The best way is to win a net turn to the case, typically a solvency debate. Yes, even a Clinton disad, although as mentioned, I think those are easier for the affirmative to pick spart. Back in the day, we considered this a case turn. Presentation is important. Ifyou speak clearly, articulate, and project, then I will find your presentational skills appealing.
Ifyour words are garbled, expect poor points.
And don't expect me to read or consider evidence I can't understand. In fact, this is a pretty sure route to loosing. Speaking ofevidence, I don't really read nearly as much as I once did. I have to be able to understand the cards, not just the tags. Don't skip words or I'll disregard your evidence and give you poor points.
