Learn How to Spot a Fork: Colle System Tactic

This puzzle comes from a Queen’s Pawn Game Colle System structure where the position looks stable, but tactical pressure has already built up around the white king and queen. Black’s active knight jump creates a forcing sequence that combines check, fork, and piece activity. The key lesson is that in the middlegame, a seemingly modest tactical shot can override material balance when the king is exposed and the queen is overloaded. Always ask which checks and forks become available after a forcing move.
