There you go. That's what I meant. I asked about that from the beginning and people like k-man went ape **** on me. All they had to do is tell me about deai.
If I had heard of 'deai' I would have been the first to let you know. Certainly in our Aikido we have nothing along those lines. However, in karate we have 'sensen no sen' which means to attack when your opponent's intent to attack is first perceived, pre-empting your opponent's attack. Himura Kenshin's description of deai seems pretty much the same. But we don't train it as such. It develops with your overall development as a martial artist.
(And, for what it is worth, this is ape ***t :tantrum: and this is respect :asian: )
The reason I ask about it in regards to Aikido is because it's an overwhelmingly defensive art. It's probably the least aggressive method in the world, so that leaves relying quite heavily on response, and more specifically, reducing the time period between the moment an attack is launched and the moment you react. I would imagine that if the response time is lacking, the Aikidoka could get demolished by an aggressive and quick fighter from more offensive minded methods, like Krav Maga, Muay Thai, Taekwondo and MMA, to name a few.
Not that an Aikidoka would have a reason to fight them in the first place. I'm just speaking theoretically.
