How to run Multi-Session Pairs

You can split a single pairs event over multiple sessions. You can play a different number of rounds in each session.

We will demonstrate this with an example of an 11-table, 21-round Howell, split over two sessions of 11 rounds and 10 rounds. The same method works for Mitchell movements and Swiss pairs.

Revised 15 February 2021


Step 1: Set up the first session

Log in as the Director and set up the first session, putting in just the rounds for the first session.

session settings single set

As usual, put in the event/session name in the yellow band at the top of the lobby window.

Set the scoring method to Pairs and the movement to Howell

Put in just the 11 rounds for the first session.


Step 2: Run the session

Suggestion: When everyone is seated, take a screenshot. This may be useful in later sessions, if you want to make sure people are sitting in the correct seats.

Start the first round, and run the event to the end of the session as normal.  In this example we are only playing eleven rounds, so it will be when all tables say “R11”.


Step 3: Export a config file containing the current state of the event

At the end of the session you will see all the scores. These will be carried over to the next session.

Go to Advanced, and export config.

export config

The file will be ready to download in the chat box in the lobby:

save config file

Keep this file.

You will not use this session again. As a precaution, however, it is best not to destroy the session until you have started the next session.


Step 4: Set up the next session and load the config

For the next session, create a new RealBridge session with new links.

Give this new link to the players, but don’t open the session yet.

Go to Advanced. Load the config file that you exported from the previous session.

advanced session config

You will notice that most of the settings will be populated automatically. This includes player names (and ids, if they used them), number of tables, number of boards per round, and carry over (C/O) scores.

The number of rounds will not be populated from the config file – it will be set to the default of 2.


Step 5: Check and amend settings

Check that all the settings are correct, and amend them as necessary.

In particular, set the number of rounds to the number that you want to play in this session. This can be more or less than in the first session. In this example, we will set it to 10.

Important: Do not change the number of tables.

Note: the starting tables will be different from what they would have been if you had simply continued the previous session. However, the players will be playing against the correct opponents, and the movement will continue correctly.

What you can see and do:

  • See the carry over scores from last session.
  • See the sum of the last sessions and the current session in total.
  • Assume that the movement will continue from where you stopped.

What you cannot see and do:

  • See the boards played in the previous session. (Use the previous session’s links to view these on RealBridge, or save output files and upload to your own scoring platform ie BridgeWebs, etc.)

When you are ready, open the session to the players.


Step 6: Play the second session

When the players arrive, they must use the same names (and ids) as they used in the first session. If they do this, they will be seated automatically in the correct place to start the next round.

If a player logs in using a different variation of their name (eg slightly different name, different case, extra spaces), they will arrive in the lobby.  If this happens, ask them to refresh the browser window, and log in again using exactly the same name (and id) as last time.

Do not add or subtract pairs or tables.

If you had a sit-out pair, do not replace it with a real pair.

When you are ready, click Start Round 1, and the event will continue.


Subsequent sessions

If you are playing further sessions, follow the same procedure: save the config file at the end of the session, then load it into a new RealBridge session for the next session.

Multi-Session events and X-Imps

Session 1: the X-Imps are for those boards.
Session 2: carry-over scores from session 1 are loaded at the start of session 2.
On the X-Imp list, showing the pairs listed in order of rank, the X-Imp scores are for the event so far.
That is, they are for the average of all boards, in all sessions.


At the end of the event

If you save a USEBIO file from the final session, that will contain the final scores for the entire event, including the carried-over scores from the earlier sessions.


Advice

Do not keep using the same RealBridge link for multiple sessions. A RealBridge session is intended for a single session of bridge. RealBridge provides a mechanism for carrying over the data from one session to the next.

When you save the config file, give it a name that makes sense. The name should identify the event, the date and the round numbers.

If you are playing more than two sessions, you will have more than one config file.  Give them different names – don’t overwrite the first file with the second one.
