Polish Opening Bugayev Advance Variation Puzzle (Rated 1359): Win Material — Discovered Attack
This puzzle shows a classic opening tactic where pressure on the queen and king side creates a forcing sequence. Black’s active bishop move is not just a check; it also opens lines for the queen and exploits the exposed white king in the center. The key idea is a discovered attack: one piece steps with tempo, revealing a stronger threat behind it. In practical classical chess, these forcing moves often win material by making the opponent’s queen or bishop impossible to save.
