Alekhine Defense Clearance in Chess

Alekhine defense clearance is a tactical motif in the Alekhine Defense where Black plays a move that “clears” a square, file, or diagonal so a piece can act with tempo. A defining feature is often the preparation of ...d5 or ...c5 breaks, or clearing the c- or d-file so the queen/rook can penetrate after the center is challenged. In practice, it’s about removing a blocker that currently limits Black’s most important attacking or defensive line.
