Deception. Moving a piece on a game board should have more than one effect. One should preferably make it so that the most obvious effect (exile) is not the one that's actually the most valuable in the long term (taking root in adverse country). Bonus "inception" points if you can make the adversary believe that you did it because they forced you to (sanctions).
