Rules Blog: Using Video Replay

The introduction of video replay technology at all levels of fencing has been unquestionably beneficial to the sport. Particularly in priority weapons, where the referee and the judging of touches is such a crucial part of the action, video replay provides both the ability to prevent refereeing errors from unduly affecting the outcome as well as valuable learning opportunities for referees developing their abilities at all levels.

USA Fencing referees should be aware of the basics of using video replay: The challenge system, required reviews at 14-14 or 44-44 or in overtime, etc. This edition of the Rules Blog instead addresses some common questions and best practices for using video replay.

Decision-making Responsiblity

The important thing to remember is that final decision-making responsibility for the bout rests with the referee on the strip. In fact, per article t.42, the rule book describes the “video referee” as a “video consultant”–and a consultant is exactly what they are. The job of the video consultant is to lend their opinion and expertise to the proceedings, but the ultimate responsibility for what takes place during a bout or match belongs to the referee on the strip. There is no rule, for example, that mandates that a decision be “thrown out” if the referee and consultant disagree.

That being said: Any referee, regardless of level, should approach a video appeal with an open mind. We use video replay and the consultant system to help us get things right and to help us learn. It’s a rare opportunity for us, as fencing referees, to work as a team. I encourage the on-strip referee to make the best possible use of their teammate’s help, especially if the video consultant is more experienced.

In addition, only the referee and the video consultant are to be involved in any decision regarding the bout. No one else–including the assigner or head referee, the camera operator, other officials, etc.–may contribute to the opinion. No other personnel should be inside the video replay enclosure during the bout.

Being a Good Video Consultant

To be most effective as a video consultant, the best starting point is to watch the bout live as if they were refereeing themselves, and have an opinion on each action. Watching the bout live is actually stipulated in the rules (per article t.37), and the consultant’s opinion or “feeling” for the live action can be just as helpful to the final decision as the video itself. The video representation of a bout isn’t perfect, as there is no sound and the image becomes “flattened” and two-dimensional. It’s often much harder to get a definitive feeling for an action if you’re watching it for the first time on video.

When an appeal happens, I encourage the video consultant to give their opinion definitively: “I think the action is [x].” Video consultants shouldn’t be shy with their opinions, particularly more junior consultants–learning to be a good consultant also takes practice. Again, the consultant’s opinion is another source of help and input for the on-strip referee. However, I urge both referees involved in a video bout to keep the discussion calm, quiet, and rational.

In addition, both referees should treat the discussion as confidential, and as information that doesn’t leave the area of the table for the duration of the bout. The video consultant should ensure that no other parties enter the video area during the bout–not the head referee or assigner for the event, support staff such as referee evaluators, or unassigned referee colleagues. The one exception is a technician for the video system if there are technical problems with the camera or replay system. We must take care to avoid even the appearance of undue or outside influence in replay decisions. It goes without saying that the fencers, coaches, and spectators, are not to be involved, and it is the video consultant’s responsibility to protect the video image from outside parties (such as coaches) that might seek to interfere or inject themselves into the decision-making process.

Video Replay Speeds and Action Usage

While video is helpful, take care to use it to its best advantage by understanding the system’s limitations.

In right-of-way weapons, the referees determine which fencer’s action takes priority by using an intuitive understanding of how those actions fit into convention. Fencing takes place in real time, and slow-speed analysis or frame-by-frame parsing can often introduce artificial distortion into the process. For this reason, I recommend watching priority actions such as attack/counterattack at a minimum of 80% speed.

The video system also isn’t ideal for blade actions, such as determining when and where beats or parries occurred (such as “were there two blade contacts or just one?”). The image “flattens” and loses its depth; on video, the best you’ll often do is to see a potential for blades to intersect but rarely definitive proof of contact. The absence of sound also contributes to this issue. For appeals on these cases, it’s very important for the video consultant to watch the action live and have a second opinion to aid in the decision.

For purely chronological cases, particularly in epee, feel free to use the lowest replay speed available. These are questions such as “did the action arrive before the fencer left the strip?” or “was the scoring apparatus triggered when the fencer hit the floor?” In this case, slow speed analysis (10%) or frame-by-frame parsing can help the referee and consultant be definitive in their decision-making.

Failure of the Replay Apparatus

Occasionally, owing to a technical error in the software or a manual error on the part of the camera operator, there might be actions that weren’t recorded on video. Unfortunately, the rule book does not cover this specific situation, but the FIE Handbook of Regulations and guidance from FIE Arbitrage can provide us with a standard practice:

In the case of video failure, the on-strip referee has sole responsibility for the final decision. If they have already given a decision before a video appeal, that decision stands. However, the fencer making the appeal retains their challenge.

