Hello everyone.
Today I took some time to watch a few Kukkiwon taekwondo vids and something seemed different from the way we perform at my school (that teaches Kukkiwon style). It was the hip position at the end of a few movements like down block (are makki) in front stance (ap keubi) - for example, as seen in the 5th movement of taegeuk il hang.
In the school where I practice we perform the hip rotation in that movement in the same direction following the arm that goes down (e.g. if I perform right down block, my hips turn clockwise seen from above). As a result, we finish the movement having the torso completely centered (instead of slighted tilted to the side as it more usually happens to shotokan karate). But in the vid I saw the performer seemed to always finish the position slightly off the center, more like it is usually seen in shotokan.
The way I learned it was that front stance low block usually ends with your torso still somewhat turned, and in Taegeuk 1 you then turn your hips with the punch and end the movement with your shoulders square.
I just checked the KKW video for the form and it looks like that's how it is there, only the guy turns his hips even a little farther than square for the punch. It's a little hard to tell though, because of the camera angle.
