It is notthe technique of moving quickly to put out a normal throw, which is covered under ‘kara throw’.
A moving throw is a throw that puts out a hitbox while or after moving some distance.
Straightforward to figure out; however, even when as close as possible, unless the startup can be turned into 1 frame, they basically cannot be included inside combos.
Depending on the move, it may have super armor while moving, but in general, the movement is a thrust that is defenseless against things like jump attacks; opponents accustomed to the move can often avoid it once they see it.
You can use it as a surprise attack, but it’s difficult if you aren’t accustomed to the move, and it can easily be a “dead man’s move”. Conversely, a beginner who can’t see it coming will often take it an obtuse number of times.