In such a case, do not charge the fencer for a failed appeal, because the appeal was prevented by the failure of the video system. The on-strip referee should clearly explain this decision (including the decision not to charge a challenge) to both fencers, so that they’re aware of the replay situation.

Lastly, should a video failure occur, remember that it’s usually counterproductive for either the on-strip referee or the video consultant to immediately announce to the entire room that the replay apparatus has failed. Doing so only encourages outside interference in the subsequent decision from fencers, coaches, and spectators. When possible, as mentioned earlier, keep the discussion calm, quiet, and confidential.

Hopefully, this advice can help you and your referee partners use video to its greatest advantage, and help make the sport better for everybody.

Best of luck out there!

Rules Blog: 2017-2018 NAC Pre-Season Information

 Rules Application, Rules Blog  Comments Off on Rules Blog: 2017-2018 NAC Pre-Season Information
Oct 032017
 

As the 2017-2018 season gets underway with the October NAC in Anaheim, I’d like to cover some points of emphasis:

First, no rule changes, major or minor, for the upcoming season. As you may have heard, the FIE has officially shelved their rules experiment with non-combativity, making moot any question of adopting the proposal at any time in the United States. No other major rules changes have been proposed or adopted for 2017-18.

Armorers at NACs have been instructed to inspect any elastic strap-style safety devices on masks. At the direction of US SEMI, the armory staff at each NAC this season will begin inspecting the integrity of the elastic strap on fencing masks; this includes the horizontal safety strap on masks with the strap-and-metal-tongue design, and the straps webbing on Comfort Fit Leon Paul masks. The armorers are to ensure that the strap(s) stretches (the elastic has not been worn out) and is in satisfactory condition. From US SEMI:

“To check, give the strap a gentle tug. If there is no stretch or if it’s just too big to hold the mask in place, reject the mask and advise the strap be repaired. Do not fail or confiscate the mask. It is acceptable to stitch up a band to make it shorter as long as it can still stretch to hold reasonably well to the back of the head; otherwise, it must be replaced.

We understand there is some judgement involved in the terms “decent condition” and “reasonably well”. Therefore, for this season, it is advisable to be a bit more lenient in accepting or rejecting masks. For questionable cases, point out the problem and advise the fencer to get the strap repaired soon.”

Solder lugs cannot be used to secure weapon wires to the socket inside the guard. US SEMI was asked to make a recommendation on this practice, which some armorers have been using when assembling weapons. The solder lug and shrink-tubing obscures the connection of the wire to the socket. When wiring your weapons, please secure the wire in the typical way, i.e. wrapping the wire around the socket post and securing it with the bolt and washer.

Referees should be aware that this method of wiring the weapon has been deemed unacceptable at the direction of US SEMI, and apply the rules (specifically t.45) associated with non-conforming equipment.

Thanks, and good luck out there,

Rules Blog: The Field of Play

As you may be aware, USA Fencing uses a variety of pistes at our North American Cup tournaments, with some variance in size and markings. Because of this variance, there has been some confusion in the past as to what parts of a given piste are considered “in-bounds”, particularly with regard to the pistes we use for bouts on video replay (typically beginning in the round of 16 through the semi-finals).

Specifically, I’m referring to pistes supplied by Leon Paul or Absolute Fencing that look like these:

There has been some question as to whether or not the colored border along the sides of these pistes is considered in-bounds or out-of-bounds. Members of the Rules Committee who are active international referees have raised this question throughout the season with members of FIE Arbitrage, and the interpretation at the FIE level has been consistent: the entirety of the metal surface of the piste, including the colored areas, is considered “in-bounds”.

The rationale provided by FIE Arbitrage is that fencers often determine their location on the piste (whether on or off with respect to the lateral boundary) via tactile means (e.g. by feeling with their feet). If we enforce the edge of the strip as the painted surface, referees are compelled to cause numerous counter-intuitive and disruptive stoppages in the bout. These stoppages harm the fencing and make judgement more difficult. In addition, a large number of standard grounded pistes lack the side markings and are treated as entirely in-bounds, and fencers often struggle (or fail to) adapt to the change in markings.

This image from the Budapest Epee Grand Prix is an example of senior international epee fencers and officials treating the entire piste surface as in-bounds:

The Referees’ Commission is therefore directing American referees to adopt the same interpretation at our North American Cups and at the upcoming Summer Nationals.

Good luck out there!

