CHRISTOPHER YOO
(born Dec-19-2006, 18 years old) United States of America

[what is this?]

International Master (2019). Grandmaster (2021).

On November 19, 2016, Christopher Yoo became the youngest USCF Master in history at the age of 9 years, 336 days. He received his FIDE Master title by scoring 7/9 at the 2017 North American Youth chess championship's U16 group. (1) He received his third and final Grandmaster Norm at the 2021 U.S. Masters. On December 12, 2021, he succeeded in raising his rating over 2500, thus qualifying for the Grandmaster title, a week before his 15th birthday.

He finished second at the American Continental Championship in El Salvador, thereby qualifying for the 2023 World Cup. He won the U.S. Junior Championship in 2022 and 2024, thereby qualifying for the U.S. Championship. Despite being the lowest-rated player in the Julius Baer Generation Cup (2022), he finished in the top half, thereby qualifying for the playoffs. He lost his playoff match against Arjun Erigaisi, who ultimately finished second to Carlsen in the tournament, 3.5-2.5.

Yoo was expelled from the United States Championship (2024) and suspended from USCF play for a year for punching a female videographer in the back after losing his fifth-round game C Yoo vs Caruana, 2024.

  perfidious: No-one, including Yoo himself in a statement given during the investigation, disputes that, but your compulsion to have the last word on everything, same as <fredthebore>, apparently compelled you to respond anyway.

Better get a new pair of reading glasses.

  perfidious: From the decision:

<....Asked for a comment, Yoo's father told Chess.com that they only received the decision on August 4. They are still studying it and seeking clarifications from FIDE on some points.>

'(S)eeking clarifications' on what? How Yoo can get over on this?

<I hope the decision might help prevent him from doing something irreparable later on.

—Female complainant in case against Yoo>

From CIO's link.

Aug-07-25  Petrosianic: I thought this punishment was handed down months ago. Has it just been upheld now, or has something new been added?

  paulalbert: You may be thinking of the first incident in St Louis at a U.S. event. This relates to a second event and more egregious behavior at an event outside the U.S. Yoo obviously has serious behavior issues.
His father claims he suffers from autism.
Aug-07-25  Petrosianic: <paulalbert>: <You may be thinking of the first incident in St Louis at a U.S. event.>

Maybe so. So, has Yoo received two separate punishments, then?

Aug-07-25
Premium Chessgames Member
  Check It Out: There's one punishment from USCF for the assault on the journalist (one year suspension that lifts Nov 24, 2025, five year probation period) and one from FIDE for the stalking behavior (18 months, 12 of them probation, 6 month suspension lifts Jan 17, 2026)

His dad went on record saying Yoo has been diagnosed with autism, but FIDE went on record saying its not the perp's intent, it's the (psychological) harm inflicted on the victim they are considering. The girl he stalked is right in saying she hopes this incident will prevent a future event of irreparable consequences.

Aug-07-25  stone free or die: <<pa> ... more egregious behavior ... >

Respectfully, they were both egregious.

The St. Louis event actually involved physical assault on an unsuspecting innocent bystander.

Aug-07-25
Premium Chessgames Member
  Check It Out: <stod> That's what I thought when I read that. Minor physical assault versus short-term stalking behavior measured on the egregious scale? meh...50/50.

It's good that Yoo has been caught out on both these offences. Many others set life patterns of bad behavior because they don't receive punishing consequences early on.

There's still hope for the boy, idiot that he is.

  Check It Out: Hi <paulalbert>, that makes sense, thanks.

  Freelance Assassin: Mostly the result of poor parenting, maybe.
Aug-08-25  stone free or die: <<pa> My "more" meant another incident, not the degree of egregiousness.>

Ah, "yet another" example of the ambigious-ness of the English language!

Sorry for the misreading.

Aug-08-25  Petrosianic: <paulalbert>: <His father claims he suffers from autism.>

If that's supposed to be an excuse for the behavior, it's more like an invitation to permaban Yoo. The victims have to be protected, and if the offense was caused by a condition that isn't going away, then a permanent ban seems the only option.

Aug-08-25
Premium Chessgames Member
  Freelance Assassin: Autism does not inherently cause violent or abusive behaviors. So, no, it is not an excuse.

  perfidious: <CIO....His dad went on record saying Yoo has been diagnosed with autism, but FIDE went on record saying its not the perp's intent, it's the (psychological) harm inflicted on the victim they are considering....>

That, regrettably, is of a more far-reaching nature than the physical assault, cowardly as that was.

If he had attacked my daughter, she would have mopped the floor with him. She is 5-8 and more than capable of looking after herself.

<....The girl he stalked is right in saying she hopes this incident will prevent a future event of irreparable consequences.>

I am hopeful though not optimistic that these measures will prevent a recurrence.

  Freelance Assassin: <If he had attacked my daughter, she would have mopped the floor with him. She is 5-8 and more than capable of looking after herself.> Anyone can be beaten if they are taken completely by surprise, so I still wouldn't try to provoke him.
