In a video that was uploaded to YouTube last week, a player from the UK who goes by the name of “Paddy” posted a series of chess pieces moving along the board.
The player was also posting a series that appeared to be taken from the chess website World Chess, which has a reputation for being a cheat site.
In the video, a woman is seen standing in front of the computer, taking notes on the board while someone moves chess pieces.
“Oh, I love that,” she says.
“It’s really cool.”
The video has received nearly 4 million views since it was posted on Wednesday.
In the past, it has also been viewed more than 2 million times.
Paddy said in a YouTube message that he uploaded the video as part of his work with his son, a teacher.
“I am a big fan of the chess board game, and the whole idea of creating new pieces for this game is quite cool,” he said in the message.
“To be honest, it’s just something I did to make myself happy and to play chess with my kids.”
But a spokesman for the chess organization that runs World Chess said he wasn’t aware of any such cheating.
“We do not condone any cheating on our board games, and we do not believe the video was captured by a professional chess player,” a spokesman said in an email.
The Chess Federation of Canada said it was “shocked” by the video.
“Our organization is working closely with police, the authorities, the video creator and the chess world,” a statement said.
“The Chess Board of Canada has zero tolerance for cheating and will work closely with authorities to determine the truth of this story.”