Rules Blog: Conflicts of Interest

 Rules Blog  Comments Off on Rules Blog: Conflicts of Interest
May 122017
 

This edition of the Rules Blog focuses on a question from member Richard Lee, about avoiding conflicts of interest while refereeing:

“I fence competitively (and so does my son), and I am a member of a Club, so I would like to know when I can and when I can’t referee a particular (or any) bout in a USA Fencing-sanctioned Tournament (I suppose it would be more lenient in non-sanctioned bouts).

1. I am sure I can’t referee a bout/pool that I, my son or a Club mate is fencing in. Similarly, I would imagine I cannot referee a Tournament that me or my son is competing in, regardless of me avoiding refereeing any of my son’s bouts (perhaps I am wrong?). However, can I referee a Tournament that includes a fencer (not me or my son) from my Club, as long as I do not referee any of his/her particular bout/pool? I may be wrong in some of my assumptions above, so I would love to know the proper rules on this.

2. Also, is there a restriction on refereeing a bout involving a fencer who I personally know, but is not a relative or a Club mate (or other fiduciary/official relationship)? Since I fence, and my son fences, I certainly have gotten to know (to varying degrees) a lot of the fencers (both Youth and Open fencers). Obviously, I cannot be biased and must be strictly objective, but I have socialized/gotten to know a lot of fencers in my Region.

I very much appreciate your guidance. Thank you!”

And the answer, from the Rules Committee:

Hi Richard,

These are good questions. Avoiding conflicts of interest is extremely important for referees, and USA Fencing referees make it a point of emphasis to make sure to avoid conflicts or even the appearance thereof. The FIE Code of Ethics, in Statutes Chapter 12 states that:

“[Referees] must avoid accepting an assignment to referee any match in which they have a perceived
or actual “Conflict of Interest” with any participant. Conflict of Interest shall mean any
situation where a conflict exists between the duties and the private interests of a referee or
judge, in which s/he has direct or indirect private interests that affect, might affect or seem
to affect the performance of, in an incorrect way, the referee’s or judge’s responsibilities
and duties as a referee or judge.”

Keep in mind, however, that “fencing is a small town.” As you referee in your local area, or even nationally or internationally, you’ll get to know the other members of the fencing community and likely become friends with them. It’s simply impossible to avoid refereeing someone that you know. In that case, we define “relationships” as being familial or fiduciary (such as affiliation with a fencing club).

1. Conflicts depend on the level of the tournament. We avoid conflicts based on personal relationships (such as family), club affiliation (teammates), and geography. I’ll take these in order:

Personal Relationships: You should recuse yourself from any bouts or pools that involve a family member, spouse, or significant other (any romantic relationship). That means you are correct in that you should not referee any bout or pool in which your son is fencing, at any level. You may, however, referee a tournament that your son (or a person with another such relationship) is fencing in, provided you aren’t involved with any of that fencer’s bouts or pools. A coach/student relationship is also a personal relationship in this context, whether past or present.

Teammates/Club Affiliation: You should recuse yourself from any bouts that involve your teammates–however, you can referee pools in which you have teammates/club members, provided you don’t work the actual bouts. In such cases, you should ask for help from another referee to handle those bouts that involve your teammates.

Geography: We avoid geographic conflicts only at the National or International level. At the National level, you should avoid refereeing fencers that come from the same division as you do. At the International level, you should avoid refereeing fencers from your home country. Bear in mind that at local tournaments, everyone will be from the same one or two local divisions, so these conflicts are not considered at that level.

2. There is no restriction on refereeing fencers that you know personally if there is no familial or fiduciary relationship. Fencing is a small town and you’ll quickly find that you get to know everybody. Use your judgement when recusing yourself; if you had a past personal relationship with a fencer (such as a romantic relationship), or coached a fencer personally, or had any other kind of personal relationship that would make you personally uncomfortable with your ability to be impartial, you can recuse yourself and you’ll find the community to be understanding.

Hope this helps! Thanks for bringing up such an important question.

Best of luck out there!

Rules Blog: On Corps-a-corps to Avoid a Touch

 Rules Blog  Comments Off on Rules Blog: On Corps-a-corps to Avoid a Touch
Jan 102017
 

We’re all aware that when two fencers are in physical contact, we as referees need to stop the bout in accordance with rule t.20.1. When fencers are engaged at close quarters, such contact is relatively common and often accidental.

It’s important to keep in mind, however, that the contact may fall under the situations outlined under article t.20.2: “In all three weapons it is forbidden for a fencer to cause corps à corps intentionally to avoid being touched, or to jostle the opponent.” This contact merits a first group penalty: A yellow card at first offense, and a red for subsequent offenses.

