The text reads: “When, during an attack with an advance, the attacker stops or hesitates after the first step, and then invites or feints, thus provoking a counterattack, he is in error.”
This is perhaps the most complicated of the incontri. It defines the priority of entering into distance while making an attack. Implicitly, what this is saying is that the attack must be a single uninterrupted action. As long as it meets the other requirements for priority (line, time, and measure), the advancing attack has priority. However, if the advancing fencer pauses upon entering into distance, his attack has ended, and he no longer has priority. Any attack made after this pause is a second, separate attack, for which priority has to be established anew.
