Alekhine Defense Two Pawns Attack Clearance in Chess

In the Alekhine Defense Two Pawns Attack, Black often uses a “clearance” idea to remove a pawn that blocks a key line (typically for the queen, bishop, or rook). The defining feature is that White’s advanced pawns create space, while Black needs to open a file/diagonal at the right moment to activate pieces and hit the center. This motif is about sacrificing or shifting a pawn to clear the path for an immediate tactical follow-up.
