Thomas Clack had already been banned for using a solver during a tournament
Grosvenor Poker has withdrawn a sponsorship package from UK professional Thomas Clack following an online cheating violation. Clack, a well-known British player with more than $1 million in live tournament earnings, was removed from the deal after being banned on the iPoker network for breaching its rules.
Clack earned the sponsorship by winning Grosvenor Poker’s 2025 National Poker League, a promotion that awarded a £40,000 (US$48,000) package. His rise over the past year included the biggest cash of his career, finishing second in the 2025 Goliath tournament for £217,500 (US$259,000), which firmly placed him among the UK’s most visible poker players.
The issue surfaced after iPoker determined Clack had a solver open while actively playing online. Solvers are considered prohibited software during real-money games, regardless of intent. The ban from iPoker also triggered a ban from Grosvenor’s online platform.
Clack addressed the situation publicly through Instagram Stories, admitting he had the solver running but denying real-time use. He said he was reviewing a previously played hand to study his decisions, calling it a poor judgment rather than an attempt to gain an edge. He described the situation as a costly mistake that ended what had been a strong year.
Grosvenor Poker later confirmed that the sponsorship could not be honored. The operator explained it was notified of Clack’s suspension after the league ended, and that eligibility rules require sponsored players to be permitted on both live and online platforms. With the online ban in place, Clack no longer met the criteria.
Despite losing the sponsorship, Clack remains eligible to play in live events at Grosvenor venues. He closed his statement by thanking supporters and acknowledging potential criticism, while maintaining that those familiar with him understand he did not intentionally cheat.
