovered attack. The key idea is to exploit the connection between the exposed bishop and the knight shielding the king. Once that defender is removed, White suffers a decisive material loss.
