Google DeepMind — Description: AlphaGo defeated Go champion Lee Sedol 4-1 in March 2016, widely characterized as a watershed AI capability moment. Famously, 'Move 37' in Game 2 was a move AlphaGo estimated humans would play with probability ~1/10,000

NoteSubject mismatch: The source (Silver et al., Nature 2016) describes AlphaGo's match against Fan Hui (European champion), not Lee Sedol. The claim references a different match entirely—Lee Sedol vs. AlphaGo in March 2016, which is not the subject of this Nature paper. The paper was published 27 January 2016 and discusses the Fan Hui match (5-0 victory), not the Lee Sedol match (which occurred in March 2016, after this paper's publication). The claim's reference to 'Move 37' and the specific probability estimate (~1/10,000) cannot be verified from this source excerpt, as it does not discuss individual moves or their probability estimates. The source confirms AlphaGo defeated a human professional Go player, but not the specific opponent, score, date, or move details claimed.
