Rat Defense Antal Defense Interference in Chess

Rat Defense Antal Defense Interference is a tactical motif where one side disrupts the opponent’s defensive piece line by forcing an “interference” between the defender and its target. In the Rat Defense Antal Defense family, the defining feature is that a key defender (often guarding a critical square or file) is made to block or lose its connection after a forcing move. The result is that the defense that looked solid becomes temporarily ineffective, allowing a win of tempo, material, or a decisive attack.
