  value: moderate
additional property: Likely AI Summary
  type: PropertyValue
  value: Ablating one attention head in a chess transformer causes it to fail on Morphy’s queen sacrifice — evidence that individual heads encode specific strategic knowledge.
additional property: Narrative Frame
  type: PropertyValue
  value: A grassroots, hacker-style discovery revealing fundamental mechanistic insight about how transformers 'think' about chess.
additional property: Missing Context
  type: PropertyValue
  value: No information about model size, training corpus, evaluation protocol, or whether the ablated head is uniquely critical across positions; No discussion of confounding factors like tokenization, positional encoding, or random seed effects
additional property: How the Spin Works
  type: PropertyValue
  value: The story emphasizes growth, adoption, funding, speed, or market movement to make the subject feel increasingly important. Watch for loaded terms such as stops finding, Morphy's queen sacrifice. The distribution reads as community sharing. A pressure point: No information about model size, training corpus, evaluation protocol, or whether the ablated head is uniquely critical across positions.
