Some important technical info:

The players of the tournament will gather in predefined locations in their country.
- Each location has to have 1 responsible non-participating individual ("coach") who will ensure that the tournament rules are followed.
- The "coaches" can be approved/assigned by the renju federation of that country.
- The "coach's" responsibility is to notify the organizing committee of the championship about the details of the location no later than July 8, 2021. That includes the list of players who will be using that location and the number of video cameras that will be monitoring the location during the event (more details below), the name of the "coach", and the email address of the "coach".
- Each playing location should have as many computers with the Internet connection as there are players for the purpose of conducting the tournament games.
- Each playing location should have one or more devices (phones, tables, other) with the sole purpose of using it for showing the live video of the location. It is mandatory during the active games, and optional during the break time.
- The video devices have to be installed (for example placed on tripods) so that all the players of that location are clearly visible during the active games. One camera view can cover multiple players.
- In parallel with the games platform ( we will be using Microsoft Teams ( as the platform for connecting all the video sources together.
- The purpose of connecting the video streams from all the locations together is to create a good friendship connection and atmosphere for the tournament, and also to allow referees have full overview of all the players.
- After July 10., 2020, the organizing committee will send out the detailed description of the use of the video conferencing under Microsoft Teams. It is not required to register an account for Microsoft Teams. When being invited, the devices with the video camera can simply connect to the event. While joining the video conference, the user will be asked to provide a name for their video channel. Please use the name that contains both the name of the location as well the position of the camera, or sequence number if the position cannot be described well. For example "Tallinn, Main View" or "Macau #1".
- You can send your questions about video related topics to Ando Meritee ( in advance, including, if you would like to test the Microsoft Teams meetings in advance.
- It is recommended to keep the video channels muted normally, to avoid echo and unnecessary noise, and only unmute when making speeches or conversations with the other locations.
- The main hosting computer of the video conferencing will be located in Estonia, at the tournament location (Laagri school). If you happen to disconnect at any time, you can simply re-connect again as soon as possible.
- You can relocate the cameras or change their quantity during the event any time you like, as long as the minimum conditions are met (all active games are visible).
- Beware of the bandwidth conditions of your location. Make sure that you have enough upload and download bandwidth to have successful multi-way video conferencing.
- In addition to the dedicated video devices, each location may also consider adding a PC/laptop with the large monitor or connected projector, which will also connect to the video conference and show the matrix of all video users on the larger view for everyone at the premises to see. The tournament organizing location at Laagri, Estonia, will be using a very large wall screen with the help of the projector to give the participants a great feeling of being connected with each other visually.
- The players in each location have to follow the same rules as in case of the live face to face tournaments. The players and observers should not talk in the live games room, also, any kind of game assistance (human and computer) is prohibited. The players are allowed to stand up and walk around the tournament room (within the view of the camera) during the games. The players may look at the other players screens, as in real life tournaments, but not communicate and disturb anything. Leaving the game room during the live game is not allowed in the isolated locations, such as homes. It is only allowed in the official club locations, with the approval of the referee and when accompanied by the "coach".

About using a real board together with computer. For the main goal is to avoid staring at the monitor and have an opportunity to look at the board instead. Of course, camera coverage must include this board. Player, using a real board MUST make move first in and later copy same move on board. Of course, NOT any analysing can be made on board
