In the world of competitive aikido we find shomen ate being used often. I recognize that opinions vary about sport, and technique in the world of Tomiki Aikido. But I too am entitled to an opinion also.
IMHO - It isn't shomen ate if....
1. Tori drives uke back with such force you chase them across the mat. This violates the aikido principles of non resistance and indeed the technique becomes just a crude drive just piling on force.
2. Tori falls over because he is adding so much thrust that he cannot keep balanced when uke falls.
3. Tori uses more energy than uke to make the throw work.
Yes I understand these guys play a game. They are probably good at it. I probably would love to train with all these guys. However I understand why aikido people say Tomiki aikido is not aikido, when you see examples like this. I don't think these guys are doing bad martial arts, or bad sports. I do believe that they are missing some critical ideas about what aikido is supposed to be. Again this is in my humble opinion, and I honestly mean no disrespect to the artists in the following videos. Thankfully the world is big enough we can all play however the heck we want. I just wouldn't call these shomen ate, or aiki technique for that matter.
