The real wisdom here isn't about dirty fighting—it's about identifying your opponent's foundation rather than engaging them where they're strongest. When a boxer obsesses over a champion's quick hands, he loses; when he attacks the base that makes those hands possible, the entire structure collapses. In business, this might mean a startup doesn't try to outspend an established competitor's marketing budget but instead targets the supply-chain assumptions that competitor relies upon. It's a reminder that victory often belongs not to the direct challenger, but to whoever thinks structurally about where power actually originates.
