Learn How to Win a Fork: Decisive Material Gain
This puzzle is a classic example of a tactical refutation in the Queen's Gambit Declined Exchange Variation. White’s knight jumps into a powerful outpost with tempo, creating a fork that hits multiple high-value targets at once. The key idea is that a forcing move can outweigh static material deficits when the opponent’s queen and rook are poorly coordinated. In practical classical chess, these short combinations often decide the game immediately.
