संक्षेप में

Black’s knight just jumped from f6 to d5. Every move does two things: it goes somewhere, and it stops doing what it did before. What was the knight guarding on f6?

यहाँ आप क्या सीखेंगे

• After every move, ask what it attacks and what it stopped guarding.
• A defender that moves away often leaves a tactic behind.
