Full disclosure - I am a coach. As this is first and foremost an educational activity, I have a few simple rules regarding conduct and content of the debate.
1) This is a debate, not a sound bite contest. Proper debate cannot exist without clash. If you bring up a point in C1 and it's never mentioned again, I'm dropping it from my decision. Obviously none of you thought it important enough to bring up again, so it must not be important enough for me to judge on.
2) Respect your opponent. Use your CX time wiseley to clarify the opponent's argument and find holes to exploit later in argumentation, or to perhaps plug up a hole you didn't realized you'd missed, not show off how much you can talk over the other person. And if you feel a need to resort to ad hominem attacks, you've lost me and we're done.
3) Deeply engage the topic, don't just recite a case. Yes, you absolutely must back up your claims with evidence, but don't make the sources do all the work. You've got to do your own analysis. Pro tip — creative arguments will get your judge's attention, since they've probably heard all the standard ones before. You're only going to make that happen if you take the time to really think hard about it on your own. And on a related note, I'd much rather see a few well-developed points with thoughtful analysis and solid foundational evidence than a "shotgun" approach where you throw out as many loosely-articulated arguments as possible and see what sticks.
4) I judge what happens in the debate. I will judge the outcome based on the merit of your arguments, regardless of how charismatically they were delivered. If both sides agree on a framework for deciding the winner, than that's what I'll vote on. If you don't agree on framework, then I'm left to determine my own, which will probably be based on what I judge to accomplish the Greater Good within the scope of the majority of the arguments. If aff defines a term or the motion in some way and neg doesn't contest it, than in the course of this debate that's what it means. If Neg runs a counter (non-negation) case or a counter-plan (assuming it's allowed), I'm going to judge it on balance with the aff case/plan, meaning I will decide which case better solves for all the harms. You should also know that while my ballot comments will probably bring in outside information, that information is intended to help you refine your arguments and did not influence my decision.
