Here's my interpretation of the first two moves of Geecho Hyung Il Bu (or Tae Guk Il Chang, I suppose). I've been experimenting with developing progressively live drills to practice it. The progression goes something like this: 1) the form. 2) One-step sparring. 3) Practicing the two strikes on the heavy bag to develop the proper body mechanics. 4) Sparring drill wherein one person throws jabs and crosses at 50% speed and the other seeks to use the combination as a counter. Drill ends when the designated partner uses the combination defensively 10 times. 5) Live sparring, all strikes allowed, but points are only awarded for using the combination; the first partner to use the combination 10 times, either offensively or defensively, wins.
Any feedback on that progression or on my interpretation of the form is welcome. I can imagine, for example, that the progression might need to be modified if it were to be used to practice self-protection rather than fighting. I'd also be curious to hear interpretations from clinch range.
