However, I still think I should take the center before attacking, including while executing the debana-men or the debana-kote. My shinai sometimes wiggles too much without fighting for the center. I should focus more on it.
One time I got hit on the do while I raised the shiani overhead in order to scare my opponent (Katsugi-waza). However, he didn't fall in to the trap but quickly executed a men-kaeshi-do. Next time when I use this technique I have to choose the right moment. When the opponent has an offensive mindset, it is dangerous. However, if he is defensive, then usually it works.
