This is something I wrote some time ago, in response to a specific statement. It came up again on the last post, so I thought some clarification was in order. There has been some slight editing fromn the original version.
Van's forum is all about facing up to the flaws in our beliefs, the things that we think are true that may have a cost when things go bad. We are popping the myths that we create about ourselves and our training.
I submit that if you have never had anyone try to gouge your eyes out to escape from a rear naked strangle, you've never tried the technique against a "fully resisting opponent". The first time, I let go of the strangle to protect my eyes. The second time, I knew better. (Edit- but one eye is still blurry almost twenty years later. From that eye gouge or the one four years later? Not sure.)
If you've never cranked on the technique so hard and fast that you heard a "crack" from his throat, you were playing a gentleman's game, politely.
In the time it takes to put someone in a juji gatame and start to yell "Back off or I'll break his arm!" You can easily be kicked in the head three times. Maybe more. I remember the first three pretty well.
If you've feel you've hit a real opponent as hard as you can hit, take the gloves off and try again. I've known people with shattered hands to keep punching, and people with broken skulls to keep fighting.
A fully resisting opponent isn't resisting. He is acting. A pure attack with no thought of defense. He's not resisting your technique, he's trying to beat you so badly, so quickly, that you can't USE a technique. (Edit- I was thinking of the predator ambush when I wrote this.)
I avoid the threads on "Uechi pointy things" (Edit, and what really brought this subject up- someone was claiming that eye gouges and throat spears weren't allowed in his particular brand of ultimate, anything goes, cage fighting because they either didn't work or were too hard to execute.) because I don't know enough about Uechi to contribute. But I have once used a spear hand to the throat. It was easy. It didn't require me to practice magic or have faith in untested complex precision techniques. It left a man who outweighed me by over a hundred pounds on his knees trying to scream and making no sound. That image still bothers me.
Train hard. Hard rolling is fun and good for you and good training. But don't pretend that either you or the other person is going all-out. You want to use the same partner tomorrow and so does he. And don't pretend that dangerous techniques are difficult or complex. You don't avoid them because they're difficult to make work, you avoid them because you need to recycle training partners.
