Discovered Attack Puzzle (Rated 1316): Win With a Discovered Attack — Pin Tactic

This middlegame puzzle is a classic example of a tactical attack built around a pin and a discovered attack. The key idea is that one piece can move with tempo, exposing a stronger line of attack on the enemy king and queen. When the king’s shelter is weakened, even a material lead can disappear quickly. In practical classical chess, these positions reward alertness to forcing moves, especially checks that also create direct threats.
