4. Qualifying Stage

 

The qualifying stage will be played in the form of a Round Robin and will consist of 154 boards played in 11 matches of 14 boards each.

 

The results of each match shall be converted into Victory Points in accordance with the appropriate WBF IMP/VP scales (see p. 10 below).

 

A team will receive 12 VP for any match that is a BYE.

 

In order to determine the grouping for the knockout stage, a tie between two teams will be broken by the result of the match between those two teams. If there should still be a tie, then the IMP quotient of all matches will be taken into consideration to break the tie.

 

The top 4 teams from the qualifying stage will advance to the knockout stage.

 

 

5. Knockout Stage

 

The team placed 1st in the Round Robin gets to choose the opponent for the semifinal from the teams placed 3th – 4th in the Round Robin.

 

Both semifinal and final will be played over 32 boards, 2 separate segments of 16 boards each.

 

There will be the following carry over:

  • in the semifinal no. 1 – 2 get a carry over of 10.1 – 6.1 IMP respectively;
  • in the final the higher ranked teams in the Round Robin get a carry over of 0.1 IMP as a tiebreaker.

 

 

6. Line-Up and Seating Rights

 

All matches of the Round Robin qualifying stage will be played without change of the line-up; unless there is a valid reason for a change, to be decided by the TD.

 

In semifinal and final change of the line-up is possible after each 16 boards with no restriction (separate segments).

 

Captains submit their line up without knowing the line-up of their opponents (“blind line-up”).

 

In the Round Robin qualifying stage the teams are expected to submit their line-up as soon as practical but in any case not later than 30 minutes before the start of the round.

 

Teams who infringe this regulation will be subject to VP penalties according to this scale:

  • 1st occasion – warning;
  • 2nd and any subsequent occasion – 0.5 VP penalty.

 

The line-up must be submitted through the line-up web utility. All captains will be provided with the respective link and the password.

 

 

 

7. Running the matches

 

All players involved must be online and logged in to Bridge Base Online 10 minutes before the start of the round at the latest.

 

Players must have their official name on their BBO profile. Private isn't allowed. Teams who infringe this regulation will be subject to VP penalties according to this scale:

  • 1st occasion – warning;
  • 2nd and any subsequent occasion – 0.5 VP penalty for each match for each player without official name on BBO profile.

 

The Tournament Director will create the tables and send invitations to the players in accordance with the submitted line-ups. Players are requested to accept the invitation immediately upon receipt.

 

All tables will play duplicated boards (same boards for every team).

 

The table settings will allow kibitzers but forbid communication between players and kibitzers.

 

Barometer scoring will be OFF. The scores are only visible (for the players) after the last board has been played. Kibitzers can see the scores during the match.

 

Undo and claiming: Mixed Team encourages the players to accept the opponent’s undo in the obvious misclick situations during the bidding as well as play. In case such undo is refused a player gets one “challenge” whereby the TD can be summoned to the table. Play must be shut down till the TD arrives. The TD will assess the situation, and if he believes the undo is justified by an obvious misclick that no reasonable player should refuse, the undo has to be accepted by the opponents.

 

Players alert their own bids. Bids must be alerted before entering the bids. If you don’t alert before making your bid, your opponent may think that your bid is natural, make his/her bid, then see the Alert and legitimately ask for an undo in case the information changes his/her perspectives.

 

If players explain bids via chat they should set the recipients to Opponents, not Table, so that only opponents see the explanation not partner. The best way is to explain the bids via the BBO alert mechanism.

 

Players may not consult their own system card and use any aids to their memory or calculation or technique between the commencement of the auction and the end of play.

 

If players experience highly suspicious plays, we encourage you to send a report to the organizers at mmt@bridgeresults.org. We will not reveal your name as source.

 

Players are expected to finish 14 boards within 1 hour 50 minutes; 16 boards within 2 hours. The Tournament Director may remove unplayed boards if in his opinion a delay in finishing the match in the allotted time would interfere with the smooth running of the competition.

 

 

8. Request of the TD ruling

 

The Mixed Team strongly encourages participants to play in the most respectful way. Any player can summon the Director to the table in case of irregularities. The time for a request for a TD ruling expires 30 minutes after the end of the match. All requests will be decided by a qualified Director (if appropriate - in consultation with other directors and/or world class players); no further appeal will be possible after the TD’s decision.

 

To submit protests, you should send email to: mmt@bridgeresults.org

 

 

9. These Regulations may be amended and augmented at the discretion of the organizing committee if circumstances so warrant so as to ensure the smooth, efficient and enjoyable execution of the events.

 

Although the MMT are not aligned with any bridge organization, we take ethical violations seriously and report to Eric Laurant from the WBF Investigation committee if our experts and statisticians find ground to suspect a pair/player is violating the rules of bridge through self-kibitzing or illegal communication with partner or teammates.
