When fighting with Yi-Chen (5th Dan), I had a big problem being able to hit him, which had happened also with some other people before. When he steped in to chikma (close distance), he turned his shinai pointing to his right, in sort of a half-blocking position. I knew I could not reach his men because he can block and even do a kaeshi-do. Kote was also protected because of the angle of his shinai. The only target opened was do, which was hard to hit also because the distance was very close. But I did get his do once.
On the good side, I started to analyze more and more the opponent's movements, and try to develop a strategy against them.
I need to make my attacks more explosive.
