Learn How to Win Material: Crushing Fork
This puzzle comes from the Bishop's Opening and shows a classic tactical refutation in the middlegame. Black’s active rook invades with check, and the key idea is that White’s queen and knight are overloaded by the king’s safety and piece coordination. The position is not about a mating attack; it is about forcing exchanges that leave White down material. In practical terms, this is a crushing fork-style tactic that wins the queen and simplifies into a clearly better ending.
