Starting points for discussion of TTPs:
Tactics -- thinking about what type of tactics you'll want to focus on in your games, the patterns for movements that are likely to come up, such as Openings, and how to use the map to your advantage, Stalemate Lines. Tactics will involve both military skills and diplomacy, i.e., communication skills, teamwork, and leadership.
Techniques -- consider the different techniques to effective gameplay: at the heart of Diplomacy is the negotiation skills you'll need to balance yourself between six other players. Deals and alliances are made and broken during the game, and no one can be certain whether other players will react as expected; the only thing you can control is your own techniques for problem-solving and dealing with any arising situation.
Procedures -- thinking about the procedures of the game that will be common to all Diplomacy games; Introductions; Opening Moves; securing allies; managing and maintaining diplomacy even with your enemies; always being prepared for stabs and surprise attacks; reaching stalemate lines to prevent solos. Being aware of expected procedure is important and players will have expectations; such as sending messages to your neighbours before you ready up (try to avoid readying up without first communicating with your neighbours).
Do people have particular TTPs that they adhere to, personal rules that might be useful for other players?
Are there certain procedures or good practice that you prefer to see?
Good forms of opening communications? Keeping it short and precise, or expanding on long-term visions even in Spring 1901?
