"Do you use chess to simulate warfare?"

"Hahaha, chess is just for fun and games. It's all about starting off on equal footing, having gains and losses along the way, and reaching a decisive result at the end.
"Well, the same doesn't apply to warfare. Every soldier in my army is human. Their emotions and morale are way harder to anticipate than some lifeless pawns on a predetermined chessboard.
"What we want to achieve in war is not fairness but to create as many disadvantages as possible for our enemies.
"Circumstantial victories should not lead to complacency. If unable to win, one should retreat early to preserve strength. That should also qualify as a type of victory, wouldn't you say?"
