Kihon kumite for the advanced practitioners #3 - Machine gun Kumite against 10 opponents

Asai Karate: 2023 Mumbai seminar
浅井空手: 上級者向け基本一本組手その参・機関銃組手・10人の相手が次々と追い突き:インド・ボンベイ講習会
In this Kihon kumite, you will have 10 -12 opponents lined up in front of you. I used only 3 opponents to demonstrate how to do this Kumite.
The key idea of this Kumite is these attackers will continuously execute the attacking technique (Chudan oizuki here) one after another, as soon as the defender completes block and counter.
If the attackers could execute (timing and distance) correctly, the attacking side would be like a "machine gun".
There are many variations in this kumite method. In this class, I picked the easiest attacking technique, Chudan oizuki 中段追い突き.
Once the students learn how to do this with Chudan oizuki correctly, they can advance to Jodan oizuki 上段追い突き, Mae geri 前蹴り and other techniques.
You can easily guess what kind of accidents Jodan attacks, Mae geri, etc. would cause, if the defenders are not familiar with this kumite pattern.
Here are the rules for the defenders:
The defenders will stand in Shizentai 自然体 position as you do in regular Kihon ippon kumite 基本一本組手.
Do not step straight back when you block. Go either to the diagonally back or to the side.
You must not use the same block and counter combination in succession.
You must not stay at the same position. You need to alternate left and right side shifting.
After each attack, the defender must return to the original position and stand in Shizentai.
The rules for the attackers:
Ten attackers will line up in one line in front of the defender.
Every attacker must assume Zenkutsu dachi 前屈立ち with Gedan barai 下段払い position.
They need to move gradually forward to assume the correct distance from the defender.
The attacks must be done one after another without stopping.
The front leg sides (left and right) must be alternating, so that the attacking sides will change each time.
If you are practicing any type of Kumite with only one opponent, you will never be ready for the real fights outside of dojo or tournament site.
