Learn How to Exploit a Pin: Discovered Attack
This middlegame puzzle shows a classic pin-based tactical idea in the Ponziani Opening. Black’s kingside piece placement creates a vulnerable alignment, and White can use a forcing check to pull the king into a worse square while opening lines against the pinned defender. The key point is that the attack is not just about checking the king; it also exposes a loose piece that was overworked and unable to protect everything at once.
