We have a student at our dojo who is turning out to be a problem. He has been coming to our dojo for over a year and is not really integrating well to our dojo. He is a low level student from another dojo ( or several as he states) and is quite egotistical about his technique. This guy states he has a couple thousand hours of training (5th kyu shihan anyone!!) yet has not tested to reflect this and it definitely does not show on his technique. When he works out with sempai, he will not take any tips on doing the technique(Myself included) and ignore any suggestions. During the initial movement he never breaks my balance ( I am not holding overtly hard either) then "makes up" some strange movement which is something Sensei did not teach. He then proceeds to take his frustration on not being able to do the waza by using a lot of strength to do it. When he puts a pin on you, you get the feeling like he is trying to "show" you something and the feeling transmitted does not "feel" good. This guy in turn falls before you throw him and taps before you can do a pin. I get a feeling of anger or some sort of passive aggressive issues going on.This guy cannot do basic technique very well and he really thinks he is very good. When ever I work out with this guy I don't know whether to laugh or be scared as he could be dangerous.
This "gentleman" has had several altercations with his sempai already. One even coming almost to blows. I warned my Sensei about several time about this guy unto which they said try to "Be harmonious" on the mat and try and talk to this guy off the mat. I am kind annoyed that Sensei is not seeing this guy is a problem. So far he tries to avoid practicing with all of his sempai and only practices with lower ranked people. What makes it worse is he is extremely socially awkward and does not really hang out with anyone at the dojo. How am I supposed to deal with guy?
