Learn How to Win Material: Discovered Attack
This middlegame puzzle is a classic example of a discovered attack that also creates a forcing check. One pawn move opens a line for the rook while simultaneously exposing the enemy king and queen to tactical pressure. The key idea is that a single tempo can do two jobs at once: check the king and uncover a major piece attack. In positions like this, material balance matters less than the hidden alignment of pieces and the vulnerability of the back rank and central files.
