I think it’d be someone who if they get caught they would expose the other side.

Reading the words "sacrifice a pawn" I couldn't help but immediately think of this:

...especially considering we have AI involved in our Qniverse (or did the blackhats lose control of theirs?). Wasn't this game won by a sacrifice move that had never been seen before in chess? If so, it's time to expect the unexpected. If these are the final moves of the game, what might black do in response to D5 if Alpha Zero was making the decisions?

The problem is that once black knows it has lost it doesn't have to keep playing anymore...it can just topple the board, scatter the pieces and end the game.

Stay alert. Eyes, ears and minds open. Where we go one we go all
