What is the ilgiyae specifically? Ilgiyae is your own technique you have chosen.
Ilgiyae should be chosen this way.
Choose one of technique among those which you have seen and learned in the training. It should be the one which you can do best, which you like most, which you understand best, and which you trust most.
The one that you like most may differ from one that you trust most. In that case choose any. But generally you can trust a technique that you understand, and you can be skill in that technique only with this conviction. You will like one only when you are skilled in it.
Anyway, it is important to choose one. It doesn't matter even if it were not the best choice. Don't be troubled for the sake of the best choice.
When you are beginner you should practice it several million times or more of repetition. So you should be able to subjugate your opponent with it in every situation you can apply it, whenever and wherever.
