DATC: Abbreviation for DIPLOMACY ADJUDICATOR TEST CASES.
Dateline: From the Postal Hobby, the heading under which Press is published. Not required in Online games, where Press is published in-game.

DBN: See DIPLOMACY BROADCAST NETWORK.
DBNI: See DIPLOMACY BROADCAST NETWORK INVITATIONAL.
DBS: Abbreviation for DRAW-BASED SCORING, an alternative name for DRAW-SIZE SCORING.
Dead Donkey: A player who, when a game has reached a deadlock, refuses to accept a draw proposal and thereby prevents the game from reaching a sensible end. Often means the application of a Deadlocked Game Procedure to force a game ending.
Dead Duck: A player who, for whatever reason, feels they should throw the game away in an act of vengeance. Partially named after Richard Sharp’s name for a player who, in a game, follows an unshakeable course regardless of what is happening in the game (an ARMOURED DUCK), a Dead Duck will pretend that they are KINGMAKING, throwing the game to another player to win. However, this is when the game is in too early a stage for a successful act of Kingmaking, meaning that the player is simply throwing their game away in vengeance, with nothing to show for it.

Deadline: The date and time you have to have your orders in. Online, this will be set automatically by the game. In any other form of Dip, it is set by the GM. Miss it and you should see your power’s units all given HOLD orders. However, some GMs and some sites allow a grace period or a holdover whereby players who missed the deadline are given another chance. Online you often find that you only have so many chances before being kicked from the game for missing a deadline.
Deadlock: A situation in a game in which no players are making any headway against any others for whatever reason. It may involve a STALEMATE but it may be that the players just don’t want to abandon their alliances, and therefore no progress can be made.
Deadlocked game: A game in which a deadlock has been reached and has existed for several game years. This may, or may not, involve a STALEMATE.
Deadlocked Game Procedure: The process by which a GM or game site ends a deadlocked game, usually forcing a DIAS draw.
Defence: The collective strength of a unit occupying a space that has been attacked and any units ordered to support that unit.
Defensive force: See DEFENSIVE STRENGTH.
Defensive strength: Sum of all units involved in the defence of a space.
Delight: Describes the feeling of a stab being successful.
Demilitarise: To move units from a space or spaces on the board to create a buffer zone between two players.
Demilitarised Zone (1): A space on the board which has been left empty as part of an agreement between players to create a buffer zone.
Demilitarised Zone (2): Alternative name for the Black Sea.
Demo Game: A game played to demonstrate how to play Diplomacy… which doesn’t work if you invite the wrong players.

Desert Rat opening: If Turkey opens with A Smy-Syr, they’re using this opening. Why would they? Because it discourages the LEPANTO opening by Austria/Italy.
Desperation: Following on from FEAR, trying to break down the door to the bathroom.
Deutschnaut alliance: An alliance featuring Germany, Russia and Turkey. Formed by combining Deutsch (=Germany) and ‘naut’ from Juggernaut, the Russo-Turkish alliance.
DEW: See DISTANT EARLY WARNING.
DGP: See DEADLOCKED GAME PROCEDURE.

Dip: Abbreviation often used for Diplomacy.

Diplicity: Newest of the Dip sites. Diplicity was originally launched as a Diplomacy App, but this became unsupported in August 1994. The only really disappointing aspect of this site (in comparison to other Dip sites) is that the Spring 1901 deadline is not double-length. Whether the site itself is still being supported, I’m not sure, but still somewhere to play Dip. https://diplicity.com/
Diplomacy Adjudicator Test Cases: An extensive set of test cases to ensure that automated judges adjudicate according to the rules. Most websites use these, or something similar, to ensure their adjudications are correct. They need updating when new rules are introduced. The most up-to-date version was put together by Lucas B. Kruijswijk and can be found here: https://boardgamegeek.com/filepage/274846/datc-diplomacy-adjudicator-test-cases (you need to be aware that the file is copyright protected!). This version is compliant with the 2023 Ruleset.1

Diplomacy Games Podcast, The: Podcast covering a wide range of Dip-related material: https://diplomacygames.com/
Diplomacy Skill Index (DSI): Fiendishly silly ratings system for players, based on a DSS system which was weighted by the power you played.
Diplomacy Variants Commission (DVC): An organisation for Variants. After all, we can’t just have any old variant being put out there, can we?
Diplomacy Widowers Association (DWA): A ghost organisation that never existed because women can’t play Diplomacy, and so no man will find himself in this situation. Apparently.
Diplomacy Widows Association (DWA): A ghost organisation for women who have to put up with being taken on “holidays” to far-flung places by their husbands, only to find themselves thrust together with other women while their husbands cuddle each other around a table with a Diplomacy board on it. Not to be confused with the DIPLOMACY WIDOWERS ASSOCIATION.

When Dolchstoss relaunched in 1984, Sharp renamed it the DRS. Similar to some other rating systems, very heavily affected by cross-game and out-of-game inputs.
Double Bluff: The somewhat over-the-top act of promising to do something in such a way as to make it seem that you’re not really going to do it, and then doing it. The idea is to have your “ally” believe you’re not going to do what you say you are, only to feel bad for thinking that way, so that they will lie on barbed wire for you in the game.

Draw (3): The power you have been allocated to play.
Draw-Based Scoring (DBS): Alternative name for DRAW-SIZE SCORING.

Draw proposal: An act whereby one player will suggest that the game should end in a draw, leading to a draw vote.
Draws Include All Survivors: The official way a game ends in a draw. All surviving players vote to end the game, and each player shares equally in the draw, regardless of how many Supply Centres they hold.
Draws Involve Nominated Survivors: Alternative to Draws Include All Survivors, in which all surviving players vote on a draw proposal, which may not include all the survivors. Sketchy way to end the game.

DRS: Abbreviation for DOLCHSTOSS RATING SYSTEM.
DSI: Abbreviation for DIPLOMACY SKILL INDEX.
DSS: Abbreviation of DRAW-SIZE SCORING.

Dumb mistake: Any simplistic mistake in the presented orders. There are three categories: [1] Mis-writing or mis-entering an order: this is when a player may write F Nth-Nwy (instead of F Nth-Nwg – which is why sea spaces should be in UPPER CASE, people! Online, it may be A Gas-Spa (instead of naming the coast – only a mistake if not deliberate). [2] Incoherent orders: when the order doesn’t match others, especially with support and convoying (eg A Lon-Bel, F ENG C Lon). [3] Failing to defend an easily defensible space by not ordering correctly, eg F Lon H, F ENG H; F Bre S MAO-ENG. See MISTAKE.
