1. Many Aikido waza make use of a fulcrum. Many simply believe the fulcrum to be an innate reality. However, the fulcrum in most cases is dependent upon the lever for it to act like a fulcrum. The lever itself is equally dependent upon the fulcrum, as it is equally dependent upon its own rigidity and/or its "resistance" to losing its shape as a lever. By this reasoning, whereas a lot of folks think that Aikido waza do not work and/or are difficult to get to work when an uke or an attacker is being resistant, since their body and/or a part of their body is often the lever in an Aikido waza, I would put forth that Aikido waza actually need resistance in the attacker in order to function as designed -- especially in the cases where a fulcrum is used. If you can imagine a see-saw. It has a fulcrum and a lever. The resistance of the lever allows the fulcrum to function -- which together allows the seesaw to see-saw. If by a miracle the lever of the seesaw would turn into a liquid, losing its resistance, the fulcrum would lose its capacity to function, and thus its nature, and nothing would see-saw. What we see when an Aikido waza is thwarted by resistance is not the antithesis of harmony but rather a failure on the part of the practitioner to place the fulcrum of the waza in relation to the resistance of the correct lever, which thus allows it (the fulcrum) to serve its purpose. For the fulcrum and lever to function in harmony with each other, resistance is not only wanted, it is mandatory.
This is VERY interesting. I have been playing around with this myself. I have several students who are doing Sytema as well as Aikido. What I have found is that my technique works just fine inthe sense that when they attack me I can defend myself and control their centers. But I can't use them as ukes when I am teaching Basics because the complete lack of resistance in their ukemi makes it difficult if not impossible to produce a particular technique "at will". In other words, to produce specific Aikido techniques I need Aikido ukemi which is the tension you are talking about.
My current thinking about Aikido technique is that it is all ikkyo. And Ikkyo is simply defined as running a spiral that allows you to rest your body weight on top of your partner when he is out of alignment. If I stay with that idea I have no problem handling the Systema boys but it is difficult to produce many Aikido basic techniques and even then when they happen, they just seem to happen on their own, not due to some intention on my part. If I try to execute a particular technique rather than just keep connection and allow the technique to happen on it own they can escape.
