These days I have seen many propose that the sequences that directly corresponds to Karate Kata are the only ones that you might find viable applications from. The unique ones are just there as "filling". I disagree to this point and I do believe that all Taekwondo forms can be found to have viable applications it is just up to us to find them. Yes I see the point that these applications might not have been inserted in the forms originally as the knowledge of the originators of Taegeuk series is greatly debated, but that does not change the fact that the forms are based on movements found throughout other older/traditional forms. Many pioneers of reverse engineering of Karate forms (E.g. Iain Abernethy) explains that each movement in Kata (form) has multiple applications. Therefore chances are that eventhough we have new and unique sequences in our forms the "bits" fits together like a puzzle if we try hard enough. It is just a matter of chosing the right application for each of the techniques so that it all makes sense together.
Simon John O`Neill has allready done this and published a book on the Taegeuk series called "The Taegeuk Cipher". Here I presents the Taegeuk series as a self defense syllabus on its own. Progressing from Taegeuk 1 Jang to 8 Jang, from early stages of a fight to later stages, from basic applications to advanced applications. He did it so why should not we do it? Or if we are stuck why should we not study his findings?
In this post I have chosen deliberatly a sequence not found in older forms that I am aware of so we can see how new sequences/techniques can be used in practical applications. The sequence consists of two movements: Bitteuro Bakkat Sonnal Makki (twisting outwars knife hand block) followed by the roundhouse kick (not found in older Karate forms). This will be step number 5/6 in the form.
In more "conservative" styles of Kukki Taekwondo the roundhouse in Taegeuk Yuk (6) Jang is delivered in "a bigger circular movement" than what is done today. Also the impact point is the ball of the foot (Ap Chuk) not the instep (Baldeung). In competition both are allowed BUT the competition rules clearly states that the instep is preferred by judges (so in reality if you compete you use the more modern competition style roundhouse and not the traditional one). My teacher tries to hold on to the traditional style roundhouse kick in the form as we practise the competition format outside of the form to a great degree anyway. In todays application I have taken the "traditional" delivery of the roundhouse into consideration.
So after the initial stages of the "fight" is over there is usually some sort of grappling involved. Lets presume that the preemptive strike has failed, the initial striking has failed and the opponent has secured a grip on you to try to hinder your ability to strike (see below)
As we do the technique twice in the form we can attribute the knee strike application to one of them and the roundhouse kick to the other so we have the form serve as a mnemonic devise for our applications wich is one of the original intents of martial forms anyway.
The sequence is simple, effective and works well within Taekwondo`s preferred strategy. More importantly it shows that eventhough the Taegeuk series contain sequences that are not found in older form sets the sequences can still be found to have viable combative interpretations.
With that I wish you all happy training:-)
