This is the Second Affirmative Rebuttal, or 2AR.
This is the final speech of the debate, where the Aff has the chance to consolidate and makes things clear for the judge. This speech is relatively easier than the 2NR since it is reactive and can make choices based on 2NR missteps.
The 2AR will begin usually by rebuilding part of the Aff case, going for one advantage. Then, the 2AR will go in-depth on 1-2 key arguments against the 2NR’s position, attempting to out-explain and out-spin the 2NR.
