kept one's cards close to one's chest

Hid one's intentions

To keep one's cards close to one's chest is to be secretive about one's intentions, plans, or resources—like a poker player concealing their hand from opponents.

The phrase implies strategic caution rather than deception: She kept her cards close to her chest during negotiations.

Also *close to the vest*.
