Attraction (Decoy): chess tactic

Bring a piece onto the square you need.

Attraction encourages or forces an enemy piece onto a square where your next move works. That follow-up might be a fork, skewer or mating attack. Explain both the offer and the attack it enables.

• Name the square you want the piece to occupy.
• Calculate the follow-up before offering material.
• Check whether the opponent can refuse the offer.
