Learn How to Mate in 2: Fork Tactic
This middlegame puzzle is a classic tactical refutation built around a forcing fork and a mating net. White’s active knight creates a direct check that also overloads Black’s king position, while the queen is ready to exploit the weakened back rank and exposed king zone. The key idea is that the first forcing move limits the king’s escape squares and leaves Black with only one reply, after which the final attack lands immediately. It’s a strong example of how piece coordination can convert initiative into checkmate.
