I stand corrected. I knew that they started with Karate Kata. I had made the assumption that they were Shotokan Karate Kata, since both Choi and Lee trained under and earned rank from Funakoshi, in Shotokan Karate. However, you are correct... the Kata they started with were from Shorin or Shorei.2. The first TK-D forms can be found in General Choi's 1965 book along with the Shorin and Shore forms they were built upon. The similarities are undeniable but to say they were Shotokan (not Shorin or Shorei) is an oversimplification 0
I learned something new....
