Lincoln-Douglas debaters get a brand new resolution every two months, and most families outside the activity have never heard the term "topic brief." It's the foundational research document a coach writes before a new topic starts: what the resolution actually asks, which authors matter on each side, where rounds tend to get decided, and a first case outline for a student who has never touched the topic before. Every serious program writes one internally. Very few make theirs public.
This one is Podium Debate's own brief for the current national LD topic, written by Sachin, who has personally coached a Tournament of Champions finalist. It's built for students starting the topic cold as much as for the coaches and parents supporting them. Nine parts, in order: how to read the resolution, a map of the five camps of authors who write on it, the definitions that actually decide rounds, the burden structure, six affirmative positions, seven negative positions, how the two sides tend to collide in an actual round, two starter case skeletons, and a research assignment list for what to cut next.
It's free for anyone, not a members-only file. The free case files already circulating in novice LD (Kankee Briefs, Triumph Briefs, Value Criterion, DebateUS) rarely go this deep on a brand-new topic in its first month, and a new team shouldn't have to pay just to find out what the resolution means. If your student is working through this topic and wants to talk it through with a coach, that's exactly what a placement session and a live cohort are for, but the brief itself isn't the pitch. Read it, argue with it, and go find better evidence than what's already in it.
