playing into someone's hands

Aiding your opponent

Playing into someone's hands means unwittingly doing exactly what benefits an opponent or adversary, helping them achieve their goals through your own actions.

The image comes from card games, where certain plays advantage the other player: By losing your temper in the meeting, you played right into his hands.

The phrase implies being manipulated or making a strategic error that serves someone else's interests.
