play someone false

Deceive a trusting person

To play someone false is to betray or deceive them, especially by acting contrary to promises or professed loyalty.

The phrase is literary and somewhat old-fashioned: His memory played him false, She played him false and married another.

When memory or senses play someone false, they mislead rather than betray.
