What Is the Unibet DeepStack Open?
The Unibet DeepStack Open is a live poker circuit sponsored by Unibet. The circuit is run under the direction of Alexandre Henry, in partnership with Texapoker, and features around a dozen stops in 2026.
What makes UDSO different is its focus on value and structure. Main Events are affordable at €550, but players get deep stacks and long levels, so there’s plenty of room to play poker rather than shove or fold. Each festival also includes a wide range of side events, from €120 turbos to €1,100 High Rollers.
Most stops are in France, but the tour also visits Italy, Romania, Estonia and Morocco.
UDSO vs Unibet Open: The Unibet Open (UO) is Unibet’s original flagship live tour, while UDSO is its more affordable DeepStack circuit. They are related but separate brands. In 2026, the two were combined at selected stops such as Paris and Marrakech.
