Notes about scoring & movements

(changed 15 February 2021)

Neuberg

RealBridge now uses the Neuberg Formula.

Sit-outs in VP events

In a Swiss or Round Robin teams with an odd number of teams, using VPs, sit-out matches are scored as 12 VPs.

Similarly, in a Swiss Pairs with an odd-number of pairs, using VPs, sit-out matches are scored as 12 VPs.

These results are included in the USEBIO file.

Round Robin (2x1/2)

See here for the multi session round robin guide

• This new Round Robin teams format has an intermission halfway through the round.
• After the first half-round has been played, players will be automatically moved back to their home table. The table will indicate the status R1a and the following icon will appear

• Once the players have finished discussing the boards, the director can press this button to continue round 1.

• Note: The timer will start again for each half-round, so make sure the time is set appropriately. For example, if you are playing 16 boards per round, you must set the timer for approximately 55 minutes (the time it takes for 8 boards).

Board-A-Match (BAM) Teams

• These are scored using the European PAB method
  (0 = Loss, 1 = Draw, 2 = Win).
• BAM teams can be played as either a Head-to-head, Round-robin, or Swiss movement.
• The USEBIO button generates an extra pair of files with "_pairs" in the name which are the event re-scored as matchpoint pairs. This is necessary for some national ratings systems.
• In some countries, Board-a-Match is called Point-a-Board.

RealBridge Lounge

In Session settings choose Practice. Choose typically either 20, or 32 boards. Choose 1 round. Add some tables. Name them if you want. Open and start the session as normal. Players can join and sit in the seats. If you need to add more tables, you can do via the normal functionality for adding late tables. The logging system only charges for tables that were used.

Teams of 8

[Added 8th April 2021]

Teams of 8 or more is played between two (or more) large teams. Each team is made up of several teams of four (“constituent teams”). Each constituent team plays a match against each of the opposing constituent teams. In this example, the Red Team are sitting at tables 1 and 3. The Blue Team are sitting at table 2 and 4.

1.    Terminology

Team – Made up of several constituent teams, for example players from a particular club. Eight or more players per team.

Constituent team – A team of four, forming part of the larger team. This is different to a standard round robin where each group of four is a team of its own.

2.    Example of movement for constituent team 1

2. In round 1, constituent team 1 will play constituent team 2.
3. In round 2, constituent team 1 will play constituent team 4.

(Optional) If you want all pairs to play all opposition pairs, make sure you have 4 rounds and the movement described in the below config file. After round 2, swap NS and EW of one team. More details below.

1. In round 3, constituent team 1 will play constituent team 2 again.
2. In round 4, constituent team 1 will play constituent team 4 again.

3.    Set up

1. Create a normal session and distribute links normally.
2. Various options for configurations are in the appendix below. Adjust the config file with any changes you would like to make.
3. Upload the config file using the Advanced button.

4.    Play

1. When you are ready for participants to join, open the session.
2. Ensure players sit at the correct tables in their constituent teams.
3. When you are ready, click Start Round 1.

5.    (Optional) All opponents play each other

If you wish to have all partnerships play all partnerships on the other team, you must ask all the players from one of the teams to swap NS to EW and vice versa. The best practice for this is for the director to sit in the director’s seat and ask all players to leave and come back to the seat on their left, for example. The director will be able to see the movement and ensure partnerships remain constant.

The timings of when to perform this movement comes down to preference. There are two ways to set up the session, a double round robin or a round robin with a break (2x1/2). For a double round robin, you must have match assignments set with each constituent team playing each opposition constituent team twice. This is already done for all config examples in the appendix. You will need to ask players to swap seats after half the rounds have been played. For Round Robin (2x1/2) you will need to ask one of the teams to swap during each break before continuing to the next half of the round. This means you will need to swap every round.

6.    Teams of more than 8

You can set up the config file for teams of as many players as you like, for example, the figure below shows teams of 12.

7.    Simple Scoring

Aggregation must be carried out externally using the outputs from RealBridge. Remember to download results files before destroying a session.

There are multiple ways of scoring a Teams of 8 match, the simplest way is to sum the IMPs from all constituent teams in a team. For example:

The data from the green shaded part if found in RealBridge in the Scores by Round section. All you need to do is sum the two constituent teams to find the score of the overall team. Here, the constituent team Red 1 scored 33 and Red 2 scored -6, the sum of these is 27. Below is an example of the appearance of scores in RealBridge.

Other methods are found in the EBU whitebook.

8.    Appendix: Config File

There are several ways in which you can set up this session. The standard way would be as follows:

For two teams of eight.

{"name": "Red vs Blue",
  "num_tables": 4,
  "vp_scale": 0, 
  "scoring_break": false,
  "scoring_method": 17, 
  "team_names": [ "Red 1", "Blue 1", "Red 2", "Blue 2"],
  "time_per_round": 2520,
  "time_display": 1,
  "boards_per_round": 6,
  "num_rounds": 4,
  "match_assignments": [
    [ 2, 1, 4, 3],
    [ 4, 3, 2, 1],
    [ 2, 1, 4, 3],
    [ 4, 3, 2, 1]
  ]}

The match assignments here follow the example given in Section 1. If you only wish to play 2 rounds in total, you can remove the last 2 rows in the match_assignments matrix. Be sure there is no comma after the final row, as seen above.

If you are running a multisession event and wish to resume after round 2, the match assignments will be saved in the config file you export, no editing is required in the exported config file.

If you are running a session with teams of more than 8, you can use one of the following movements.

[2,1,4,3,6,5],
[4,5,6,1,2,3],
[6,3,2,5,4,1],
