Removing the Defender: Undermining the Defense
Removing the Defender (also called Elimination of the Guard or Undermining) is a tactic used to destroy the opponent's coordination. When a piece performs a vital defensive task—like guarding a piece, a mate threat, or a key square—you remove it (usually by capture) to leave the target defenseless.
