Thanks for posting!
I had a discussion about this with a guy who taught kids.
Kids can have huge variations in strength and they don't know they are doing anything wrong when they do something natural.
He had to teach kids not to slam all the time. But he tried to find ways to make closer guard work so they could use it in self defense.
What he ended up teaching was two responses to the slam. Usually kids would get lifted when they had an over hook, so he taught them to put their feet down and stand up, like a technical standup.
He also taught them to go to feet on hips if the other guy postured up.
The rule they played with, while no slamming, was that you won if you could pick another kid up without hurting them.
So they got creative with the lifts (and thought it was really fun).
The ultimate move from closed guard was to hug the other kid over the legs so they can't put their feet down or open guard. Then they could just pick them up.
Didn't really seem to be an answer for it. I guess you could try to hit a Kimora really quick, but with the power advantage slammers have, that's not likely.
As I read the situation with the kids training, it really shows that closed guard is redundant, use less and plain dangerous to the point that the coach had to created specific drills to avoid slams.
if the person is on his knees, closed guard can be an option.
However, as soonest he stands up, you must relinsquish the closed gaurd and transition to an open guard.
if he does not control one of your sleeve, just open your legs and hit a double ankle sweep, balloon sweep,
If he controls one sleeve, switch to de la riva or just a simple tripod sweep/gaurd if DLR is too advanced.
Now, I have had this conversation with other coaches and they do not agree with me.
Basically for me, do NOT jump guard or ever let your opponent lift you up and you still insist in playing close guard.
I will allow you to pull guard. Nothing wrong with that. A little bit disapointing as we have 4 Judo classes and 2 BJJ classes per week for only $20.
Wish people were willing to do more Tachi Waza as we offer rounds of stand up sparring at every BJJ classes.
I understand that some people train as a sport BUT this is not what I want in my club.
I will gladly re direct a student to more sport oriented gym if he insists on doing that style of BJJ (ie do NOT jump guard or ever let your opponent lift you up and you still insist in playing close guard.).
Strangely, I do not teach BJJ for self defense or even train with strikes BUT it is one of those things that I can dictate in my club as long as I am one of the teachers.
It is kind of weird as I teach and encourage student to do sport BJJ.
Maybe later, when I retire from teaching they can do whatever.
Actually a funny anecdote is one day I would like to teach and train student by never teaching the close guard.
I met a Korean BJJ player and he did not know what was closed guard.
It was amazing. Just butterly, X gaurd, single X and whatever but he could not perform a closed guard to save his own life.
he was a white belt at the time and it was just freaking awesome.
