Blackmar Diemer Gambit Netherlands Variation Clearance in Chess

In the Blackmar-Diemer Gambit (Netherlands Variation), “clearance” is a tactical motif where White removes a piece or square’s blocking power to open a line—most often for the queen, bishop, or rook—so a follow-up threat lands with tempo. A defining feature is the early pawn structure and piece placement that makes a specific square (commonly on the d- or e-file) crucial for the clearance to work.
