Yesterday, I was attacked luckily I gave my attacker a few punches to the face. The attacker was twice my size I realized I had my shinai on me but I was in a very tight spot I havent been doing kendo for long only about 2 weeks or so but having a weapon was better then none. I gave him a lot of good blows to his head, which agitated him then he grabbed me and I couldnt do a thing, I bit down on his shoulder until i tasted blood and thats when he let me go and I ran away. I realized later that so far I couldn't do anything in a closed up space. Is there a style I can learn that helps more in closed spaces cause I'm 100% that I will be attacked again and I know it.
Any tips will help, or should I just dump kendo and start mauy thai?
