Mansour Matloubi is an Iranian-British poker player who made history on 17 May 1990 when he won the World Series of Poker Main Event for $835,000, becoming the first non-American ever to claim the world championship title. Playing under the Welsh flag from his adopted home of Cardiff, Matloubi — largely unknown to the poker world before that week — defeated a field of 194 players that included Stu Ungar, the greatest player of the era, to enter the poker history books permanently.

Biography & Poker Background
Mansour Matloubi was born in Iran in 1952 and moved to Cardiff, Wales in 1972, where he obtained citizenship and built a life before discovering poker. He travelled to the 1990 WSOP with a group of fellow British players — largely as a relative unknown in the context of the Las Vegas poker world. What unfolded over the following days changed British poker history.
The 1990 Main Event is notable on multiple counts. Among those he outlasted was Stu Ungar — widely regarded as the greatest Hold’em player of all time — who had accumulated a dominant chip lead before a medical emergency (an overdose in his hotel room) left him blinded out during play, eventually finishing ninth. Matloubi himself had to survive a harrowing heads-up battle against Hans “Tuna” Lund, during which he went from two outs to winning when a ten fell on the river in the most critical hand of the match. Pocket sixes then ended the contest.
His background favoured Pot Limit Omaha over No-Limit Hold’em — a discipline in which very few players of that era were truly proficient. His ability to win the world’s biggest No-Limit event from that standing underlines a broader understanding of poker fundamentals.
In the aftermath of his 1990 win, Matloubi was famously involved in a cash game against Ungar, where Ungar called him down with ten-high and won. Matloubi reportedly refused to play Ungar again after that encounter. He continued competing actively through the 1990s, making the Main Event final table again in 1993, before largely retreating from the spotlight. He has since cashed in events as recently as 2025, remaining one of poker’s great living history figures.
Legacy
Matloubi’s 1990 victory broke a barrier that had stood for two decades: every previous WSOP Main Event champion had been American. He opened the door that would eventually see champions from across the world, and his win is cited in almost every account of poker’s globalisation. He played under the Welsh flag, making him part of Welsh poker history as much as British history — though his career was built largely from London, where he eventually settled.
