Queens Pawn Game Chigorin Variation Clearance in Chess

In the Queens Pawn Game Chigorin Variation, “clearance” is the idea of removing a pawn or piece that blocks a line so a stronger move (often a rook, bishop, or queen invasion) can work. A defining feature is the early central tension where one side clears a file/diagonal by advancing or exchanging a pawn, creating immediate access to the opponent’s king or queenside targets.
