NAOBC Premier Knockout

The NAOBC Premier Knockout is open to all ACBL members in good standing. (Join the ACBL or renew your membership here.) The first three or four matches (depending on attendance) will be held Thursday, July 23–Sunday, July 26, and the last three or four matches (depending on attendance) will be held Thursday, July 30–Sunday, August 2. Each match is 56 boards and will be played on Bridge Base Online.

NAOBC Premier Pairs

The NAOBC Premier Pairs is open only to players who entered the NAOBC Premier Knockout (and are not playing the concurrent semifinal / final matches) or members in good standing who qualify for the Platinum Pairs (that is, players who meet one of three criteria: 1. 50 Platinum points in the three previous calendar years; 2. 200 Platinum points lifetime; 3. Grand Life Master or Platinum Life Master ranking). This is a four-session pair event on Saturday, August 1 and Sunday, August 2, with 24 boards played per session. Only the top 50% of the Saturday field qualifies to play in the Sunday final.

$100 / pair / event. Players who qualify for the final play free. NABC Junior discounts apply.


Pre-registration for the NAOBC Premier Knockout is mandatory and is limited to the first 256 teams. Entries will be sold on BridgeWinners.com starting Friday, July 10. Sales close at midnight Eastern time, Monday, July 20.

Entries for the NAOBC Premier Pairs will be sold on Bridge Base Online, and pre-registration is not needed – entries go on sale two hours before game time.


Conditions of Contest, NAOBC Knockout Teams

All rounds will be played on Bridge Base Online. Full day knockout matches will be 56 boards in length, played in four fourteen-board quarters. Half day knockout matches (possible in the first round as part of a four-way match) will be 28 boards in length, held in two fourteen-board halves. The time allotted to each fourteen-board segment will be one hour and forty minutes.

Entries for this event will be sold on BridgeWinners.com and will be limited to the first 256 teams that enter. All players must be ACBL Members in good standing. The entry deadline is midnight Eastern time, Monday, July 20. After this deadline and before noon Eastern, Wednesday, July 22, an entry may be accepted if, in ACBL Management’s opinion, it would improve the format of the event.

Unless otherwise specified in this document, the Conditions of Contest of this event are the same as those of the Spingold Knockout Teams. The Director in Charge will decide, and have final say on any issue not addressed in these Conditions of Contest or the Spingold Conditions of Contest.

All entered pairs must have a completed ACBL Convention Card submitted in pdf or similar format by Tuesday, July 21. These Convention Cards, as well as any supplemental information such as WBF convention cards, USBF system summary forms, or similar document provided, will be made publicly available on the ACBL website. Any team without ACBL Convention Cards submitted by Tuesday, July 21, will lose one segment of seating rights in each of their first two matches. Any team without ACBL Convention Cards submitted by 9:00AM EDT Thursday, July 23, will not be permitted to play in the event. Players are also expected to post convention cards within the Bridge Base Online environment.

Bracketing will be done as in the Spingold unless there are 33/34/65/66/129/130 entrants. In those cases one or two four-way matches with three survivors will be played the day before the Round of 32/32/64/64/128/128 to achieve a number of surviving teams equal to that power of two.

Seeding will be done subjectively by the ACBL Seeding Committee, using data from the ACBL Seeding Program and research as time permits. Decisions by this body will be final.

If 128 teams or fewer enter the event, teams in head-to-head matches will be given the option to play their Round of 128 match on Thursday, July 23, Friday, July 24, or in two halves, one on each of those two days. If the teams cannot come to agreement, the match will be held in its entirety on Friday, July 24.

Play in head-to-head matches in the Rounds of 256 through 32 will be held at teams’ agreement at either 10:00 and 3:00 EDT, 1:00 and 6:00 EDT, or 4:00 and 9:00 EDT. If the teams cannot come to agreement, the match will be held at 1:00 and 6:00 EDT. These times must be submitted to the Director in Charge at least one hour before the teams begin play. Teams in four-way matches will play their matches at 1:00 and, if necessary, 6:00 EDT. Play in the Rounds of 16 and later will be at 1:00 and 6:00 EDT.

Team lineup and seating information for the team without seating rights must be submitted at least 30 minutes before a segment. This information will be transmitted to the team with seating rights, who will then transmit their lineup in time for an ACBL representative to set up the segment online.

