Learn How to Clear the File: Classical Chess Mate in 2
This classical chess puzzle comes from the French Defense and shows a sharp middlegame tactical refutation. White’s pieces are active, the black king is stuck in the center, and the open file near the king becomes the key battlefield. The idea is to use a forcing check that clears the way for a rook invasion, turning activity and king safety into a direct mating net. It is a great example of how a small tactical detail can decide a position immediately.
