Move the first pawn, say

OPEN

Think of the action that starts a game or conversation, often involving a first step or initial reveal. It’s the opposite of keeping things closed or secret.

Move the first pawn, say" hints at the start of a chess game, where the first move often involves advancing a pawn. The word "say" suggests this is an example, not a strict definition. "Open" fits because it means to begin something (like a game) and also sounds like the first move—opening play. The clue plays on both the literal action and the word’s double meaning.
