There are two main types of useful move in debate.

1) Characterizing. This is an attempt to paint a multifaceted, balanced, fair, objective picture all at once in as few words as possible.

2) Responding. This is providing a counter to what has been said and is typically dramatically far from complete. It is (often) intended to be one-sided. It may or may not acknowledge what was said. It replies by extending, adjusting, refuting, or replacing.

1 is very difficult and consequently rare.

2 is often taken for 1, and this leads to endless misunderstandings.
