A CHESS grandmaster QUIT after he lost out on a share of a £1million prize fund following a never-before-seen mistake.
Poland’s Jan-Krzysztof Duda sensationally resigned after making a slight mishap during a last-16 clash this week.


Duda faced Nodirbek Abdusattorov at the Esports World Cup on Thursday.
Duda, 27, and Uzbekistan’s Abduattorov, 20, drew twice during regular games before Duda abandoned the game in the Armageddon.
It came after the rarest of mistakes – an accidental computer MOUSE SLIP after making his fifth move on the board.
The commentator couldn’t believe it and he roared: “Oh my gosh no.
“For the first time a mouse slip instantly decides a game at the ESports World Cup.
“This is an occupational hazard for ESports all over the world but this is the first time we’ve seen this in such a crunch situation.
“This, no-one was expecting.”
While his fellow announcer said: “Unbelievable”.
In online chess, a slip refers to an unintentional move caused by a player’s mouse, often due to misclicks or dragging a piece to the wrong square.

There isn’t a universal rule dictating how to handle them in Esports, but rather a mix of etiquette and practical considerations.
Some players choose to accept the mistake, continue playing, or even resign, while others might offer a draw or accept a takeback.
But Duda quit despite the game being the difference between winning $65,000 or at least $85,000 in the quarterfinals.
The first place prize for the tournament is $250,000, with a combined prize pool of $1.5 million.
After his shock win, Abdusattorov said: “It’s quite unbelievable right now.
“In general, I am very happy to qualify for the final eight. It’s going to be even tougher in the Finals.”
Fans were quick to have their say on social media.
One said: “Bro will regret this his entire life.”
