Chess's First Computer Cheat Unmasked: The 33-Year Mystery of 'John von Neumann'
For 33 years, nobody knew who he was.
In July 1993, an unrated player walked into the World Open in Philadelphia and registered under the name "John von Neumann." He wore shoulder-length dreadlocks, headphones, and a confident expression. None of it was real.
He beat a FIDE master. He drew Icelandic grandmaster Helgi Olafsson. Then spectators heard something buzzing in his pocket, tournament officials started asking questions, and the mystery man disappeared.
Now, thanks to journalist Kit Chellel's new book Lucky Devils and a feature in Wired published on April 14, we finally know who was behind chess's first documented case of computer-assisted cheating.
The Gamblers
The man in the dreadlocks was John Wayne (no relation to the actor), a charismatic ex-soldier and professional gambler from Los Angeles. Wayne was the front man. The brains behind the operation was Rob Reitzen, a tech-savvy engineer who specialized in building wearable gambling devices.
The two met through chess and arm-wrestling challenges. They belonged to a crew of professional gamblers that included MIT-trained programmers and mathematicians. Their usual targets were casinos. The 1993 World Open was something different: a side project, or as Reitzen later put it, done "for shits and giggles."
The Setup
The technology was crude by today's standards but remarkable for 1993. Wayne entered the tournament wearing:
- A wig of fake dreadlocks, secured with headphones to keep it in place
- A modified blackjack processor adapted for chess
- Toe switches inside his shoes to transmit moves
- A vibrating device hidden in his clothing to receive instructions
While Wayne sat at the board, Reitzen operated from their hotel room, monitoring the games on a computer screen and running custom chess software. Wayne would input his opponent's moves using the toe switches. Reitzen would calculate the best response and send it back through the vibrating device.
The system had problems. It malfunctioned repeatedly, forcing Wayne to play several games on his own - resulting in predictable losses for an unrated player. But when the system worked, it worked well enough to fool a grandmaster.
"I Was Sure I Was Playing a Complete Patzer"
Grandmaster Helgi Olafsson's reaction tells you everything about how suspicious the games looked. After their draw, Olafsson recalled: "I was sure I was playing a complete patzer... he had no idea about the game." The moves didn't match the player making them. Olafsson sensed it, but in 1993, the idea of real-time computer assistance was barely conceivable.
Other players and spectators noticed too. The buzzing sounds drew attention. When tournament director Bill Goichberg confronted "von Neumann" about the irregularities, the player claimed his wife was having a baby and left. When he returned later, officials demanded he play under observation to prove he wasn't receiving outside help. Wayne refused, accused them of racism, and left for good.
The Aftermath
Inside Chess magazine broke the story weeks later under the headline "The Von Neumann Affair Rocks the World Open." The publication correctly theorized that computer assistance was involved, but incorrectly assumed the instructions came through headphones. The actual method - toe switches and vibrations - was more creative than anyone guessed.
Nobody ever identified the players. The fake name was the only lead, and it went cold.
Wayne died of cancer in 2018, taking his side of the story with him. Reitzen went on to far bigger things in the gambling world. He developed early superhuman poker bots and was eventually inducted into the Blackjack Hall of Fame. It took Kit Chellel's investigation for Lucky Devils to connect the dots and confirm what chess officials had suspected for three decades.
Why This Matters Now
In 1993, the idea of a chess computer strong enough to help a human cheat was barely taken seriously. Inside Chess warned prophetically at the time: "If computers become strong enough to be of genuine assistance to top players, then watch out!"
Four years later, Deep Blue beat Kasparov. Twenty-nine years later, Hans Niemann was accused of cheating in the most explosive scandal in modern chess history. Today, any smartphone running Stockfish can demolish the best human player alive.
The Von Neumann affair was a preview of everything that followed. The methods got smaller, the engines got stronger, and the problem got harder to solve. What Reitzen and Wayne cobbled together with modified blackjack processors and toe switches in 1993 can now be replicated with a phone in your pocket and an earpiece. FIDE, Chess.com, and tournament organizers are still fighting the same battle, just with better tools on both sides.
If you watched Netflix's Untold: Chess Mates and thought the cheating debate started with Carlsen and Niemann, it didn't. It started with a man in a fake wig, a buzzing pocket, and a hotel room in Philadelphia.
