keep one's cards close to one's chest

Conceal your strategy

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

The phrase suggests strategic caution rather than deception: She's keeping her cards close to her chest about whether she'll run for reelection.

Also *keep one's cards close to the vest*.
