Schedule of Events
Rules for Brazillian
Each team consists of four players. Before each match, a team must submit an order for its players. To begin a match, each team sends the first player in their line-up to the table to play one point. Whoever wins the point stays on the table and earns a point for the team. Whoever loses the point must leave the table, and the next player in line on his/her team will play the next point. The challenging player always serves. The process continues (once all players on the team have lost a point, the first player goes back onto the table again) until a team reaches 33 points (no deuce).
Thank you Taste of Hunan, a local restaurant that specializes in traditional Hunan cuisine, for sponsoring this tournament.

- Registration fees. In addition to the event fees, we will charge a $10 tournament registration fee.
- Non-Sanctioned. This tournament is not USATT sanctioned. Everyone is welcome to play. We will not charge a ratings fee or USATT membership fee, and the results do not affect your USATT rating.
- Eligibility. This tournament is open to all players. You can play and advance whether you have a rating or not, and may self report your rating. However, as a general guideline we will be using the official ratings list as of August 1, 2021 to determine eligibility cutoffs for rating events.
- Self-reporting Ratings If you do not yet have a USATT rating or feel that you are severely overrated due to the long layoff during the pandemic or other reasons, you may also self-report your estimated rating (be honest, please) using this Google form. Provided that your self-reported rating is within reason, you will be permitted to advance from all the events you enter in. Please note that you still need to register for the tournament first on Omnipong before we can adjust your rating.
- Match length. The Open Singles semi-finals and finals will be four out of seven. All other matches will be three out of fives.
- Max Entries. In order for the event to run on time, we will be placing a maximum number of entries on each event. The number of max entries are posted on Omnipong.
- Payments. As a result of our capon entries , in order for your spot in our tournament to be guaranteed, entries must be paid in full beforehand either online on Omnipong (preferred) or in person at After School Learning Tree.
- Waitlist. If an event has already received its maximum number of entries and you would like to be placed on the waitlist, please fill out this form.
- Round robins. Round robins will be groups of four.
- Seeded Players. In order to ensure that the event runs on time and that all round robins have four people, up to four top-rated players may be seeded directly into the knock-out round in each event. Players who do not wish to be seeded directly into the knock-out round may opt out.
- Finish Time. All events will finish on the same day they start. To ensure that the Under 2000 finishes on time on Saturday night, we will allocate two tables to each round robin.
- Contact. Please call or text (619) 253-1093 or email email@example.com to reach a tournament representative.
Request to Change Your Draw
Our goal is that you let to play the players that you want to play at our tournament. If for whatever reason you would prefer a different draw, please fill out this Google form. We will do our best to accommodate your request as soon as possible.
While it is optional for you to provide a reason for your request, and we will do our best to grant all requests, if several requests conflict we will grant higher priority to requests with a good reason. Several possible reasons for wanting a new draw include (but are not limited to):
- There is one person who you normally play with all the time (so you do not want to play each other at the tournament) who you are slated to play in the round robin or an early single-elimination round
- There is a certain player, or a certain style of play, that you really want to play
- You have been seeded out of the round robin directly into the knockout stage but would prefer to play a round robin
- You are slated to play someone in the group or first round multiple times in the tournament
- You believe your side of the draw if significantly harder than the other side
Food on Saturday
We will be selling lunchboxes from Taste of Hunan starting around noontime on Saturday. An example lunch box is shown in the image below. We have specifically asked the requested the restaurant to add less oil so that the meals are easily digestible and you will be ready to play soon after eating it. We offer three variations: beef, chicken, and vegetarian.
We will be selling each lunchbox for their normal price of $12.50 at the tournament. However, if you pre-order your lunchbox either on the “goodies” section in Omnipong (preferred) or using this Google form by August 11, you can get a special deal for $10. Feel free to order lunchboxes for yourself, parents, children, friends, spouses, and romantic love interests.
If you like the lunchboxes, please consider eating at the restaurant, where there is a much more extensive menu, for a full meal later.
Update: Due to limited bandwidth from the tournament directors, we will not be using Ratings Central this time around.
We will be experimenting with Ratings Central, a rating system widely used in Europe and Australia. Based on Bayesian statistics, Ratings Central accounts for the inherent uncertainty in assessing a player’s rating. As a result, it is more accurate and provides more information than the more vanilla ELO-based rating systems like the one used by USATT.
How does this affect you as a player?
It does not! Feel free to completely ignore this section! We do not charge a ratings fee, your USATT rating will not be impacted, and nobody in the US is going to ask you about your Ratings Central rating. We simply wanted to let you know that your results will be input into the system. However, if you are interested, we expect ratings to be posted onto the Ratings Central website shortly after the tournament. Please note that ratings may be volatile after the first tournament but should become more accurate after you play more tournaments in San Diego.
Are you scared in your joints that you will be marginalized under this new system? Read more about Bayesian statistics and how the Ratings Central system works so that you don’t feel like an imposterior!
We hope to make our tournament as player-friendly an experience as possible. If you have any other questions or requests for the tournament staff, let us know using this Google form, and we will see whether we can accommodate you.
The tournament is free to watch in person, and all our welcome. While spectators are welcome to watch all events, we would like to hilight our headliner event.

- Once someone else has made a prediction, you cannot make the same exact prediction. You can view existing predictions here.
- You can submit a prediction up until just before the Open Singles Finals starts.
- You can make a prediction either at the front desk on the day of the tournament or using this Google Form. Please note that you must watch the Open Singles Finals in person to enter the contest.
- Whoever has the closest prediction wins a pack of three Nittaku Premium balls.
