Learn How to Win Material: Discovered Attack
This middlegame puzzle centers on a classic discovered attack: one move opens a line for a bishop while also creating a direct tactical threat. The position is balanced materially, but White has the more active setup and the better central prospects. The key idea is to use a pawn advance to reveal pressure on a vulnerable target, forcing Black into a response that leaves another weakness exposed. It is a clean example of how activity can outweigh static equality.
