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.

  ketchuplover: Sardinia conqueror!
May-11-25  fabelhaft: <It started after the Grenke Open, at a party where there were several players, including Christopher,” the female player's written complaint alleges, “We met there. He asked us for some group pictures. We accepted. During the party, I found his behaviour uncomfortable. The day after, he messaged me, so I blocked him on social media. At the Sardinia World Chess Festival, while I was having lunch with friends at the hotel restaurant, he approached us out of nowhere, spoke to us uninvited, and suddenly caught my hand while I was eating.”

”On Saturday, May 3, after lunch, he followed my friends and me to our room area. I went into my room and shut the door. He stayed outside, knocking several times and even said ‘housekeeping’ through the door. He stayed there for 10 minutes before leaving. He also touched my shoulder on another occasion. None of this was welcome or appropriate. My friends repeatedly asked him to leave us alone, but he didn’t stop.”

The complaint also mentions that Christopher remarked: ‘I don't respect 1950 players. Your brain doesn’t know how to move the knight.’

The female player called herself “lucky” to have been surrounded by friends throughout the tournament and shuddered to think what might have happened if she had been alone. “At a certain point, I couldn't walk around the resort on my own without fear of running into him.”

The female player’s account was corroborated to HT by an International Master who was with the complainant, along with a few other friends, at the Sardinia World Chess Festival held from April 26 to May 4. “I was there and I saw how uncomfortable Christopher made her feel, and the sort of pressure he was putting on her – like touching her and following her to her room,” said the IM. “At one point, he joined us at the bar where some of us (including the complainant) were having a drink. We asked him to leave because we were not comfortable with his behaviour towards her, but he just refused.”>

  perfidious: ‘I don't respect 1950 players. Your brain doesn’t know how to move the knight.’

Even if Yoo engaged in none of the misconduct as alleged, this statement is pathetic.

What follows next, the same type of de rigueur non-apology apology as this kid issued after St Louis?

  tamar: His dad was with him in Sardinia, as seen in this clip of ceremony and interview https://m.youtube.com/watch?v=W0CLo...

He has hired a mental coach for him, but notice how uncomfortable Yoo appears when his father is speaking about him. It is similar to his agitation in the game which triggered his acting out in St Louis.

Whatever his maturity level, his chess is on a crazy upswing. He won Sardinia, and also Freestyle Friday by 1.5 pts over Hans Niemann and Vincent Keymer.

May-12-25  Albertan: Yoo handed 60 day suspension by the FIDE:

https://www.chess.com/news/view/chr...

May-12-25  stone free or die: <Given the gravity of the allegations and the ongoing proceedings, the Chair of the EDC has enacted a temporary suspension of GM Yoo to safeguard the integrity of the investigative process. Both GM Yoo and the USCF have been formally notified of this decision. The suspension may be extended if a final resolution is not reached within the initial 60-day period.>

  Check It Out: You mean he learned how to be a douche? You're right.
May-13-25  stone free or die: It's in many of the articles linked previously, but this new <CB> article gives a chance to quote it explicitly here - i.e. USCF asked FIDE to enforce it's year-long ban on Yoo internationally:

<Under Article 26.12 of the FIDE Charter, national sanctions may be extended internationally if a member federation requests it and if the decision complies with fundamental legal principles and fair trial standards. In line with this, the USCF formally submitted a request for FIDE to recognize and globally enforce its ban, pursuant to Article 4.15 of the FIDE Ethics Code. This request remains under investigation.>

https://en.chessbase.com/post/chris...

From what I've read, <FIDE> would have done him a service not letting him play in order to work on his "issues".

It's clear people with mental health issues such as his can lead to a toxic environment wherever they go, not just for others but for themselves - so long as untreated and unchecked.

Jul-01-25  Petrosianic: Yoo's USCF suspension has been expanded to include FIDE events.

https://ethics.fide.com/wp-content/...

Jul-01-25  stone free or die: Given that the US event was also a FIDE zonal, that the facts were undisputed, and that the USCF request was sent on March 27th of this year it strikes me that FIDE's decision is woefully dilatory.

Almost to the point of neglect, especially given the events at Sardina, and the speed of FIDE's disciplinary action there.

.

Jul-01-25  Petrosianic: Yeah, they did kind of Slow-Boat-to-China it, but at least it did finally arrive.

  MissScarlett: From the FIDE statement: <4.1. On October 16, 2024 the Respondent Christopher Yoo punched Ms. Jordan Hallemann (a broadcast team member) on her upper back as he walked past her, unprovoked, after losing his game in round five.>

Noted for the historical record.

  perfidious: Even if Yoo had, in some measure, been provoked by Ms Hallemann, his actions were inexcusable and were those, as <CIO> eloquently put it, of a douche.

  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.

<<perf> No-one, including Yoo himself in a statement given during the investigation, disputes that, ...>

You mean no-one but yourself:

Better get a new pair of reading glasses.

As in not.
