What should happen after Fencer X causes incidental corps a corps with Fencer Y and subsequently leaves the side of the strip with both feet?

In the scenario presented, after Fencer X causes incidental corps a corps with Fencer Y and steps off the side of the strip with both feet, the correct course of action is that Fencer Y holds their ground except in instances where it would result in Fencer X being placed behind their end line, and in this case, there is no penalty imposed on Fencer X.

The rationale behind this is based on the rules governing the movement and positioning of fencers on the strip. When incidental contact occurs, it is recognized as an unintentional situation rather than a violation of the rules that would require a penalty. In cases of incidental corps a corps, the referee typically allows the bout to continue without assigning blame, especially if stepping off the strip was not performed in a manner that leads to a tactical advantage.

Fencer Y's ability to hold ground is important, as it allows the bout to maintain its pace and flow without unnecessary interruptions. Furthermore, the exception regarding Fencer Y not holding ground if it would place Fencer X behind their end line ensures that the rules maintain fairness and prevent any potential disadvantage due to positioning on the strip.

In summary, this scenario emphasizes the importance of context in fencing penalties and the application of rules during bouts,
