I have been a coach for several years and during this time, I judge often. One of the most important things I look for when judging is that your arguments make sense and are supported with reasoning and evidence. The most unique and crazy argument will not necessarily win over a stock argument if you can't argue it well. But, if it is well supported and explained with solid links, then go for it! If you have a partner, you need to share the work load and have an actual partnership. Always maintain decorum! Do NOT speak so quickly that I cannot follow what you are speaking. I like to flow the round and if I can't write down what you are saying, then something important will be missed. There must be clash but don't get hung up on one point.
