Re: "Irimi" by Ellis Amdur
There was a time when it was highly regarded to use a strategy called 'aiuchi' that entailed mutual striking or striking at the same time on the same line and if you died at the same time your opponent did it was thought to be very auspicious. Sometime later some smart fellow figured out 'ainuke' which meant striking at the same time while evading, getting off-line, and killing the other guy while you survive... I've kinda always preferred that survival stuff myself. However, you do not need to get off line to survive and be successful. Entering (irimi) with an unexpected change in the timing so that you get to the target at the right time to cut before being cut is quite possible. Sen sen no sen timing is very useful for this strategy but difficult to do, sen no sen can also be done and be successful, still without getting off line. Getting off-line is great if that's fits the situation and solves the problem. Irimi can be done while seeming to go backwards or away from the target. A skillful person can touch, connect, strike, cut, etc. in many ways that are very difficult to read whether they're on-line, off-line, forward, backward, straight or turning as they go from toimaai to uchimaai.