Conditions of Contest, NAOBC Premier Pairs:

All sessions will be played on Bridge Base Online. The NAOBC Premier Pairs will be held in four sessions, two each on Saturday, August 1 and Sunday, August 2, will be open only to players who entered the NAOBC Knockout (and are not playing in the Knockout Semifinal) or ACBL Members in good standing who are qualified to play in the Platinum Pairs – that is, meeting one of these three criteria:

  1. 50 Platinum points in the previous three calendar years
  2. 200 Platinum points lifetime
  3. Grand Life Master or Platinum Life Master ranking

Only the top 50% of the field after the two Qualifying sessions will be invited to play the two session Final the next day. Entries for this event will be sold on Bridge Base Online, and the deadline for entry is the start of the event. Registration will open two hours before game time. This pair event will not be stratified. Sessions will begin at 1:00pm and 6:00pm Eastern time and will be 24 boards in length.

Appendix O: Online Play in the 2020 Summer North American Online Bridge Championship KO

  1. Cheating: Cheating online is a serious offense, subject to the same penalties as cheating in live play. It is illegal to communicate with your partner during a hand via any means other than chat to the full table, to communicate with a kibitzer during the game, to play using an account that is not yours, to gain advanced knowledge of a deal, or to play in one event using multiple accounts.

    Any accusation of cheating must be made privately to the director of the event, to the ACBL recorder, or to a reporting mechanism provided by the online platform.

  2. Alerts: Alerts (including announcements) are made by the player making the call. An alerted call should be accompanied by an explanation. Stating the common or popular name of the convention is not sufficient. You are encouraged to explain calls even if those calls do not require alerts. Any call that would be alerted after the auction in live bridge should be alerted at the time of the call.
  3. Any contestant may request information concerning an opponent’s methods. Such inquiries should be directed to the player who made the call and must be asked in a private chat. Replies to these inquiries must likewise be given in a private chat. When playing with a Zoom (or the equivalent) screenmate follow up questions are permitted regardless of which player made the call or play.
  4. Tempo: In general, bids and plays within 10 seconds are considered to be in tempo.
  5. Claims and concessions: If you reject an opponent’s claim or concession, and continue play, the result of the board will stand as played. Instead of rejecting the claim or concession, you may call the Director for an adjudication of the result.
  6. Unfinished hands: A hand that is partially completed when time expires is adjudicated as equitably as possible to both sides. Any doubtful point will be resolved against the partnership that is considered most responsible for not finishing in time.
  7. Undos: Unintended calls or plays will be rectified under the Laws of Duplicate Bridge. A contestant who makes an unintended call or play should summon the Director immediately. As in live play, undos are permitted only upon instruction of the Director.
  8. Table Chat: All chat is authorized information for opponents and unauthorized information for partner.
  9. Convention Cards: Partnerships are encouraged to have a convention card that includes the players’ real names. Pairs without cards will be at a disadvantage in misinformation rulings. If the system loads a default card for pairs without a convention card, then you should not assume that your opponents are playing those methods.
  10. Information Available in the Software: All information provided by the software is authorized. For example, if the software has a button to view your convention card during the hand, then it is legal to use that button to view your own card. Consulting a written defense is allowed in any situation where it would be allowed in face to face bridge. Using any other aid to memory is illegal. Illegal aids include consulting a system notes document or tracking the cards played on paper.
  11. Irregularities: The Director must be summoned electronically for any irregularity. Once the Director has been summoned, all play and bidding shall cease until the Director authorizes its continuation.


During all team matches, players will be required to have an ongoing video or audio chat session with their screenmate (North and East are screenmates; South and West are screenmates). This chat can be done in a software of the players’ choice, or by telephone call; if none can be agreed, the default choice is Zoom. Alerts will be given in the online playing environment in order to have a record of these explanations. (Note: Online Alerts, including when playing in a “screenmate environment”, are currently under discussion by the ACBL Laws Commission, and a clarification from them may be forthcoming.)

Players are strongly urged to set up over-the-shoulder cameras external to their computer, as an added security step. ACBL will provide vendor information. These cameras will be used in future events for security purposes as well.

Kibitzing will not be allowed other than by tournament staff. All matches of the Quarterfinals and later, as well as a number of matches in earlier rounds, will be on Delayed Vugraph.

Every hand from each match of the team event will be viewed (at the time of play or at a later time) by at least two ACBL employees who are very experienced bridge players. If any of these officials “flag” a hand for investigation, it will be sent to a players’ committee who will further investigate for unauthorized communication. Furthermore, any hand that a player in the team event submits for further investigation will be sent to the players’ committee. Any hand that a player in the pair event submits for further investigation will go to the ACBL Recorder, who may send the information to the players’ committee.

The players’ committee will have final authority and the ability to eject teams from the event and recommend disciplinary proceedings against players, pairs, or teams that they believe to be cheating in any manner. The specific method of cheating does not need to be discovered for these steps to be taken.

Further, penalties for being found to be cheating in this event, as all ACBL online events, are the same as in live ACBL events, and may include, but are not limited to, probation, suspension, loss of masterpoints or titles, or expulsion.
