Pick Your Pro: Exciting New Race for OSS XL

For the first time in OSS XL history, ACR Poker decided to try an unusual experiment. The team took 10 of their Pros and split them into pairs who compete against each other in the series’ tournaments:

• Chris Moneymaker vs. Rob Kuhn: $11 – $109 OSS XL events
• Jon Pardy vs. Drew Gonzalez: $11 – $109 OSS XL events
• Ana Marquez vs. Monika Zukowicz: $11 – $109 OSS XL events
• Jeff Boski vs. Michael Loncar: $11 – $109 OSS XL events
• Chris Moorman vs. Alex Foxen: $11 – $109 OSS XL events

Each player must play between 30 and 60 events of eligible buy-ins — anything beyond that will not be taken into account. Their goal is to win more prizes than their opponent in the pair.

What’s in it for regular players? Well, until 11:59 pm ET on September 5th, 2026, we can choose our champion in each pair by buying into his specific $33 Pick Your Pro $5,000 Gtd tournament.

If your champion loses to their opponent at the end of the series, his or her tournament will not be held, and the buy-ins paid for it will go into the winner’s tournament prize pool, minus the rake.

Winners’ tournaments start at 04:00 p.m. ET on October 4th, 2026.

All OSSXL: Pick Your Pro tournaments have the same structure:

• Starting stack — 100,000 chips (100 bb)
• No late registration
• Blind level — 6 minutes

They can be found in the lobby by name.

Don’t try to register for tournaments of both players of the same pair or you’ll be disqualified without a refund of your buy-ins and the opportunity to play in the winner’s tournament!

Classic OSS XL Leaderboard: $60,000 for 26 Players

Traditionally, the Online Super Series is accompanied by three leaderboards, with points calculated by the same formula:

Square root of the prize pool / square root of the finishing position

Only OSS XL series tournaments count, and points are awarded only for reaching the ITM of events of the corresponding buy-ins:

• Low — under $15
• Medium — from $16.50 to $88
• High — $104.50 and more

Prizes based on the results of the series in each leaderboard will be awarded to 8 to 10 people:
