WPN Online Super Series XL: $50M GTD Sept. 7 – 30

The Winning Poker Network, including America’s Cardroom and Black Chip Poker, is back at it again with more huge guaranteed prize money. The Online Super Series (OSS) XL returns, and this time it features $50 million in guaranteed prizes spread over more than 700 series events. It runs from Sunday, Sept. 7 through Tuesday, Sept. 30.

OSS Info

Despite the official OSS schedule showing numbered events up to only #371, the series actually features more than 700 action-packed tournaments. The reason behind this seeming discrepancy lies in the separation of some of the events into high, medium, and low versions. A few even have a fourth, micro edition.

For instance, OSSXL #137H ($100,000 GTD Mystery Bounty) costs $109 to enter while OSSXL #137M ($50,000 GTD Mystery Bounty) and OSSXL #137L ($10,000 GTD Mystery Bounty), which occur on the same day and begin at the same time, are priced at $33 and $8.80 respectively. Meanwhile, #137Micro ($2,000 GTD Mystery Bounty) costs just $2.20 to enter.

Therefore, there are far more series events than you might think by looking at the numbers attached to these tournaments.

Buyins start at a low-roller-friendly $0.55. More expensive events beckon for those who want a bigger thrill up to $2,650. Thus, the OSS XL caters to those of all bankroll levels.

A Diverse Schedule and Wide Range of Games

In addition to having a broad menu of buyin levels to choose from, the OSS XL offers several varieties of poker. Though most of the tourneys are for the ever-present NL Hold'em, there are a reasonable number of PLO and PLO8 contests too as well as a few 5 Card PLO and 5 Card PLO/8 games. Even Seven Card Stud Hi-Lo is represented in the schedule although other limit games, like Hold’em, are absent.

Occasional turbo and 6-max events provide a break from the routine as do progressive knockouts. Mystery bounties and hypers are a couple of the other wrinkles you'll see in the series.

With the number of tournaments on the OSS roster XL, no single individual can enter them all. Therefore, you will have to look carefully in the poker lobby and select those that interest you the most. Nevertheless, there are a few major events that you may wish to keep your eye on.

Main Events

This OSS has three separate main events, which are a $215 buyin with $750,000 GTD (OSSXL #3), a $1,050 buyin with $1,500,000 guaranteed (OSSXL #2), and a $2,650 buyin with $2,000,000 guaranteed (OSSXL #1).

Each of the three regular Main Events follows the same schedule. They both have a starting day on Sunday, Sept. 21 at 11:05 a.m. ET and a second starting day at the same time on Sunday, Sept. 29. Then the survivors from these days of play gather at 1:30 p.m. ET on Monday, Sept. 29 to play Day 2.

For the smallest Main ($215 buyin, $750K GTD), the tournament is over after the second day of play. However, for the larger ones, Day 2 plays down to the final table. Then the remaining nine individuals reconvene the following day at 2:05 p.m. ET until only one remains.

Multi-Flight Events

There are four multi-flight mystery bounty events in this installment of the OSS XL. This means that there are numerous Day 1 flights, which are combined to play to a conclusion on Day 2. Also on Day 2, randomized bounties are awarded for eliminating opponents.

There are two of these tournaments with a $109 buyin and $500,000 guaranteed. The first one (OSSXL #4) has Day 1 flights starting Sept. 7 and continuing through Sept. 21. The second day occurs on Sunday, Sept. 21 at 5:05 p.m. The second multi-flight mystery bounty (OSSXL #6) runs Day 1s from Sept. 21 to 29 with the second day of play taking place on Monday, Sept. 29 at 2:05 p.m.

There are also two smaller multi-flight MBs to enjoy. OSSXL #7 provides $200,000 guaranteed on a buyin of $33. OSSXL #8 guarantees $100,000 and has a buyin of $5.50. Day 1s for both of them commence Aug. 31 and continue through Sept. 28. Then Day 2 begins on Sunday, Sept. 28 at 2:05 p.m.

Players can join multiple Day 1s for the Mystery Bounty events, and the chip stacks from each of them will combine to form the Day 2 starting stack.

Multi-Flight Non-Bounty

There's a big multi-flight event (OSSXL #5) on the roster with a $630 buyin and an incredible $1.5 million guaranteed. This one is a normal tournament, though, with no bounties. You can enter any Day 1 from Sept. 7 to Sept. 29. The second day takes place Monday, Sept. 29 at 2:05 p.m. ET with the final table running the following day.

For this tournament, you can participate in multiple Day 1s. However, if you're playing in one, you cannot register in a second one, and once you qualify for Day 2, you cannot enter any more Day 1s.

Survivor Flips

In addition, there's a special Survivor Flips Event that costs $130 to enter and has a $150,000 guaranteed prize pool. Phase 1 flips run together with Steps from Sept. 17 to 21.

Phase 2 begins on Sunday, Sept. 21 at 3:05 p.m. This portion of the event plays out like a normal tournament.

Leaderboard Prizes Await

As it sometimes does, the Winning Poker Network is providing a leaderboard for the OSS series with $65,000 in added prizes. Actually, there are three separate leaderboards, catering to different levels of buyins: Low (under $15), Mid ($16.50 - $88), and High ($104.50 and over). Points toward the leaderboards are generated for in-the-money finishes only and are awarded based on the square root of the prize pool divided by the square root of a player's finishing position.

The Low leaderboard will pay out as follows:

• 1st: $4,000
• 2nd: $2,000
• 3rd: $1,500
• 4th: $1,000
• 5th: $500
• 6th: $251 in Tournament Tickets
• 7th: $160 in Tournament Tickets
• 8th: $86 in Tournament Tickets

The Medium Leaderboard meanwhile will award the following:

• 1st: $7,500
• 2nd: $4,000
• 3rd: $3,000
• 4th: $1,500

• 10th: $648 in Tournament Tickets

Satellites Beckon

Although many of the MTTs on the OSS lineup are already geared toward those on smaller bankrolls, there's another way to participate in some of the events even if funds are low. A broad array of satellites exists that let you attempt to win your seat for less than the sticker price. These qualifying tournaments are priced at just a few bucks, and actually, there are even freeroll satellites that cost nothing to enter.
