Diplomacy is a masterclass in strategic negotiation and psychological warfare, where victory hinges not on luck but on a player’s ability to manipulate alliances, predict betrayals, and balance cooperation with self-interest. Set in pre-World War I Europe, the game strips away random elements like dice or cards, forcing players to rely solely on verbal agreements, tactical positioning, and calculated deception. Each turn revolves around two phases: secret negotiations, where players forge fragile partnerships, and simultaneous order resolution, where written commands determine territorial gains or catastrophic failures. The absence of enforced trust means every promise is a potential trap, and every ally could become a backstabber. Successful players master the art of long-term planning—securing key supply centers, disrupting enemy logistics, and exploiting geopolitical chokepoints—while navigating the emotional tension of broken alliances. Ultimately, Diplomacy transcends mere gameplay; it mirrors real-world politics, revealing how power dynamics evolve when ambition collides with human relationships.

And I think AI may do better in the game and I wanna have a test between AIs-including the most famous some,like ChatGPT,Phi4,Llama,Deepseek,Tongyi...Is that possible to have a competition between AIs?
