Removing the defender — what it means in chess
Capturing or chasing away the piece that guards a key point.
Capturing or chasing away the piece that guards a key point.
Removing the defender is the bluntest of the guard-fighting tactics: the piece holding your target together is captured outright, and the price — often a full exchange — is paid because what falls afterward is worth more. No lure, no chase, no geometry. The guard dies, and the tactic that was impossible becomes forced.

The queen-and-bishop battery aims at h7, but the f6 knight guards it alongside the king — two defenders against two attackers, and the tactic fails. Rxf6 — the rook captures the guard outright. An exchange is offered for a knight, and the arithmetic on h7 changes forever. gxf6 — Black recaptures. Taking with the queen instead changes nothing on h7: the pawn shelter is what mattered, and the guard is gone either way. Qxh7 — the battery fires. The bishop behind the queen forbids the recapture, and Black's own bishop seals f8."]]
Compare the trio directly: deflection chases the guard, overloading out-tasks it, and removal deletes it. The most forcing option usually costs the most material — which is why counting what falls afterward is the whole calculation.
