Sophists were not limited in their speeches only to topics in which they were aware. For them, there were no topics they could not dispute, because their skill reached such a level that they were able to talk about completely unknown things to them and still impress upon listeners and the opponent. The main purpose was to pick an approach to the audience, to please it and to adapt the speech to it. Unlike Plato's approach, the Sophist rhetoricians did not focus on identifying the truth, but the most important thing for them was to prove their case.
