There is a scandal brewing in the chess world. Seinfield Cup in St. Louis is happening, one of the bigger tournaments each year. Magnus won in the first round against Nepo, and then had white against a late-replacement in the tournament, Hans Niemann. He's a very odd character. He's known for being a bit of a bad boy (lots of confrontational interviews and streaming statements), but an up and coming strong player. He managed to beat Magnus with the black pieces. The game didn't look especially suspicious to me, largely because Magnus played pretty poorly, but Magnus thought otherwise, and resigned from the tournament saying that he'd get in trouble if he explained why. Some GMs stated that young players should be given a chance, and others (including Nepo) made some sly comments that Niemann's play was "more than impressive." Niemann also has a repuation for cheating, being banned from chess.com twice, and some GMs booting him out of their online money matches. Cut to yesterday, and all eyes were on Niemann versus Firouzia, who just beat the everliving piss out of everyone at the world blitz-rapid tournament, and is pretty clearly the best player in the world of the new generation. This game was definitely suspicious. Niemann played a move that was VERY much an engine move, offering a piece for a position that no commentators or GMs could see why it was good. There was no immediate forced mate. But the engines loved it, and there was an insane line 12 moves down the way that could force a win. Firouzia declined the sacrafice because he had no clue what was going on, and white had a much better game for a while. It wound up going to a draw, and Niemann told Firouzia about a line he considered which would have won nearly by force, and also no commentators saw coming, even in hindsight. The interview afterwards with Niemann explaining the game was doubly-suspicious. He claimed to have studied all of the lines involved the morning of, despite never playing in this particular opening variation before, and the 2600 that was going over the game with Niemann clearly had a much better understanding of the position (when they turned the engine evaluation off.) He couldn't even spell out the entire line that accepting the initial piece sac involved, blundering repeatedly in the post-mortem. I think it's pretty clear shenanigans are involved, but how he's cheating is going to be tough to prove. I think it might just take the players refusing to play at events he's invited to to put a stop to it. I don't normally like listening to Nakamura much because he's too awkward to listen to in large doses, but for evaluating if top-level players are cheating, it makes more sense to listen to him than anyone else chiming in.
