Ah, Wang Chuqin’s serve has been attracting a lot of buzz for a while, especially since he started sweeping titles in late 2022. Usually, I relish a bit of sports drama, whether applauding brilliance or roasting athletes or teams like a backyard BBQ. But when people cry foul, claiming Wang’s making the illegal serves, by whipping out livestream screenshots, my filmmaker brain kicks into overdrive. 🤯 It’s time to break down why clicking pause and yelling “Gotcha!” isn’t the slam-dunk argument they think it is.

The Optical Illusions That Trick Us All
Let’s start by busting the myth that what you see on screen is the gospel truth. Cameras are sneaky little magicians, bending reality in ways that can fool even the sharpest eyes.
How Cameras Distort Reality
- Lens Distortion: Camera lenses can sometimes be like funhouse mirrors, bending light, warping straight lines, and stretching or shrinking objects. Even the best tech can’t fully correct this, and it only gets worse when combined with other visual quirks.
- Perspective Distortion1: Cameras flatten a 3D world into a 2D image, and in the process, everything gets skewed: object size and position, camera-subject distance, and spatial relationships between objects. Focal length plays a huge role here. There’s a widely accepted theory among photographers that a 50mm focal length produces images closest to what the human eye sees. The farther you move from 50mm, whether to shorter or longer focal lengths, the more distortion or compression affects the footage and images.
- Eg. 1: Ever seen a Hitchcock dolly zoom? A dramatic stretching or shrinking effect happens when a camera changes its focal length while moving closer or further from the subject. It’s cool for storytelling in movies, but may unintentionally warp perception in sports broadcasts.
- Eg. 2: Imagine two identical jars sitting 16” apart. Change the camera’s focal length (without moving the camera angle), and suddenly, the distance between them changes, and one jar looks twice the size of the other. Same jars, completely different visual effect.
- Parallax Effect: Ever been on a train and noticed how trees outside seem to rush by, while distant mountains barely move? That’s the parallax effect: where objects at different distances appear to shift as your perspective changes. In table tennis, this happens with the tiny, fast-flying ball, making what we see on screen more of an optical illusion than reality.
- Angles and Stabilization: Not to mention the limitations of camera angles and stabilization. Broadcast cameras are set up to capture the match, not conduct a CSI-level investigation. We’ll never get the exact perspective of the players and umpires on the court.
Why Cameras Struggle to Capture Table Tennis
Cameras have revolutionized modern life, no doubt. We live in an age of instant replay and armchair refereeing, no doubt. But in table tennis, basically the Formula One of racket sports, accurately capturing a ball traveling at 70 mph with 150 spins per second is a tall order, let alone judging the key serving moments. It’s like guessing someone’s height from their Tinder profile picture: fancy and appealing, but it just doesn’t hold up.
Let’s be honest, under such relentless scrutiny, every player would look guilty at some point. The footage can make it seem like the ball is obstructed, tossed less than 16 cm (about 6 1/3”), or not vertically, even if it’s not bothering in real-time. A ball that appears to fly directly in front of the left eye in the footage, maybe 15” to the left of the body, and higher overhead. As a filmmaker, I’ve seen firsthand how lenses, angles, and stabilization all play tricks on the eye. Maybe it’s my professional bias, but relying on camera footage without considering how it was shot? That’s a gamble I wouldn’t take.
Hawk-Eye to the Rescue
Hawk-Eye in Sports: A Game-Changer
Tired of pixel-by-pixel replay arguments? High-tech solutions like the Hawk-Eye system might just be the answer. While table tennis is still exploring these possibilities, tennis—a sport that has matured significantly in various aspects—has already demonstrated how technology can revolutionize officiating.
At the 2020 US Open, Hawk-Eye Live, a fully electronic line-calling system, replaced line judges in some matches2 after more than a decade of testing at international events. The move was widely praised and welcomed by both players and fans. “Most of the players really liked it. You never have to question one single call,” said Thomas Johansson, former top-10 player and then coach of David Goffin.3 The system, however, wasn’t entirely glitch-free. During the World Team Tennis 2020 season, a match between Jessica Pegula of the Orlando Storm and Bernarda Pera of the Washington Kastles saw the AI initially rule a ball in, only for Hawk-Eye’s replay to confirm it had actually landed out later.4 Even legends like Rafael Nadal and Roger Federer have long expressed reservations, with Nadal questioning its accuracy in key matches.
