He then strangled me. (sidenote: is this a legal move?)
Yep.
I don't think anyone had taught him it! It definitely is not nice, one of the reasons why I thought it was not a legal move.
Most of jiu-jitsu is not "nice" moves. You're training to break people's limbs and choke them unconscious. That's why tapping early and often is so important.
From your description, the kid was doing the classic Hollywood-style choke just wrapping both hands around your neck and leaning his weight on you? The reason that's not taught is that it's much less effective and much easier to escape than a technical jiu-jitsu choke.
kind of made me wonder if I've even learned anything in the 2 months! Maybe I need to start going twice a week.
It's hard to progress very quickly going to classes only once per week. Also, 2 months is not very long.
That's really unlikely to be an actual seizure. That sort of random muscle twitching is quite common when people pass out (or are choked out).
Agreed. I've seen that multiple times.
I'm 34 years old and have been attending class for about 2 months now so I didn't want to try too hard. This attitude led to him (impressively) getting me in a full mount with his legs pinning my shoulders so his arms were free and mine weren't
You just leaned what many martial artists never learn.
There are no lies on the mat.
What's that mean? Spent 2 minutes re-reading this and came up with nothing. But I feel like I should be offended haha
It means you've had a chance to learn the important distinction between what your ego would like to tell you and the cold truth of reality. You thought a little kid couldn't do anything to you and you got choked unconscious as a result. Now imagine it was someone your own size, with actual experience and training, using a proper technical choke which is 10 times as effective as what the kid did to you.
but I think the result was more of a combination of luck
As Renzo Gracie says, the more I train, the luckier I get.
This wasn't a random street encounter where someone cold-cocked you just as your turned to look at a car crash and simultaneously tripped on a pothole. This was a controlled environment on a flat surface with an agreed upon start point. You lost because you underestimated your opponent and then didn't have the skillset to escape once that error in judgment got you into a bad place. Both of those are in your power to work on improving.
me being taken by surprise than a question of skill or strength.
I'll agree it's not a question of strength (unless that's a freakishly strong 11 year old). It's definitely a question of skill. With greater skill, you would have been able to avoid getting mounted like that and would have known how to escape if you did get into that position.
Speaking of, do any of you feel that time was excessive? Even if he didn't notice my tapping, surely he could have used common sense there, I was gagging. I don't blame the kid but surely he should know that strangling for that long isn't good, right?
That's what tapping is for. If your partner doesn't tap, he's indicating that he still feels safe.True, an experienced practitioner will recognize a situation where his partner's hands are unable to tap and will be alert for other signals (like your feet tapping), but if the kid has only been to a few classes, he may not recognize that.
Tip for the future: if you are being choked like that, tuck your chin to your chest and pull your shoulders to your ears. That should protect your neck long enough so that you should at least be able to say "tap" verbally.
