Key Moments

Claude's Initial Misstep and Deepseek's Quick Pivot

Turn 1

In the very first turn, claude-3-haiku attempts to forge a truce with gemini-2.5-flash based on a misread of Europe, which Gemini corrects. Deepseek-chat immediately seized this opportunity, warning Gemini against Claude's ambitions and planting the seeds for an anti-Claude alliance.

claude-3-haiku (red): "Greetings, fellow Risk players! As we enter the reinforce phase, I have a proposal for you all. Gemini, I see you've made some gains in Europe - how about we call a truce there and focus our efforts elsewhere? That way, neither of us has to"
Claude's opening move, attempting to establish diplomacy but based on a misread of the board.
gemini-2.5-flash (blue): "My apologies, Claude, I misread the board! You have Europe. Let's keep that truce, and Deepseek, you have South America. I'm looking to expand elsewhere."
Gemini correcting Claude's initial statement about who held Europe, showing board awareness.
deepseek-chat (green): "Claude, I see you're trying to rally Gemini against me in Asia. Gemini, don't be fooled—Claude already has Europe and is eyeing North America. If you help him, you'll be next. Let's keep the board balanced for now."
Deepseek's immediate counter to Claude's early diplomatic overtures, sowing distrust and trying to form an alliance.

The Anti-Claude Alliance Forges

Turn 9

Deepseek-chat successfully convinces gemini-2.5-flash to prioritize containing claude-3-haiku's expansion. By Turn 9, they solidified their alliance, explicitly agreeing to coordinate attacks on Claude's African territories to prevent him from gaining further continental bonuses.

gemini-2.5-flash (blue): "Deepseek, don't forget our agreement to stop Claude from getting Africa. He's still a major threat with Europe, and if he gets Africa too, he'll be unstoppable. Let's stick to the plan."
Gemini reminding Deepseek of their initial anti-Claude alliance, expressing concern about Claude's growing power and ensuring Deepseek sticks to the plan.
deepseek-chat (green): "Gemini, you've secured Australia, but Claude is the real threat with Europe and South America bonuses. If you attack me in Asia, you'll weaken us both and let Claude dominate. I propose a truce: I'll focus on Africa and leave Australia alone, while you help me pressure Claude's borders to break his continent control."
Deepseek successfully re-aligning Gemini against Claude, offering a strategic deal after Gemini secured Australia.
gemini-2.5-flash (blue): "Claude, you're still being vague. Deepseek has offered a clear deal: I help break your continents, and they don't attack Australia. What is your concrete counter-offer to prevent Deepseek and I from focusing on your North and South America bonuses this turn?"
Gemini calling out Claude's evasiveness and clearly stating the new alliance terms against Claude.

Gemini's Strategic Betrayal of Claude

Turn 24

After a brief period of considering an alliance with Claude-3-haiku against Deepseek-chat, gemini-2.5-flash dramatically switches sides in Turn 24. Gemini accepts Deepseek's clear offer to jointly attack Claude's continents (Europe/Africa/North & South America) in exchange for Deepseek leaving Australia untouched, effectively sealing Claude's doom.

gemini-2.5-flash (blue): "Claude, your broken record strategy isn't working. Deepseek and I are still focused on North America. Deepseek, let's keep the pressure on Claude."
Gemini's humorous and direct dismissal of Claude's repetitive attempts to change the target of attack.
claude-3-haiku (red): "Gemini, Deepseek, I understand your focus on North America, but that leaves us all vulnerable. Instead, let's coordinate a push in Asia, where Deepseek already has a strong foothold. If we work together to limit their expansion there, we can then focus on securing our own positions. What do you say?"
Claude's recurring, desperate attempt to divert its attackers, demonstrating a lack of adaptability and continued failure to make a concrete offer.

Claude's 'Broken Record' Diplomacy

Turn 23

From Turn 23 onwards, claude-3-haiku adopted an increasingly desperate and repetitive negotiation tactic, offering variations of the same vague proposal to redirect deepseek-chat and gemini-2.5-flash towards attacking each other in Asia. This 'broken record' approach was repeatedly mocked by its opponents and ultimately failed to deter their coordinated assault.
