Well realistically, if you want to win the sporting match you adapt to the rule set. E.g., if you can move faster with your hands lower, then that may be the way to move.
I understand adapting, but this seems to be more of acceptance that there is no other way. Maybe instead of moving faster, adapt to the speed.
Here's a real-life example:
One of the students I trained in sparring was super-fast for me. He would attack my stomach and then cut an angle. I kept trying to adjust my body fast enough so that I would be facing him. I couldn't make it happen. I was too slow. I just couldn't turn my angle fast enough.
Then I abandon my quest to try to be faster. I dug into the techniques of the form to see if there was an answer there. I tried it and it worked flawlessly. He still landed the shot to my stomach but he never got away after that. The specific tech which made little sense in training with the assumption, but it made a lot of sense in application. It worked so well, that he stopped doing it. Probably my elbow made his ribs feel uncomfortable or maybe the solid bump knocking him off balance did.
The point is that I did have to be faster I just had to adapt to the speed and not exploit the rules.
Maybe a rising block will prevent a kicking leg from landing on the front of the face or on top of the head.
Maybe a lower stance reduces the strike zone and creates a bigger gap for the opponent to cross.
Maybe hands up will shut down attempts to score on the head. My observation is thst adapting to the rules gave birth to yhinks most wouldn’t qualify as TKD or KARATE.
People just have to be careful not to throw out the system for the sake of rules. A lot of what is acceptable in point sparring today was not acceptable when I took karate and would not be considered as valid strike.
