From the speaker
- Pelrine
- a top AI system
- 14 games to 1
- a 15 match series
- a strong amateur
Our interpretation
- The claim concerns the recently reported series following the late-2022 research, completed before publication.
- Top means a leading Go-playing system under ordinary play. It does not mean unbeatable against specially developed attacks.
- The score describes the reported set of fifteen games, without assuming a formally organized tournament.
Counts as supported if: Records or reliable reporting establish that amateur Kellin Pelrine won fourteen and lost one of fifteen games against a leading Go AI.
Counts as contradicted if: Reliable records establish a different score, a different player, professional status, or an opponent that was not a leading Go system.
Retrospective: these criteria were written after the outcome was public.
Current assessment
Was it true for the period described?
Outcome: Supported

Scored on a plain reading. The speaker named no measure for this claim, so it was judged on the reading an informed reader would take, stated below under our interpretation. Both reviews had to find that reading fair.

Rationale
The reported amateur player and 14–1 score are confirmed. The result concerns adversarial play against a leading system, not general superiority at Go.
Limitations
- The accessible news republication appeared one day after Marcus's post.
- The evidence does not establish that this was a formally organized match.
Evidence (1 item)
Supports the claim: Financial Times, republished by Ars Technica,
he won 14 of 15 games
Why it matters here: The report identifies Pelrine as an amateur and confirms the score against a leading Go system. The researchers' paper corroborates the result.
