Robatsch Defense Puzzle (Rated 814): Win with a Fork — Decisive Material Gain
This puzzle is a classic middlegame tactical shot where a knight jump creates a crushing fork against the king and major pieces. The key idea is that forcing moves can overload the defender and expose a trapped heavy piece. White’s active knight and queen coordination make Black’s king safety the dominant weakness, so the tactic works by combining check, tempo, and material gain rather than slow maneuvering. It is a strong example of how piece activity can outweigh equal material.
