A defender can serve several roles. Removing or distracting it matters only when the follow-up works against the opponent’s best response.
What to do
Identify the target and its defenders, then calculate captures, exchanges or forcing moves that change the protection. Recount attackers and defenders in the resulting position.
A mistake to avoid
Do not assume an exchange removes the only defender. A recapturing piece may take over the same defensive role.
A detail worth checking
Recount after the full exchange sequence. Tactical exercises often depend on what remains at the end, not the first defender disappearing from its original square.
Try this practical check
Use a verified tactical exercise and draw the defensive connections before solving. Remove one connection mentally, then check whether another still protects the target.
