Jonathan Tamayo won the 2024 World Series of Poker main event and the $10 million first prize, but his victory was immediately overshadowed by allegations that he had exploited a loophole in the tournament’s rule book. The controversy centered on his rail team using poker solvers in real time, a practice that was not explicitly banned by the written rules for the event. The 2024 WSOP main event was the largest in history, with over 10,000 players competing. Tamayo, who finished 21st in the 2009 main event for a six-figure cash, had been a relatively under-the-radar professional for 15 years.
When the 2024 rule book was released, his team reportedly noticed that the language around real-time solver use was vague, with no explicit ban on rail members using the software away from the table. During the tournament, Tamayo was observed repeatedly stepping away from the table between hands to confer with his rail team. His coaches were seen huddled around a laptop, and Tamayo reportedly returned to his seat with remarkable certainty in his decision-making. His play was characterized by near-perfect folds and calls, drawing suspicion from commentators and fellow professionals.
The situation escalated when a spectator photographed the rail team’s laptop, with the screen displaying a poker solver program. The image quickly spread across social media and poker forums, prompting widespread debate and calls for an investigation. Despite the mounting pressure, no written rule had been broken at that point, as the tournament’s official announcement only asked players not to use solvers “at the table or in the tournament area. ”
At the final table on July 15, Tamayo made a decision that became a focal point of the controversy.
In heads-up play, he folded pocket queens, a move widely considered almost unheard of in that situation. Shortly afterward, a solver image surfaced that reportedly confirmed the fold was mathematically optimal, leading many to question how Tamayo knew to make the play. Tamayo went on to win the tournament, securing the championship and the $10 million prize. During the ensuing celebration, a video clip appeared to show a small white object being passed between Tamayo and his rail member Joe McKeehen during a long embrace.
Speculation quickly spread that the object could have been an earpiece or other communication device, though this was never confirmed. The World Series of Poker announced a formal investigation within 48 hours of the victory, promising to review available footage and evidence. However, the organization faced a significant obstacle: the 2024 rule book did not explicitly prohibit rail members from using solvers or relaying information to players. The only relevant enforcement was a vague announcement over the tournament speakers requesting that solvers not be used in the tournament area.
Prominent players, including Doug Polk, Daniel Negreanu, and Alan Keating, demanded stricter rules and some called for Tamayo to be stripped of his title. Others defended Tamayo, arguing that he had followed the rules as they were written and that rail assistance has long been a part of live poker. Dominic Nitsche, a rail member for Tamayo and a respected professional in his own right, escalated the controversy by posting a taunting message on Twitter: “The best part of having a piece of the WSOP main event winner is watching people cry about a laptop. ”
Despite the backlash, the WSOP concluded its investigation without taking action against Tamayo.
His $10 million prize remained intact, his bracelet was not stripped, and the official records list him as the 2024 WSOP main event champion. The broader question of whether solvers and real-time assistance would force the WSOP to tighten its rules for future tournaments remained unresolved.