So how do we tell the difference between an accidental or incidental corps-a-corps and a fencer intentionally making contact to avoid a touch? Like a lot of other decisions we make, this is a judgement call and is dependent upon the individual fencing situation. The rulebook doesn’t codify when to apply incidental corps-a-corps (a halt) versus corps-a-corps to avoid a touch (a Group 1 penalty), but the action can give us some context clues. These can include fencer movement and the priority of the action.

Fencer Movement

Generally speaking, a fencer cannot cause corps-a-corps (to avoid a touch or otherwise) if they’re stationary. A fencer holding still will almost always be subject to the other fencer’s corps-a-corps. If two competitors make contact and one of them isn’t moving, the stationary fencer most likely did not cause the contact. That doesn’t necessarily mean that the fencer causing the contact should be penalized, but it can help you make your decision based on other factors (like the priority of the action).

(A fencer can cause corps-a-corps without moving their feet by “pushing off” with either the armed or unarmed arm, or by leaning their torso, but in neither of those cases is the fencer considered “stationary”–they’re moving in some sense.)

The Priority of the Action

With movement established, another important clue as to whether or not a fencer has made contact to avoid a touch is the priority of the action during which the corps-a-corps took place.

The most common reason for a fencer to cause corps-a-corps to avoid a touch is because they are at a disadvantage in the fencing phrase: their attack has just been parried, or they made an action on the target that missed. Knowing that their opponent’s next action will take priority over theirs, such a fencer may attempt to force a halt by causing body contact. The penalty in t.20.2 is specifically designed to prevent a fencer from doing this.

Both the context of the larger phrase and the individual fencer’s action can give you information to help you apply a penalty (or not). If a fencer is collapsing the distance toward their stationary opponent, but their action has priority (they’ve just parried, or they started an attack first) and they’re trying to bring the tip to the target, then the corps-a-corps is likely accidental; they’re not trying to avoid a touch, they’re trying to score one. Causing corps-a-corps in such a situation confers no advantage to them, and as a matter of fact, puts their action at risk. In such a situation, you should not penalize a fencer under t.20.2.

While epee doesn’t use priority rules for scoring, all actions take time to perform and can confer similar relative advantages and disadvantages. An epee fencer might be parried, with the defender maintaining control over the attacker’s blade. The attacker might then cause body contact to try and create a halt and prevent the defender from taking advantage.

Intent of the Rule

t.20.2, or corps-a-corps to avoid a touch, has always been an important rule in epee. This season, it has become particularly important in foil. The new penalty for reversing the shoulders makes legal fencing at close quarters in foil somewhat more difficult, and creates an incentive for a fencer who is at a disadvantage in priority to collapse the distance or “crowd” their opponent. Should a fencer in such a situation make body contact, you should penalize them according to t.20.2.

Good luck out there!

Rules Blog: On Passing — What is “Completely Past”?

 Rules Blog  Comments Off on Rules Blog: On Passing — What is “Completely Past”?
Oct 312016
 

Beginning in 2013, the FIE moved to change the wording of rule t.21.3, which stipulates when the referee should call “halt!” when the fencers have passed one another. Specifically, they inserted the phrase “goes completely past” the opponent:

“When a fencer goes completely past his opponent during a bout, the Referee must immediately call ‘Halt!’ and replace the competitors in the positions which they occupied before the passing took place.”

So what do we mean by “completely past”?

We’ve now had a full quadrennial of fencing to gain consensus on what “completely past” means, and based on the experience of our colleagues working abroad, it is this:

Fencers are “completely past” one another if their entire torsos (shoulder to shoulder) no longer overlap.

Basically, if you can see daylight between the fencers’ torsos, they’ve passed.

Intent of the Rule:

The FIE adopted this rule to cut down on a high number of early halts called for passing at close quarters when any part of the fencers’ torsos overlapped. Admittedly, the updated wording has its own ambiguity, but we as a group have had a few years to get used to the change, and the interpretation has coalesced somewhat.

Things to keep in mind:

– Occasionally, you’ll find your own viewpoint offset from the relative center of the fencers as you position yourself to keep the scoring apparatus in your field of view; be aware of this when judging when the fencers have passed.
– You don’t need to factor in the fencers trailing extremities when judging whether or not the fencers have passed one another. This holds true regardless of the situation–either live or on video replay.
– If a fencer being passed makes an immediate riposte started before the opposing fencer is completely past, that riposte is still valid if it lands after the pass has concluded (as stated in t.21.4).

