Why Chen is the favorite to win the men’s figure skating gold medal in Pyeongchang.
Figure skating is a sport that exists in small margins. Skaters spend around seven minutes on the ice over two nights of events. The difference between silver and gold can come down to decimal points. When they jump, they cram three to four revolutions into less than two-thirds of a second.
It’s in these small spaces that American skater Nathan Chen has blown up the sport over the past couple of years.
At the 2017 US Figure Skating Championships, where Chen easily won gold, the second-place skater was a previously unheard-of 55 points behind him. Chen successfully landed five quadruple jumps during his free skate and set the skating world ablaze; no one had even been able to hit five quads in one program before.
That night, his fellow American skaters gave him standing ovations for his performance. But beneath this history-making, speech-stopping moment was something even more impressive: This unrivaled skate, as astounding as it was, offered just a glimpse of Chen’s potential.
Just over a year has passed since that jolting performance, and Chen’s career is no longer in the phase where he shocks or surprises with his brilliance. Now brilliance and dominance are expected — the last time he lost to anyone on the ice was in 2016.
In a sport that’s known for unpredictability, Chen has become a chilling constant. And he’s now a favorite to win Olympic gold. Here’s what makes the quad king so special.
To fully comprehend what makes Nathan Chen so good, you have to take a step back and look at the mildly boring side of figure skating — the numbers and the scoring.
The current figure skating scoring system is highly dependent on counting each and every technical element. For a thorough explanation of how it works, check out Vox’s explainer and video on all the nitty-gritty details. But essentially, what it comes down to is that the difficulty level of quadruple jumps makes them worth a whole lot of points, even if a skater doesn’t perform them that well. And that sometimes leads to situations where a skater who falls while performing a quadruple jump still outscores a skater who lands a perfect triple.
In plain English, quads landed cleanly can lead to super-high technical scores — especially if they’re performed during the second half of a free skate, when they’re eligible for a 10 percent bonus.
But what helps set Chen apart is not only his ability to successfully land quads in the first place, but his ability to successfully land several different types of quads.
That’s because of rules that not only limit the number of jumps a skater can do in a single program, but also prevent skaters from performing the same jumps over and over. In the free skate, for example, men are allowed a maximum of eight jumping passes (women are allowed seven), and skaters are not allowed to repeat a standalone triple or quadruple jump more than twice (more repetition is okay if the jumps are performed as part of a combination with other jumps).
Chen is the only skater competing today who can land five different types of quads. And since there are only six types, and no one has yet landed the quad axel, this is a major advantage. His variety and consistency of execution give him greater potential than almost any other skater to achieve a higher technical score than his competitors.
For example, Japanese skater Yuzuru Hanyu, one of Chen’s rivals and the reigning Olympic gold medalist in men’s figure skating, can also land several different quads — but so far, he’s maxed out at performing four of them. Which means Chen’s young history of packing five quads into one program is now the standard to beat (and there are rumors that he’s toying with putting a sixth quad into his program).
Chen is also able to consistently land the highest-scoring quad of the moment, the quadruple lutz, a feat that not all of his rivals can claim. Chen usually places his quad lutz at the beginning of his programs, then tacks on a triple toe loop, as he did during the 2017 International Skating Union Grand Prix Final in December:
When assessing any jump, figuring skating judges look for full rotations, good height, a tight air position, and a clean entry and landing, among other details — and as seen in the GIF above, Chen’s quadruple lutz seems to check all those boxes. The judges at the Grand Prix agreed: A quad lutz–triple toe loop combination has a base value of 17.90 points, and in this particular instance, Chen’s execution of the combo earned him a grade of execution (GOE) score of 2.0 points (out of a high of 3.0), for a total of 19.90 points.
For context, a standalone triple axel where a skater earns a perfect 3.0 GOE is worth 11.5 points, and even difficult combinations where a triple axel is paired with another triple or double jump tend to top out around 16.5 points (including a 10 percent bonus) — so 19.90 points for a single jumping pass is astronomically high. But astronomically high base values are pretty routine for Chen, as he regularly crafts his programs in a way that maximizes his scoring potential. This strategy usually means that if he lands every jump cleanly, he’s essentially unbeatable. It also means that his base scores are often high enough that he still has a good chance of winning even when he doesn’t skate his best.
To better illustrate that, here are Chen and Hanyu’s scoresheets for their respective free skates during the 2017 International Skating Union Four Continents Championships, with the total base value of their respective technical elements circled in red. Chen’s elements boast a combined base value of 106.48 — more than 13 points higher than Hanyu’s 93.20:
And if you look at the two skaters’ GOE columns, you’ll see a few negative scores that add up to about 3.66 points in GOE deductions for Chen, compared to Hanyu’s total of 0.06 points in GOE deductions.
The differences in Chen and Hanyu’s GOE scores indicate that Hanyu skated a cleaner program overall and Chen skated pretty poorly. That’s what allowed Hanyu to beat Chen’s free skate score by just over 2 points — note Hanyu’s “Total Segment Score” of 204.34, compared to Chan’s 206.67. But Chen ended up winning the overall competition because he beat Hanyu in the short program by about 6 points. His final score for the short program and free skate combined was 307.46, almost a full 4 points higher than Hanyu’s 303.71.
Essentially, because Chen is capable of landing so many quads in one routine, he’s really only beatable if his competitors skate at the absolute top of their game and he skates poorly in both his short program and his free skate — and that hasn’t happened yet. He’s currently the only undefeated men’s skater in the 2017-’18 figuring skating season, having won the International Skating Union Grand Prix Final, Skate America, the Rostelecom Cup, and the US Classic.
Chen has improved in two major ways since he burst onto the figure skating scene in 2016, with most of his progress taking place over the past year.
His first improvement was a strategic one, in that he started regularly clustering the jumps in his free skate so that they would largely fall within the second half of the program. This approach allows him to increase the base value of each “back half of the program” jump by 10 percent, because it takes advantage of a bonus that rewards skaters for continuing to complete difficult skills even as they grow more tired.
If you look at a typical figure skating scoresheet, jumps placed in the second half of a skater’s program are typically marked with an X. Here’s Chen’s scoresheet from the 2017 US Figure Skating Championships, which took place in January of that year:
Note the four X’s to the right of the “Base Value” column, which show that Chen earned the 10 percent bonus for four different elements: his triple axel (“3A”), quadruple salchow (“4S”), triple lutz (“3Lz”), and triple flip–triple toe loop combination (“3F+3T”).
Now here’s his scoresheet from the 2017 International Skating Union Grand Prix Final, which took place at the end of the year, in December:
Though a few negative GOE scores reveal that Chen didn’t skate particularly well, this time there are five X’s instead of just four; he earned the 10 percent bonus on a quadruple lutz (“4Lz”), a quadruple lutz–toe loop–double salchow combination sequence (“4T+1Lo+2S”), a quadruple toe loop (“4T”), a triple axel (“3A”), and a triple lutz (“3Lz”).