Despite occasional hiccups, most players support the shift toward AI officiating in tennis, believing the benefits outweigh the flaws. For many, it represents a significant step forward in ensuring fairness and accuracy.
Is Hawk-Eye the Future in Table Tennis?
When it comes to table tennis, the Hawk-Eye system, known as Table Tennis Review (TTR), feels like the ideal umpire we all wish we had at family game night: no tantrums, no bias, and no “Did you see that?” debates.
Although details are limited, many assume the TTR system works similarly to Hawk-Eye in tennis. Utilizing multiple high-speed cameras, it tracks the ball from different angles, then triangulates the data to create a precise 3D model showing its trajectory, speed, spin, bounce points, and more. In theory, it should cut through the confusion and put an end to the usual camera circus.
- The system was first implemented at the ITTF World Tour Grand Finals in 2019.5
- In a 2020 CNT internal match, 15 Hawk-Eye cameras helped Wang Chuqin successfully challenge a call on his serve in the mixed doubles final.
- At the recent Mixed Team World Cup in Chengdu, six TTR challenges were initiated on the final day,6 one of which saved Team Korea from losing a point over an edge ball against Team Hong Kong.
So, why isn’t this tech standard in table tennis yet? Officially, COVID-19 stalled its rollout. Unofficially? Financial concerns? Resistance to change? Who knows. But it seems to be on its way, as the ITTF has endorsed the introduction of TTR at the World Championships Finals in Doha next year.7
Maybe we’ll finally see some consistency that players and fans deserve. Fingers crossed.🤞🏻
The Fine Line Between Strategy and Chaos
Speaking of borderline serves, the blend of artistry, strategy, and a touch of psychological warfare. If regular serves are a handshake, these are a sly wink with a hidden agenda. It’s the one moment where you have complete control of the ball, and a calculated weapon in the mental game where every spin, toss, angle, and placement matters.
Take Ma Lin’s legendary ghost serve, which is short, loaded with heavy underspin, and paired with deceptive follow-up motions designed to confuse opponents. It’s genius, borderline evil, and of course, controversial. But like all elite sports, pushing the boundaries is more about strategy rather than cheating.
Pushing the Boundaries
Across sports, this balance between creativity and enforcement plays out everywhere.
In baseball, catchers are glove-wielding con artists, subtly shifting their mitts to make borderline pitches look like strikes to the umpire. Fielders pull off the occasional hidden-ball trick, pretending to toss the ball back to the pitcher while secretly holding onto it, waiting to tag an unsuspecting runner. Pitchers get in on it too, using feints and subtle movements to throw off baserunners and sneak in surprise pickoff attempts.
In hockey, coaches sometimes pull the goalie earlier than usual or even take a too-many-men penalty during a 5-on-3 just to stop play and reset. Players might cut through the crease, push faceoff timing, or use stick curves right at the legal limit. These tactics toe the line, constantly testing how far the game will let them go. In football, offenses employ deceptive formations to obscure eligible receivers, aiming to confuse defenses. They also manipulate snap timing to disrupt defensive rhythm. Additionally, pushing the ball carrier forward during scrums has become a strategic move, though it skirts the rules against assisting forward progress.
Every sport has its loopholes, and the best players exploit them without breaking the rules. These moments aren’t about deception for the sake of deception. They’re about forcing opponents into mistakes, maximizing every small advantage, and pushing the game forward.
When Strategy Becomes an Art, a Part of the Game
So, what separates these maneuvers from outright cheating? Intent and execution. Rather than playing by the rules, the top athletes and sports teams master them, testing the absolute limits of what’s allowed. Wang Chuqin’s serves are, in fact, an excellent illustration of this sophisticated athletic communication.
The most thrilling moments in sports happen in those razor-thin spaces between what’s expected and what’s possible, in those gray areas, where creativity meets precision, and players redefine what’s possible.
Competition at the highest level goes beyond physical ability. It becomes a dynamic dialogue of adaptation in which athletes constantly read, interpret, and counter each other’s strategies. In table tennis, borderline serves are the spark, a calculated risk that elevates the game into a high-stakes battle of wits and reflexes.
Or, to put it simply, it’s just a part of the game.
