I've been doing martial arts for about 7 years, the last year being my training in shotokan karate and I've learned many techniques over my studies that are effective but somehow not allowed in kumite. Some are understandable because they are not of the style being taught but others for example; palm strikes, ridge hands, shutos, and koken are not only not allow but can warrant a disqualification. This troubles me because I feel this is not only unfair but restrictive as well. There is also a gray area about sweeps and throws that I feel will forever go unanswered and any attempt to try using them could lead to scoldings from my sensei. If anyone can shed some light on this or has any personal experience in this matter it'd be helpful. thanks
