I was doing kata today and I realized that the opening move in Seuinchin (middle-body block, two arms), the X-block in the opening of Chinto, and the double-overhead block in Seisan (and also Chinto) are all the same block, just variations on a theme. However, I could be imagining things. This is with regard to Isshin-Ryu, BTW.
In Seuinchin, normally I am thinking about defending against a double-handed collar grab by my opponent. But while doing it, I realized I could be blocking a straight punch to the face if I use the 'crossover' while coming up as if it were the same as the X-block in the opening move of Chinto. And I've been shown several times that the double-overhead block in Seisan also crosses the hands subtly and can be used the same way; to block a straight punch to the face.
So what say you Isshin-Ryu and similar ryu karateka?
