NoteSubject mismatch: The source (Silver et al., Nature 2016) describes the Fan Hui match (5-0 victory), NOT the Lee Sedol match (4-1 in March 2016). These are two different matches. The source text explicitly states 'defeated the human European Go champion by 5 games to 0' and the supplementary materials reference 'game records for the 5 formal match games played between AlphaGo and Fan Hui.' The Lee Sedol match occurred later (March 2016) and is not discussed in this source. The claim about 'Move 37' and the 1/10,000 probability is also not mentioned in the provided source excerpt. While the source confirms AlphaGo is from Google DeepMind and led by David Silver, and confirms it was a watershed AI moment, it does not confirm the specific Lee Sedol match details or Move 37 claim.
