前幾天在「用情趣用品在西洋棋比賽裡面傳遞摩斯電碼作弊」這篇裡面有提到目前對 Hans Niemann 的調查都還在進行，現在 Chess.com 先丟出調查報告了：「Hans Niemann Report」，另外 Hacker News 上也有討論：「The Full Chess Cheating Report of Hans Neiman (chess.com)」。
PDF 的 summary 開頭就提到分析了線上的對奕記錄作弊的比率比起 Hans Niemann 所承認的高很多：
We present evidence in this report that Hans likely cheated online much more than his public statements suggest. However, while Hans has had a record-setting and remarkable rise in rating and strength, in our view there is a lack of concrete statistical evidence that he cheated in his game with Magnus or in any other over-the-board (“OTB”)—i.e., in-person—games. We are presenting our findings here and will cooperate with FIDE on any further investigation.
除了棋局上的記錄，在後面「How Cheat Detection Works」這個章節也提到了很多額外的 event log，像是視窗切換之類的資訊。
然後 Chess.com 也宣佈撤回賽事邀請，並且停權：
We uninvited Hans from our upcoming major online event and revoked his access to our site based on our experience with him in the past, growing suspicions among top players and our team about his rapid rise of play, the strange circumstances and explanations of his win over Magnus, as well as Magnus’ unprecedented withdrawal. In order to have more time to investigate the OTB situation and our own internal concerns, we uninvited Hans from our event and prevented his access to Chess.com. We are open to continuing a dialogue with Hans to discuss his status on Chess.com.
先有一個組織跳出來下刀了...
