Christopher Yoo Breaks 2500 FIDE; Becomes GM-Elect

It will be a very happy 15th birthday indeed for Christopher Yoo.

With GM three norms under his belt — the Memorial Day 2021 CCCSA GM Norm Invitational, the Labor Day 2021 CCCSA GM Norm Invitational, and the 2021 US Masters — Yoo found himself five rating points shy of the 2500 barrier required to become a Grandmaster after his performance at the US Masters in Charlotte.

Yoo’s father, Young-Kyu Yoo, asked Facebook friends to suggest possible events where Christopher might be able to hunt down those five final points, allowing him to become a GM-Elect before his fifteen birthday. William Graif suggested the Edward Lasker Memorial / Marshall Chess Club Championship, held over two weekends at the historic Marshall Chess Club in New York City.

Only able to play the first weekend due to scheduling conflicts, the pressure was on: could Yoo avoid any “Botez gambits” and pick up those five final points in just five rounds?

This happy face tells the tale better than words ever could:

Scoring 4½/5, including wins over two FMs and a draw with GM Brandon Jacobson, Yoo appears to have gained 5.2 rating points, putting him just over the 2500 mark, and earning him the GM title at 14 years and 51 weeks — subject to FIDE confirmation, of course.

Here are two games from the event. The first, against veteran FM Konstanin Dolgister, features a tactical flurry worth of a new grandmaster, while the second, against Zachary Tannenbaum, gave him the final point needed to earn his title.

Congratulations to GM-Elect Christopher Yoo!

For those interested in following in the Yoo’s path to the top, here’s some advice from Christopher’s father, Young-Kyu Yoo:

Here is my advice to parents. You might have a coach of master strength or lower until about 2000. We had Wei Liu, who as far as I know has never played tournament chess, but who coached his own son and daughter to master strength, until Christopher was about 1800/2000.

Then, if your kid is ambitious, transition to a coach of GM strength. GM Khachiyan was that coach for us. If your kid makes master and seems to be on track to get to GM, consider adding an openings coach (GM Avrukh for Christopher) until your child can do openings on their own. Sometimes, however, your regular coach can also be the openings coach.

If the child becomes an IM or stronger and seems capable of even higher levels, find a coach who can best guide them to the upper levels. That was GM Aagaard and then (on GM Aagaard's suggestion) GM Shankland for Christopher.

Along the way, if your child shows promise, your child may become eligible for free training. In the U.S., we have the US Chess School that provides free chess camps to strong juniors. The Kasparov Chess Foundation provides free training to a few select kids in the US and, more recently, in Europe and elsewhere. Through the KCF we've been lucky to get training from GM Chernin and GM Onischuk.

Recently, the FIDE Online Academy has become available to strong kids around the world. Unfortunately, their class hours don't work for us here in California and Christopher will likely have to drop out.


Congratulations to Christopher on what I hope will imminently be a GM title, but there ain’t no such thing as a GM-Elect. One either has the title or one does not, and one does not have it until FIDE awards it.

Congratulations Christopher! I was at the tournament and saw your games against Dolgitser, Tanenbaum, Jacobson, etc. Very impressive!
