Pre-Writing Aff and Neg Blocks
Because you never know which side you'll actually get called to argue, competitive preppers write both aff and neg material for their strong-pile bills in advance. This lesson shows you how to write blocks that survive contact with a live round.
Blocks, not speeches
A 'block' is a modular chunk of argument — one contention with its warrant and one piece of evidence — that can be dropped into a first speech, a rebuttal, or an answer to a question. Pre-writing full speeches wastes time because half of it becomes irrelevant once the round starts; blocks are reusable.
Write neg even if you love the bill
Chambers assign speakers to sides somewhat unpredictably, especially after several speeches on one side. Write at least two neg blocks for every bill you're passionate about affirming, so you're not stuck improvising against your own instincts.
Anticipate the predictable clash
Most bills have 2-3 clash points that come up in almost every round on that topic (funding realism, agency capacity, unintended consequences). Pre-write blocks that directly answer those predictable clashes rather than only building your own case in a vacuum.
Pro move: the 'steal-proof' block
If you know a bill will draw many speakers, write your best block around an angle unlikely to be taken by the first five speakers — a second-order impact, a comparative advantage over a similar past policy, or a rebuttal to an objection you predict will surface only in later speeches. This keeps your speech from being 'the sixth generic aff.'
Bill: a national soda tax to fund school lunch programs.
Aff block: 'Contention 2 — Revenue is stable. Similar city-level soda taxes (Philadelphia, Berkeley) have generated consistent year-over-year revenue even as consumption dipped, per Tax Foundation data.' Neg block, pre-written in case you're assigned negative: 'Contention 1 — Regressive taxation. Soda taxes disproportionately burden low-income households who spend a higher share of income on groceries, per Brookings analysis, undermining the bill's equity goals.' Both are ready before the round starts.
1. Why write blocks instead of full speeches during prep?
2. True or False?
"You should only pre-write blocks for the side of the bill you personally agree with."
3. By the time you're recognized, four previous speakers have already made your top aff argument. What's the best use of your pre-written blocks?