Good luck out there!

Rules Blog – Clarifying the Reversal Rule in Foil

 Rules Application, Rules Blog  Comments Off on Rules Blog – Clarifying the Reversal Rule in Foil
Sep 292016
 

It’s come to our attention here at the Rules Committee that there have been some further questions about our previous post, Interpreting Reversing the Shoulders in Foil. Specifically, there have been some questions about the last section, “pulling back at close distance”.

Some readers have interpreted that section to mean that a backward rotation should be considered legal, even if it results in the shoulders being reversed with respect to the opponent. That’s not the case. Reversing the shoulders with respect to the opponent (where the non-weapon arm is between the two fencers) is always a penalty, regardless of which way a fencer turns.

Here’s an example of an action where the fencer on the left pulls his weapon arm and shoulder back, as opposed to a forward rotation. However, note that relative to his opponent, he has reversed his shoulders and should be penalized according to the rule.


Downloadable Video – Shoulder Reverse

I’d like to stress that this section about pulling back is only relevant when a fencer is being passed on the weapon arm side, and the two fencers’ shoulders remain “squared up” relative to one another. The above video demonstrates a situation in which a fencer rotates backward, but should still be penalized for reversing because of the relationship of the shoulders with respect to the other fencer.

A good rule of thumb to follow: If the non-weapon arm is between the fencers and you ask yourself, “is that possibly covering?” the answer is that they definitely reversed.

I hope this clarifies a few things. Good luck out there.

Rules Blog – Interpreting Reversing the Shoulders in Foil

 Rules Application, Rules Blog  Comments Off on Rules Blog – Interpreting Reversing the Shoulders in Foil
Sep 112016
 
As you might already know, USA Fencing has adopted a rule change from the international fencing governing body (the FIE), in which a foil fencer who brings the shoulder of his/her non-weapon arm forward of their weapon arm shoulder is now subject to a Group 1 penalty (a yellow card). According to the FIE’s proposal to the congress, the rule change is intended to cut down on cases where it isn’t clear if a fencer substituted valid target with their off-weapon arm while reversing their shoulders.

The thing to keep in mind when watching for this penalty is that you need to look for a forward rotation relative to the opponent–a fencer making a move to bring their off-shoulder forward such that it ends up closer to their opponent than the weapon arm shoulder. When both fencers are in front of one another at normal fencing distance, this is pretty easy to spot.

However, there are some cases where a fencer may end up in a position where their off-weapon shoulder is closer to the opponent than the weapon shoulder, but not as a result of that fencer making a forward rotation. These are cases where you should not apply the penalty. Specifically, these are situations when the fencers are passing one another, and situations where a fencer is pulling back at close distance.

Passing

In passing cases, fencers will usually end up with their shoulders reversed in relation to one another, but it’s because their position on the strip has changed–not because either fencer has made a forward rotation. Some examples of passing situations where you should not penalize a fencer for having their shoulders reversed:
  • A fencer who has run or fleched past their opponent; they are not not obligated to turn around once they’ve passed and should not be penalized.
  • A fencer who has been passed by their opponent, who is now behind them, should not be penalized.
  • A fencer who turns to make a riposte on an opponent who is passing them should not be penalized.
It’s important that you differentiate between a fencer who is turning forward relative to a static opponent and a fencer who is turning to track an opponent moving past them. Only the former merits a penalty.

Pulling Back at Close Distance

This is perhaps the trickiest case. You’ll see it happen primarily with opposite-handed fencers (lefty vs. righty) when one fencer closes distance rapidly toward their opponent’s weapon-arm side. If a fencer rotates backward–meaning they pull their front foot and weapon-arm shoulder backward to make a hit on the target as their opponent moves closer to them–they may end up with their shoulders reversed. In many cases their shoulders will not be reversed relative to the target, though the target is still at least partially in front of them relative to the strip. In this case, you should not penalize the fencer who’s rotating and pulling back to make a hit. They aren’t bringing their off-weapon shoulder forward; they’re bringing their weapon arm back, in response to the opponent closing distance.

Intent of the Penalty

The penalty for reversing the shoulders is intended for fencers who reverse forward in order to avoid being hit. Keep that in mind when applying this penalty; we don’t want to create an incentive for fencers to either attempt a pass or collapse the distance in the hopes of getting their opponent penalized for trying to make a hit.

Bear in mind that we want to ensure that the United States’ referees interpret the rule in line with our colleagues in the international community; the Rules Committee will update our information here with observations from American referees that attend competitions around the world as necessary. Best of luck out there!
