This is the Second Affirmative Constructive, or 2AC. This is the Aff’s chance to rebuild their case and attack the Neg’s offcase positions. 8 minutes long in high school and 9 minutes long in college, the Aff will want to get through their own case in only a few minutes to leave plenty of time to dump answers to the Neg’s offcase positions.
While the Aff can almost never win the debate in the 2AC, they can lose by undercovering key Negative arguments. An argument missed in the 2AC cannot be answered new in the 1AR, as this is the Aff’s last constructive.
