First, ATC congratulations to your son for his accomplishments. The power and technique are truly awesome.
Now, I am going to be the bad guy on the thread and ask that it be taken as a discussion of issues and not a personal attack on ATC or his son.
While a lot of people applaud watching the other kid go down or as one commenter calls it "exploiting the rules", I look at it a bit different.
Sure there are differences between those who focus on WTF sparring and those who claim to be pure self defense and there are certainly differences in the way you conduct yourself in a self defense situation and in a sparring match. In a self defense situation, kick as hard as you can, do whatever it takes, knock your opponent out, there are no rules but survival. No problem there.
In WTF/USAT and other types of sparring there are rules. When you join an organization and sign up for a tournament you agree to be bound by those rules. I would also assume that when one trains they would be familiar with the rules of the tournament that they are going to attend and plan to abide by them and that their coaches would assist them in doing so.
Having said that, you note that your son was penalized at least once in each of four matches for the same infraction. You are pointing out that your son broke the same rule at least 4 times in the same tournament? How many times? 6? 8? 10? It also seems that you are ok with this?
I am trying to understand, do people consider this to be exploiting the rules or gaming the system to their benefit, or cheating? You note that your son kicks harder in practice so he has toned it down some, so he, and I would assume his instructor, are aware of the rules and the fact that he needs to control his kicks. Even though they are aware, still he gets penalized so much? Is he kicking too hard, violating the rules and attempting to hurt another kid on purpose? with your blessing? with his instructor's blessing? or does he need more practice and to learn more control?
I have seen 12 year olds at other tournaments disqualified for uncontrolled or overly aggressive kicks. I would think that in an instance where a competitor repeatedly in every match commits the same penalty and risks injuring another competitor on purpose(?) that it would not be too harsh to remove the competitor from the match.
The weekend after the junior olympics my daughter was at a tournament in LA. She has been practicing head-shots in anticipation of next year, but the rules do not allow them for her this year. During her match, her kicks progressivey got higher. When she reached the top of her opponent's hogu, I was yelling from the sidelines for her to keep her kicks down. Why? Because I didn't want to see the other girl get hurt. Because I didn't want to see my daughter get a penalty. Because I want my daughter to follow the rules. If she ever purposely went into a match with the intent to break a rule, especially a safety rule, or if she broke the same rule repeatedly, I would remove her from the tournament myself. I believe her master would step in and remove her if I wasn't there. I would have to seriously consider whether or not she could compete again and there would be a good chance that her master would ban her from his school.
I know there are people who will do whatever it takes and break any rule as long as their kid wins. A lady from my daughter's school signed her daughter up in a lower age group since she "wasn't ready" to fight kids her own age. I have a problem and point it out and denounce anyone from our school who does this and would really have a problem if any kid from our school was repeatedly breaking safety rules for an advantage.
So, what do people think? OK to repeatedly break sparring safety rules at a tournament and lose a point or two each match to gain a psychological edge over the opponent? Or better to teach kids respect for rules and be safe?
