Re: Aikido vs non-committed attacks?
One of the great things about the practice of Aikido over "sport martial art systems" is that it makes attempts to train things like awareness, outside of "normal fighting conditions". Hopefully, if you're training well, you will be aware of the dangerous "bar" situation, before it gets out of hand, and avoid the jab well before he even thinks about throwing it. All good in theory and hard in real life, I've been caught myself in very similar situations; but that is our goal.
Aikido training is so much more then most of us allow for. It really is a great system! Good luck, and best to you in your training!
