Hello all, this is my first post. First of all I live in Malta and have a 7yr old son who has been practicing Kyokushin for almost 2yrs now. he has taken part in 2 tournaments so far, one in Hungary and one here in Malta. He did good in both tournaments!! A few days after the second tournament we received some really bad info from Hungary about his sempai (he is Hungarian). The people that sent the info are well known marital artists and wrote that the sempai is not a black belt, does not have a license to teach and has joined and then left many organizations . Should I let my son keep on training with him or should I search for another dojo. There are no other Kyokushin dojos here in Malta but he can start either Spirit Combat or karate. Another thing, my son has achieved a yellow belt, is this valid since his sempai does not have a license to teach? I would appreciate any opinions that you may have. Thanks
