Arka50 is the 2017 Atomic World Champion!

The rules under which this edition of the World Championships were played are as follows:

Entrant Eligibility:
Entrants who meet the below criteria will be accepted automatically:

Have an established atomic rating on lichess;
Have played at least 250 rated atomic games on lichess;
Have had an active playing account on lichess for over 6 months at the time of entry;
Be participating ONLY using their main account (no dupe accounts);
Have messaged the TD (tipau) with intent to join WITHIN the entry period;
Have joined the Atomic World Championship group

Points 1-3 are aimed primarily at preventing duplicate accounts from entering. Entries not meeting these criteria may still be accepted and seeded at the TD’s/Entry Approval Panel’s discretion.Exceptions are most likely to be made for players known within the atomic community who are clearly not duplicate accounts.
Any player attempting to use multiple accounts or computer assistance will be kicked out and if necessary reported to lichess moderators.

Knockout Tournament Rules:
You will be paired with a player for a round. There will be one week for you to arrange a time and complete the games. Please note the following stipulations:

All games are by default unrated. If BOTH players agree then some or all games can be rated.
Results AND games of each match should be communicated to the TD upon completion.
Each match will consist of TEN games of 3 2.
Either player can stop the match if someone reaches 5.5 points in the first 10 games, as long as the player stopping the match has not played more rated White games than their opponent.
If the score is 5-5 after 10 games then two pairs of tiebreak games of 3 2 will be played, with the match stopping if one player is ahead after an even number of games.
If the score reaches 7-7 without a winner then an armageddon match will be played. Black will have 3 minutes and draw odds. Each player will message the TD a time offer for White, with the lowest offer playing White. If the offers are identical the higher seed will play White. There will be no increment.
A player can request a maximum of 2 breaks between games, of approximately 10 minutes, during a match.
The tournament main draw will have either 16, 32 or 64 players.
- If the number of entrants is below 16 the tournament will not go ahead
- If the number of entrants is not below 16 but not equal to 16, 32 or 64 then a qualification round will take place
- The qualification round will involve the lowest seeded entries and eliminate the required number of players for the new total to be the highest possible out of 16, 32 or 64
Any entered players who lose in the qualification round may be used to substitute for any defaults in the first round. If required the substitute player will take over the seed number of the defaulted player.
Assuming there are 64 players, after the first round there will be 32 players left and so on until there are 2 players left. There will be a maximum of 6 rounds.
The initial pairing will have the top seed vs bottom seed, the second seed vs second from bottom etc. For example in an eight player event: (1) v (8), (2) v (7), (3) v (6), (4) v (5). The winner of (1) v (8) will then play the winner of (4) v (5) and the winner of (2) v (7) will play the winner of (3) v (6). The winner of those matches would then contest the final.
The seeding will be based on the average between a players current rating and highest rating at the time their entry is received & logged.
If somebody is unable to complete a series, or has to withdraw, then their opponent is considered the victor. Byes may be issued in the case of an odd number of players.
If someone knows they will not be able to play a certain week when a round is scheduled they must notify the TD BEFORE they play their PRIOR match. At the TD’s discretion their match may be moved to the following week. This will only occur a maximum of 1 time per player.

Match Negotiations:

Players may begin negotiating a playing start time as soon as their next pairing is known.
Each player is responsible to offer at least 3 separate times for the match, by Wednesday at the latest, unless an offer has been accepted before that number is reached.
The 3 offered times should be no closer than 3 hours to each other and no more than 2 on a single date.
If 3 offers are not made in time the player at fault must accept a time chosen by the opponent.
If both players fail to make 3 offers by the deadline then a match arbiter will assign a time.
A player should respond to an offer by accepting or making a different offer, preferably within 24 hours.
If a player is excessively or repeatedly late for scheduled matches they may be forfeited.
If both players make 3 offers but no agreement is made before the weekend then a match arbiter will determine if fault lies with a particular player.
If a player is at fault then their opponent will decide the match time, if no player is at fault the match arbiter will assign a match time.

Reporting (C)heats:

Accusations of cheating must be made privately to a member of the anti-cheat panel.
The accusation must make reference to at least one specific game.
If an accusation is made publicly and does not lead to a guilty verdict the accuser will be forfeited & banned from future events.
The anti-cheat panel must all believe a player to be guilty 3-0 for a player to be forfeited. 100% proof is not required.
If a member of the panel is either the accuser or accused their place on the panel will be taken by another.
