O'Sullivan sensei did pull me up on my 'flicking' kensen while in chudan last night.
Friday night was tough, not felt that knackered for a long time. Most notable point of the night was when I was fighting Charles who's a club vet. He started to break his cut timing which threw me out completely, I was left wafting my shinai in the air on a number of occasions after failed suriage attempts.
This proves that I focus too much on my opponent's shinai rather than his whole body. I should do my own thing instead of following their sword.
