5.3 Power Selection (Paris Method)

  2. GM’s shall keep the health and well-being of players in mind. Players may request games to be briefly paused which the GM shall allow at their discretion. 
  3. If the GM finds that a player is intentionally abusing grace periods or pauses to create an advantage or frustrate other players, it shall be considered a code of conduct violation. Players abusing grace periods will be given one warning by the GM. If the behavior continues a second time, the GM will process as if no moves were received for the abandoned power. If the behavior continues a third time, the player abusing grace periods shall be removed from the tournament and an alternate player will be found using the rules for Civil Disorder and Replacement Players.

When using Discord voice channels, it is acceptable to briefly drop into a negotiation room where other players are communicating, request to speak to one or more players, and then immediately leave the channel if requested. Players are under no obligation to speak to one another. Players are permitted to drop-in more than once during a negotiation period if necessary, but this should not be abused. 
  4. Performing actions that intentionally prevent someone from having a private conversation in a negotiation room, such as following someone around or refusing to leave if asked, is considered a code of conduct violation.

In the event that there has been no exchange of centers for at least three consecutive years, the GM, at their discretion, may end the game in a forced draw.  If the GM determines that players are exchanging centers merely to avoid triggering this rule, the GM may, at their discretion, end the game in a forced draw.

5.7 Draw Proposals

  1. Beginning in Spring 1907, players may propose a draw once per Spring or Fall season by announcing their intent to draw in the game table, and then requesting the GM to adjudicate the draw. Once everyone is in the Game Table, the GM shall give players the opportunity to openly veto the draw. If the draw is openly vetoed, it does not count as the draw vote for that season. If it is not openly vetoed, each player shall head to their assigned voice room and confidentially cast their vote to the GM. 
  2. If a player proposes a draw, and one or more players decline to congregate in the Game Table, those players shall be considered to have openly vetoed the draw. The GM shall not force players to go to the game table for a draw proposal.
  3. For a draw vote to be successful, every player that controls at least one supply center at the time of the vote must vote in favor of the draw. The GM shall not divulge who voted in what way, or how many players voted for or against the draw.

5.8 Civil Disorder and Replacement Players

  1. If a player experiences technical issues that prevent them from participating in voice negotiations via Discord or entering orders in Backstabbr for a period of time that exceeds one hour, the GM shall seek out an Alternate to serve as a replacement player. At the GM’s discretion, if the original player’s technical issue is resolved before the Alternate takes over as the replacement, the original player may continue play. 
  2. If an emergency dictates that a player must leave the game early, the GM shall seek out an Alternate to serve as a replacement player. 
  3. In the situation where an alternate player cannot be found, the GM shall process standing “hold” orders for the abandoned power and assume a vote in favor of all draw proposals
  4. Players replaced by an Alternate are no longer eligible to participate in any games for the remainder of this year’s DBN Invitational.