If It’s Not Called, It’s Not Illegal
At the heart of table tennis officiating is a system built on clear, commonly agreed-upon rules. These rules are the foundation for fairness, and the role of the umpires is to enforce them as consistently as possible. Umpires are right there on the court, not squinting through some grainy live stream or getting dizzy from slow-motion replays.
The Truth About Table Tennis Officiating
Critics often claim the system is biased or corrupt, but rarely provide evidence to back up their accusations. The numbers tell a different story. I reviewed some stats from major competitions over the past few years, including the World Championships in Durban & Busan, WTT Singapore Smash 2024, and the Paris Olympics. The data consistently shows no systemic bias.
Warnings and penalties for illegal serves are issued regularly, proving that umpires are diligent about enforcing the rules. There is no evidence of favoritism based on language, race, association, gender, or even the type of match—whether singles, doubles, or mixed doubles. Nor is there any sign of double standards within matches. The same rules apply to everyone, making the system the Switzerland of sports officiating.
Of course, no system is perfect. Split-second decisions are part of professional-level play, and occasional mistakes are bound to happen. Players and umpires are humans, not robots with 20/20 hindsight. One wrong or missed call doesn’t mean the entire system is a dumpster fire or anyone’s trying to cheat. It’s more like, “Oops, my bad,” and then everyone moves on.
Yet, despite these flawless, human officiating remains our best option and has proven itself effective time and again. Even with advanced tools like Hawk-Eye in place, human oversight is essential. While precision is critical, interpreting the game’s dynamics and applying context requires the nuanced judgment that only an experienced umpire can offer. The future of officiating isn’t about replacing umpires but enhancing their work with complementary tools.
Why Officiating Needs a Human Touch
This reliance on human judgment isn’t unique to table tennis; it’s a cornerstone of many sports. Take tennis, for example, where human officials bring an irreplaceable layer of unpredictability, emotion, and texture to the game. Tennis player Noah Rubin once said, “I’m usually not a tennis traditionalist, but there’s something about having those line judges dressed up in the back of the court making the calls. There’s definitely something missing” when human line judges are replaced.8 Consider the 2009 US Open semifinal between Serena Williams and Kim Clijsters.9 It’s remembered not just for the tennis but for Serena’s fiery outburst over a foot-fault call. Fueled by human decisions, moments like this become part of tennis lore. Legendary chair umpires like Mohamed Lahyani and Carlos Ramos also enrich the game (perhaps not always in a praised way) with their distinct personalities and memorable interactions. While AI promises flawless calls, it can never replicate the messy, deeply human essence that keeps us glued to the action.
Back to table tennis. Some critics argue that its officiating system is outdated. My inner progressive is shouting, “Yeah! Democratize the system!”
Let’s have instant experts, fans, and players themselves vote on rulings and decisions. Imagine setting up Hawk-Eye over every inch of the court while thousands of livestream viewers pause matches mid-serve to cast votes and debate edge balls in real time via TikTok challenges or Twitter polls. Who wouldn’t want a game decided by the collective wisdom of the internet? Who wouldn’t love a little ITTF/WTT freedom fest? Yeah!
At the End of the Rally…
Judging Wang’s service based on livestream screenshots is like reviewing a chef’s cooking from a heavily filtered Instagram post. Context is missing, nuance is erased, and the full complexity of the moment gets lost. While cameras promise objectivity, they often deliver a fragmented, decontextualized narrative that fails to capture the complex dynamics of high-speed competitive sports. If anything, this debate shows the need for better tech like the TTR system to become standard in table tennis. But technology is just one piece of a more complex puzzle. Sports aren’t just rules and pixels. They’re unpredictable, brilliant, human moments that make us scream at TVs, question life choices, and somehow still love every second of it.
As for me, I’m not here to play the role of a neutral observer or an all-seeing guru. As a table tennis newbie, I’m diving into the sport like a kid at an all-you-can-eat dessert bar—curious and hungry to form my own opinions through personal experience and way of thinking, rather than simply echoing established opinions or letting others control the narrative. After all, every established “truth” in sports started as someone’s wild idea, and every now-legendary technique probably had critics throwing a fit at first. So, yeah, being a rookie? It’s a gift. While everyone else is arguing over screenshots, I’m just here enjoying the ride and figuring things out for myself, without anyone else’s “education” or conversation dominance.
