Just to give some context about my debate history: I debated for four years in high school with Dallas Jesuit. I went to Emory, but did not debate while I was there. While in college, I did occasional work for Jesuit and coached/judged at some national tournaments. After graduating, I spent two years coaching and judging at Jesuit before going to law school. I'm currently in my second year and have limited judging experience on this topic (several rounds at the Texas state tournament in March 2019).
Framing is good - explain why your links supersede the link-turns, why the solvency deficit on the counterplan means you win on disad mitigation, etc. Tell me how you want different parts of the flow (and different pages of the debate) to interact.
I get annoyed by bad highlighting - that is, highlighting that reduces sentences into fragments and phrases that don't coherently fit together. If your opponent reads a card that is severely under-highlighted, and tries to extend warrants that weren't actually in the highlighting, point that out - I'll be receptive.
My speaker point range is usually 28-29 - I find myself going above that more often than I do going below that. If you want good speaks: line-by-line, clash, and be fast but clear (and smart, but that should go without saying).
I like to be included on email chains. I don't scroll/read through the docs during speeches, unless I get worried about clipping cards.
Slow down. No, really. Slow. Down. Conditionality is probably good – multiple conditional worlds that contradict each other are probably less of a good thing. Most other theory arguments are probably a reason to reject the argument and not the team (yes, even if those blippy theory arguments are conceded) - maybe you can convince me otherwise. You should be talking about the impacts to your theoretical objection (or counter-interpretation) just as you would for any other argument.
When schools break a truly new Aff, they should not have to disclose anything about the substance of that Aff to the Negative before the round. I think that is a powerful incentive for people to innovate. It will be almost impossible for you to convince me otherwise. An Aff that is new to a particular pairing but that has been previously broken by another team from the same school is not "new."
At the end of the year, against Affs that have been run for awhile, Neg teams might need to focus more on why the particular Aff's un-topical-ness is bad (not necessarily in-round abuse, but a reason their Aff, and not necessarily what they justify, makes it harder for you to debate). Links and impacts should be discussed just as they would any other argument. I do not think that the limits debate is necessarily the most important standard. I default to competing interpretations (unless a compelling argument against that default can be won), so it is important that you talk about what other debates (not just your own) would look like under your interpretation (my earlier caveat about end-of-the-year debates changes this a bit). Evidence on topicality can be very useful and strategic, but is by no means necessary.
PICs and agent counterplans are usually okay – agent counterplans that play fast-and-loose with excessive amounts of fiat may be less okay. States counterplans are probably okay, especially if you have a solvency advocate.
I’m not the biggest fan of process counterplans, unless those counterplans come with evidence/a solvency advocate (preferably specific to the Aff). That said, a solvency advocate isn't a death knell to the Aff - if you think their process counterplan is bad for debate, tell me why.
All of the above is debatable. I'll vote for a counterplan I don't like if the Aff doesn't win.
As far as framework goes, Aff’s probably get to weigh the action of the plan. Links and impacts should be discussed (and labeled as such) just as they would for any other arguments. It’s probably important that the link is specific to the Aff – even better if you have multiple links specific to the Aff. It’s also probably important that your alternative solves the Aff harms, or at least makes some attempt to. The Negative should bring up and defend what they think the role-of-the-ballot should be.
Thoughts on "non-traditional"/"performance" Affs: Here's my starting point: I think plan texts are probably good, and that the Aff should probably engage (at least some of) the specifics of the topic/resolution. That said, I’m sympathetic to the need to have discussions in the debate space that don't necessary follow those criteria. But I’m also sympathetic to the Neg’s need to, frankly, have something predictable to debate against. Debate isn't just a platform for advocacy, and it isn't just a game - it's a little bit of both combined to make something else entirely. I think that Negatives going for framework or topicality against these types of Affirmatives can get a lot of mileage out of arguing either that there is a "topical" version of the Aff, or that switch-side debate solves. That said, I don't want this to dissuade you from running these Affs in front of me - but if your access point is something other than a plan text, and the pref sheet doesn't prevent me from judging you, I want you to know my usual leanings and still be able to win. I'll judge what gets debated in-round - if you win that your type of advocacy is needed (that your education is uniquely good and uniquely a product of what you're doing in the debate round) and not all that bad, you'll win the round (especially if the Neg isn't doing a good job contesting those points). Tell me why the topical version of the plan doesn't do the trick, tell me why the discussions the Neg wants us to have aren't important/useful, read some great literature that backs up your point of view, etc. Teach me something new - I'm here to learn, too.
