Zero-Sum Game

Activate when: someone asks 'are we fighting over a fixed pie?', 'should we cooperate or compete?', 'is the market growing or are we just stealing share?', uses phrases like 'winner-take-all', 'race to the bottom', or 'your gain is my loss', or needs to check whether a negotiation/market/policy situation is truly zero-sum before designing strategy. Do NOT activate when: the situation is already confirmed zero-sum (chess, derivatives, fixed-license auctions) and diagnosis is complete — go straight to minimax; or the question is already framed at the equilibrium level — use nash-equilibrium directly.
