I FLOW ON PAPER. I judge debates much more effectively / think harder about the debate / give better comments when I flow on paper. This is the only thing that I wish debaters would more effectively adapt to – give me a little pen time when you transition from card to card / arg to arg and please consider that I have to flip sheets between arguments.   I believe judges should adapt to the debaters, not the other way around. I will do my absolute best to objectively and fairly judge your debate, regardless of the arguments you choose to read. I would much prefer that you read the arguments you’re interested in / are better at debating than attempting to adapt to what you interpret as my preferences based upon what I have written here.
I find myself to be a much more “technical” judge than I once thought, and by that I mean I tend to pay a lot of attention to the way arguments evolve as the debate progresses. That’s not to say that I don’t enjoy the 2NR / 2AR spin game, but that those “spins” need to be traceable to previous speeches. In addition, I have and will vote on technical concessions SO LONG AS there is an IMPACT to that concession – debaters concede irrelevant arguments all the time, as it turns out.
I evaluate debates in segments – I think each flow has compartmentalized “mini-debates” that take place within them that I evaluate piece by piece (for example, on a critique, the “link debate” “perm debate” “alt debate”etc etc, on a disad the “uniqueness debate” “link debate” “impact debate” “impact turn debate” etc etc etc). If you label these segments clearly and follow these segments throughout the debate, I will be a great judge for you and your speaker points will reflect your organization / flow tech.
WITH THAT SAID!! I do enjoy non-traditional flow and speaking styles, so do not be afraid to pref me if you debate with a different style – I judge these debates a lot and have no problem following / figuring out what needs to be evaluated.
I’m a very expressive judge. You will know if I am feeling your argument if you pay attention to my non-verbal communication. I believe debate is a communication activity and you, as debaters, should know how I’m vibing with your arguments throughout the debate.
Note about speed: Speed is fine, but please make your card / argument transitions clear with vocal inflection. If I miss an argument, 97% of the time it’s because I didn’t hear you say “and” and I thought you were still reading evidence. Your speaker points will reflect it if you SLOW DOWN on tags and don’t just read them like another piece of evidence. IMHO, debate is still a persuasive activity, and being persuasive gets you bonus points. I will always be fan of a slower, persuasive rebuttal.
I don’t think you will have an issue reading almost any argument in front of me, but since folks seem to just read philosophies to find out how people feel about K debate and framework, I guess I’ll say some stuff. 
Affirmatives: I think affirmatives should, AT THE VERY LEAST, be in the direction of the topic (but being topical is so much better). I think the best K affs have a resolutional component and have literature that is inherent to the topic. I can and have been persuaded otherwise, this is just my baseline.
Affirmatives should have a solvency method - I don't particularly care if that's an instrumental affirmation of US(fg) action or not (see FW discussion below), but you've gotta have a method that you have solvency for - I really don't like affs that state a lot of problems and argue that the revelation of those problems somehow does anything - that's not negatable. This is along the same lines of "advocacy" statements that don't take an "action" (I use the word action very carefully - I think a lot of things are actions). Statements are quite difficult to negate.
Framework/Topicality: 
I think topicality debates need to be SLOWER than other arguments - you want me to write down more, you need to give me more time to flow. In general, I DESPISE T debates that are read entirely off blocks and read at the speed of cards. I don't think this is helpful, I don't think this creates depth, I don't think this is good for education, and I'm probably flowing like 2 words / argument tbh.
I am significantly more persuaded by topicality arguments (ie: the affirmative needs to defend international space cooperation bc that’s key to limits) than framework arguments (ie: debate is a game, the affirmative needs to defend instrumental USFG action bc them’s the rules and and it's unfair and they are cheater cheater pants).
I think negative limits arguments have the capacity to be quite persuasive if teams go for the correct internal links based upon the aff / 2ac strategy. One of the biggest mistakes I see (primarily) 2Ns make is going for the wrong limits scenario. Just like any argument, some links are stronger than others, and you don't need every link to win in the 2NR, so pick the best ones that you think tell the most compelling limits story based upon the particular affirmative. Don't forget to contextualize limits arguments to the COUNTER-INTERPRETATION not (only) the aff itself.
Topical versions of the affirmative are important, but you have to actually explain WHY they are topical versions of the aff (ie how they meet your interpretation, even better if they also meet the counter interp) and how they address the affirmative team’s offense. Ev for TVAs is preferred. I don't think you need to have a TVA to win the debate.
Things that are not persuasive to me:
decision-making “People quit” “Small schools XYZ”
I’ll default to competing interpretations unless you tell me otherwise. Reasonability – how do I decide what is reasonable and by what metric do I use?
Critiques:
To make a link argument, YOU HAVE TO TALK ABOUT THE AFF. The aff has to have DONE SOMETHING that you have linked to an argument. I don’t think links of omission are links. If the 2NR is explicitly going for a link of omission, you’re going to have a hard time.
I don’t think criticisms always need an alternative (critique IS a VERB, after all). Make sure you explain how the "alternative" interacts with affirmative solvency / how they are different / how the alt accesses the aff (beyond just a generic root cause explanation).
I'm a sucker for K tricks - affs: don't get bamboozled.
Aff fw v ks: Often is an argument made in the 2AC that is just repeated over and over and not advanced in any meaningful way. If you think framework is important for how I evaluate the K debate, you need to do better than that.
“Role of the ballot”: 
I have significant problems with ROBs. I think "role of the ballot" is an empty and meaningless phrase. The "role of the ballot" is to let tabroom know who won and lost the debate. I don't think my ballot does anything for activism / changing the structures of debate / anything at all. I tend to think most ROB claims boil down to "ROB: Vote for me" which is silly af.
Now, this is different than telling me how to evaluate the debate, how I should filter impacts, how I should prioritize arguments, or in general, how I should make my decision. You can and must do that to win the debate.
Perm stuff:  Permutations are tests of competition, and that is all. That means if you read severance / intrinsicness - those are reasons to reject the perm, not the team (unless the negative team gives me a compelling reason for why the team should be rejected, tbh, haven't heard one yet.).
There is a lot of discussion about why competition standards for advocacies / methods should change when a K aff is read – eh, I’m unconvinced this is true. My default position is that your method should compete, which means, it has to withstand the permutation test. I could, perhaps, be persuaded that the affirmative shouldn't get a perm if the negative is willing to commit the time and energy to explaining why competition standards should change, how they should change, what debate looks like with those competition standards, how it applies in that particular debate, etc. Sound like a lot? Yeah, it kinda is... just beat the permutation with disads and solid link explanations.
You can be certain that I absolutely will not reject a perm on an assertion of "no perms in critical debates" or "no plan, no perm."
Case debate:is highly under-appreciated. Oftentimes 2ACs just assume the neg doesn’t know anything about the aff and entirely mishandle case arguments. Punish. Them.  I have and will vote on case turns if they outweigh the aff or if the aff has such diminished solvency that they outweigh the aff.
Theory: most theory debates are garbage. Prove me wrong. If there is one conditional K or CP, don’t waste your time. If the alt isn’t actually vague, make a different argument.
