When I was in college, I fenced competitively. (I fenced foil, and wasn’t actually very good, but there you have it). Fencers are ranked A (the highest) through E (the lowest), with a U ranking for unranked fencers. You gain your ranking my placing in a sanctioned tournament, and you have to have a certain number of fencers and ranked fencers to determine what place gets what ranking.
In foil, there’s a thing called right-of-way, where the fencer that starts their attack first gets priority on the touch unless the opponent blocks their blade first. The idea is that if someone is attacking you, the proper thing to do is deflect their attack instead of going for a suicide strike. (Epee is different - whoever hits first gets it). Foil also has a concept of off-target - your touch only counts if you hit someone in the torso. Hitting them in the arm or leg is “off-target” and ends the action. There are electronic scoring mechanisms to determine if a touch was on-target or off-target - a white light for off, and colored lights for on-target for each player.
So, for example, if the right fencer starts their attack, and the left fencer attacks back without blocking, and both colored lights go off, the right fencer gets the point. If the right fencer attacks, the left fencer attacks back without blocking, and the left fencer’s colored light goes off but the right fencers white light goes off (indicating off-target), no touch is awarded and play resumes. BUT, if the right fencer attacks, the left fencer responds without blocking, and ONLY the left fencer’s colored light goes off (if the right fencer misses entirely), THEN will the left fencer get a point.
I say all this because I was once fencing as an unranked fencer in the semi-finals of a tournament against a C-ranked fencer (who should have destroyed me but was getting cocky). If I had won, I would had gotten my first ranking regardless of the final. If I lost the match, nothing for me. The match was progressing and I was actually holding my own, leading at one point. Then for one touch, the other fencer started first, and I stupidly responded without blocking. He hit off-target and I hit on-target. His white light went off, indicating no touch for either fencer. But the ref only saw the colored light for me and signaled a point for me.
Cue an eruption of angry screaming from the other fencer that there was a white light. Cue restrained but also upset yelling from the ref. Cue every fencer, judge, and spectator stopping to see what the heck was going on (the other semi-final match was in a break). It was uncomfortable, but I had seen both lights just as well as the other fencer. So when they both took a breath to keep screaming, I interjected “excuse me, ref, the white light did go off”.
The ref thanked me for my honesty and called the off-target. I lost that match 15-13. Never did earn that ranking. But I also never regretted doing the right thing.
