Learn How to Win Material: Tactical Refutation
This puzzle comes from the Slav Defense and shows a classic middlegame tactical refutation. White has active pieces and a strong-looking knight outpost, but the position is tactically unstable because one piece is overloaded and another is vulnerable to a forcing sequence. The key idea is to use forcing moves to win material while keeping the enemy king under pressure. In classical chess, these long opening tactics often decide the game before the endgame ever begins.
