Learn How to Win Material: Crushing Fork
This puzzle comes from the Reti Opening and shows a classic tactical refutation in the opening. White has just placed a bishop aggressively on a3, but that piece is overextended and can be punished immediately. The key idea is that a forcing capture can open the door to a check and a follow-up win of material. In practical classical chess, these motifs often appear when development is incomplete and one side’s king is still vulnerable to tempo-gaining threats.
