Mike Sexton had a gift for names. During the 2004 WPT Ladies’ Night, a televised invitational on the World Poker Tour, he gave a French-Canadian player with a relentless raising style the name “No Mercy.” Isabelle Mercier won the event and its $25,000 first prize.
The nickname outlived the broadcast by two decades.
Sexton, the voice of the WPT from its first season and a Poker Hall of Fame inductee in 2009, named a lot of players over the years. Few of the names stuck the way this one did. Part of the reason was the pun on her surname. The rest was that the WPT showed hole cards, so viewers could judge the style for themselves.
It was a good fit because the aggression was real, and because nothing in her background suggested it. Mercier had arrived at the table by way of a law degree and a job running a card room.
From Victoriaville to commercial law
Mercier was born on August 5, 1975, in Victoriaville, Quebec. She took an undergraduate degree in law at the Université de Montréal, then moved to Paris, where she completed a master’s degree while working. For a short time she practiced commercial law.
The legal career did not last. Mercier found poker in Paris and moved to the other side of the industry first, becoming poker room manager at the Aviation Club de France on the Champs-Élysées. The club was one of the most prestigious card rooms in Europe in that period, a place where serious cash games ran and where the European poker scene of the early 2000s gathered. Her work there earned her two nominations for Staff Person of the Year.
Running a poker room is a different education from playing in one. A manager sees how every regular plays, which games stay alive and which collapse, and how money moves around a table over months. If you have ever tried to keep a home game going, you know some of it already: the game survives on the social side as much as on the cards (more on that in the social aspect of poker).
The first results
Mercier started to play tournaments seriously while still close to the Aviation Club scene. In 2002 she finished second at the Masters Classic of Poker in Amsterdam, then one of the established stops on the European calendar, for $53,499.
The 2004 Ladies’ Night win followed, and with it came television. The World Poker Tour was at the height of its first wave of popularity, and a lawyer-turned-card-room-manager with a fast, fearless style was exactly the kind of character the broadcasts wanted. In 2006 she made the final table at the European Poker Tour stop in Deauville, finishing seventh, one of her best results on the EPT.
What “aggression” meant at her table
The label “queen of aggression” can sound like a cliché, but in the mid-2000s it described something specific. Many live players of that era, especially in Europe, played tight: they waited for strong hands and let others make the mistakes. Mercier did the opposite. She raised often, re-raised light and was willing to put opponents to a decision for their tournament life.
That approach pays most against cautious opponents, who fold too often when faced with pressure. It costs most against players who call wide or come back over the top. Mercier’s results and her television reputation came from a period when the first type of opponent was common at live tables. You will recognize the idea in modern strategy, where solvers recommend far more aggression in many spots than the old tight-player habits ever allowed.
Ambassador, author, teacher
Through most of the late 2000s and 2010s Mercier was one of the familiar faces of PokerStars, representing the site as an ambassador at events around the world. In 2008 she published an autobiography, Profession: bluffeuse, and she also released an instructional DVD and appeared in the documentary That’s Poker.
She used the profile for charity as well. In 2009 she won the Ante Up for Africa charity tournament, the event founded by Annie Duke and actor Don Cheadle that ran alongside the WSOP in Las Vegas and raised money for causes in Africa.
In 2017 she left PokerStars and joined CoinPoker, a cryptocurrency-based poker site. The move followed a broader pattern in the late 2010s, when several established names took ambassador roles with new operators.
Open Face Chinese and the later years
One of Mercier’s more unusual titles came in 2015, when she won the inaugural World Championship of Open Face Chinese Poker in Prague. Open Face Chinese is a different game from hold’em: players set thirteen cards into three rows, and points come from beating each opponent row by row and from royalties for strong hands. It became a fashionable side game among professionals in the early 2010s, and Mercier took it up while it was still new on the tournament circuit. If you know pineapple poker, you have met one of its relatives.
By 2015 her live tournament earnings had passed $1.2 million. That figure is modest next to the high roller players of the 2020s, but it understates her place in the game. Mercier was one of the first women to become a recognizable professional on European and North American television, and one of the few to come to poker from management of a major card room. The Prague title came eleven years after the Ladies’ Night win and thirteen after Amsterdam, in a game that was not on the tournament circuit at all when she started.
