If a large language models beats a super grandmaster (Classic elo of above 2,700) while playing blind chess by 2028, this market resolves to YES.

I will ignore fun games, at my discretion. (Say a game where Hiraku loses to ChatGPT because he played the Bongcloud)

Some clarification (28th Mar 2023): This market grew fast with a unclear description. My idea is to check whether a general intelligence can play chess, without being created specifically for doing so (like humans aren't chess playing machines). Some previous comments I did.

1- To decide whether a given program is a LLM, I'll rely in the media and the nomenclature the creators give to it. If they choose to call it a LLM or some term that is related, I'll consider. Alternatively, a model that markets itself as a chess engine (or is called as such by the mainstream media) is unlikely to be qualified as a large language model.

2- The model can write as much as it want to reason about the best move. But it can't have external help beyond what is already in the weights of the model. For example, it can't access a chess engine or a chess game database.

I won't bet on this market and I will refund anyone who feels betrayed by this new description and had open bets by 28th Mar 2023. This market will require judgement.

• Update 2025-21-01 (PST) (AI summary of creator comment): - LLM identification: A program must be recognized by reputable media outlets (e.g., The Verge) as a Large Language Model (LLM) to qualify for this market.

  • Self-designation insufficient: Simply labeling a program as an LLM without external media recognition does not qualify it as an LLM for resolution purposes.

• Update 2025-06-14 (PST) (AI summary of creator comment): The creator has clarified their definition of "blind chess". The game must be played with the grandmaster and the LLM communicating their respective moves using standard notation.
