I love debate and I will do my absolute best to make a decision that makes sense and give a helpful RFD.
Topicality
Competing interpretations are easier to evaluate than reasonability. You need to explain to me how we determine what is reasonable if you are going for reasonability. 
Having said that if your intep is so obscure that there isn't a logical CI to it, perhaps it is not a good interpretation.
T debates this year (water topic) have gotten too impact heavy for their own good. I've judged a number of rounds with long overviews about how hard it is to be negative that never get to explaining what affirmatives would be topical under their interp or why the aff interp links to a limits DA and that's hard for me because I think much more about the latter when I think about topicality.
T-USFG/FW
Affirmatives should be about the topic. I will be fairly sympathetic to topicality arguments if I do not know what the aff means re: the topic after the 1AC.
I think teams are meming a bit on both sides of this debate. Phrases like "third and fourth level testing" and "rev v rev debates are better" are kind of meaningless absent robust explanation. Fairness is an impact that I will vote on. Like any other impact, it needs to be explained and compared to the other team's impact. I have also voted on arguments about ethics, education, and pedagogy. I will try my best to decide who wins an impact and which impact matters more based on the debate that happens.
I do not think the neg has to win a TVA to win topicality; it can be helpful if it happens to make a lot of sense but a forced TVA is generally a waste of time.
If the aff is going for an impact turn about debate, it would be helpful to have a CI that solves that impact.
DA’s 
I would love to see you go for a disad and case in the 2NR. I do not find it persuasive when an affirmative team's only answer to a DA is impact framing. Impact framing can be important but it is one of a number of arguments that should be made.
I am aware the DA's aren't all great lately. I don't think that's a reason to give up on them. It just means you need a CP or really good case arguments.
K's
I really enjoy an old-fashioned k vs the aff debate. I think there are lots of interesting nuances available for the neg and the aff in this type of debate. Here are some specific thoughts that might be helpful when constructing your strategy:
1. Links of omission are not links. Links of “commission” will take a lot of explaining.
2. Debating the case matters unless there is a compelling framework argument for why I should not evaluate the case.
3. If you are reading a critique that pulls from a variety of literature bases, make sure I understand how they all tie to together. I am persuaded by aff arguments about how it's very difficult to answer the foundation of multiple bodies of critical literature because they often have different ontological, epistemological, psychoanalytic, etc assumptions. Also, how does one alt solve all of that??
4. Aff v. K: I have noticed affirmative teams saying "it's bad to die twice" on k's and I have no idea what that means. Aff framework arguments tend to be a statement that is said in the 2AC and repeated in the 1AR and 2AR - if you want fw to influence how I vote, you need to do more than this. Explain how it implicates how I assess the link and/or alternative solvency. 
5. When ontology is relevant - I feel like these debates have devolved into lists of things (both sides do this) and that's tough because what if the things on the list don't resonate? 
CP's 
Generic counterplans are necessary and good. I think specific counterplans are even better. Counterplans that read evidence from the 1AC or an aff author - excellent! I don't have patience for overly convoluted counterplans supported by barely highlighted ev.
I do not subscribe to (often camp-driven) groupthink about which cp's "definitely solve" which aff's. I strongly disagree with this approach to debate and will think through the arguments on both sides of the debate because that is what debate is about.
Solvency deficits are a thing and will be accounted for and weighed along with the risk of a DA, the size of the DA impact, the size of the solvency deficit, and other relevant factors. If you are fiating through solvency deficits you should come prepared with a theoretical justification for that.
I am generally neg leaning on cp theory but if you want to make an argument about why a certain cp is illegitimate (cough, con con) I will do my best to objectively evaluate that argument.
Other notes! 
Some people think it is auto-true that politics disads and certain cp's are terrible for debate. I don't agree with that. I think there are benefits/drawbacks to most arguments. This matters for framework debates. A plan-less aff saying "their model results in politics DA's which is obviously the worst" will not persuade absent a warrant for that claim.
Love a good case debate. It's super under-utilized. I think it's really impressive when a 2N knows more about the aff evidence than the aff does.
Please don't be nasty to each other; don't be surprised if I interrupt you if you are.
I don't flow the 1AC and 1NC because I am reading your evidence. I have to do this because if I don't I won't get to read the evidence before decision time in a close debate.
If the debate is happening later than 9PM you might consider slowing down and avoiding especially complicated arguments.
There was once a team who lost an "ethics challenge" because they capitalized a letter in a 1AC that had not been capitalized in the previous version of the 1AC -- that is not actually an ethics challenge. If you make a frivolous or convoluted ethics challenge in a debate that I judge I will ask you to move on and be annoyed for the rest of the round. Legitimate ethics challenges exist and should/will be taken seriously but ethics challenges are not something we should play fast and loose with.
For debating online:
-If you think clarity could even possibly be an issue, slow down a ton. More than ever clarity and quality are more important than quantity.
-If my camera is off, I am not there, I am not flowing your speech, I probably can't even hear you. If you give the 1AR and I'm not there, there is not a whole lot I can do for you.
