Maxim Alexandrovich Dlugy[1][2] (born January 29, 1966) is an American chess player with the FIDE title of Grandmaster.

[4] He was awarded the Grandmaster title in 1986 for his result at the World Chess Olympiad in Dubai, United Arab Emirates.

Dlugy was one of the campaign managers along with Garry Kasparov for Anatoly Karpov when he ran for FIDE President in Khanty-Mansiysk, Siberia, in 2010.

[14] On two separate occasions in 2017 and 2020, Dlugy was suspected of, and later admitted to, having cheated himself in a Titled Tuesday online tournament run by Chess.com.

The incident received renewed attention after Magnus Carlsen referenced it during the Carlsen–Niemann controversy, claiming that Dlugy had previously served as a coach of Hans Niemann.

[15][16][17] Later, Vice published an article where Chess.com released e-mails showing that Dlugy had confessed to cheating multiple times on Chess.com and had to be banned entirely from all events with cash prizes.
