The latest generation of reasoning LLMs perform worse at #Chess compared to previous models. o3 & o4‑mini vs weak Stockfish: illegal moves in 88% & 94% of 67 games. o3 breaks rules in 4 moves; both resigned while winning. Worse than GPT‑3.5‑turbo‑instruct (1750 Elo)

Real position coming from an online real game in #Chess960 I just played. Is it a draw? -0.3 according to Stockfish, but no clear plan. Chess engines are notoriously bad at resolving/assessing fortress-like position. But is it such a case? What do you think? #ChessEveryWhere

Metamorphic Testing, Reproducibility & a Curious Chess Engine Mystery
We replicated a study that found inconsistencies in how Stockfish (the best engine in the world) evaluates mirrored positions. But the key issue? Depth sensitivity.🧵⬇️
