Learn How to Win Material: Discovered Attack
This middlegame position is a classic tactical refutation built around a discovered attack and a hanging piece. White has a strong tactical idea because moving the e-pawn opens the e-file, immediately exposing the black bishop on e5 to the rook. At the same time, Black’s knight on c3 is loose and can be targeted by a lower-value piece, so the position is full of forcing moves. The key lesson is that active pieces and undefended pieces often outweigh static material deficits.
