Learn How to Win Material: Discovered Attack
This middlegame puzzle comes from the Russian Game and shows how a discovered attack can turn king safety into a decisive material gain. White’s pieces are active, but Black can exploit the exposed king-side structure and the loose queen-side coordination. The key idea is that forcing lines around the king can create a tactical refutation where a capture with check opens the way for a follow-up win of the queen. In practical classical chess, these patterns often decide games quickly.
