Learn How to Fork: Decisive Material Gain
This puzzle is a sharp opening tactic from the Grob Opening where king safety and loose pieces matter more than long-term structure. White’s queen invades the enemy camp and creates immediate pressure on multiple targets at once, turning a normal-looking middlegame into a forcing sequence. The key idea is that active piece placement can win material when the opponent’s king is still uncastled and several defenders are overloaded or undefended.
