What is illegal at your club while rolling?And was there are specific reason for it being made illegal?Are there submissions only certain belts(experience) can do?

BJJ,Judo or Submission wrestling I am interested in.

If there is anyone from Gracie Barra schools ? it would also be good to hear what there policy is.

Well, basically for no-gi neck cranks, leg locks (with the exception of heel hooks) and so on are okay, usually for gi we allow them as well. As with everything else you put it on slowly and use common sense; if your partner isn't tapping, maybe he just doesn't realise he's in danger.

White belts using footlocks/leglocks other than the Achilles lock is frowned upon, in my experience. People at that skill level can't be trusted to safely be on the giving or receiving end of those.

Slams are the only thing out of bounds while rolling. Lower body submissions against noobs is looked down upon; but that only applies for the first month or so.

Granted, I have only been training a little while, but at my school, slams, and ANY subs below the waist aren't kosher for us yet. However, I heard for blues and higher, it's best judgment. Nobody is out to hurt anybody after all. :)

No heel hooks. I'm pretty sure slams are illegal too but I do them all the time because I'm an asshole.

Neck cranks and leg subs other than the heel hook are fine. The instructor even encouraged me when I tried an Achilles lock on my first roll.

Anyone have rules against compression locks?

There are no stated rules where I train, but the etiquette seems to be that you abide by the ruleset of the lowest belt. I.e. no kneebars on whitebelts, even if you are a brown.

Everything is open. Dipshits that twist fingers and toes get dealt with.

Douchebaggery is controlled by peer "influence".

I think about the only things that are discouraged at our gym are heel-hooks and kneebars for safety reasons. We don't deal much with leg locks of any sort anyway because they tend to be low-percentage.

Heelhooks and similar locks are banned but they're fine if you clear it with your partner beforehand. Some bastard catch wrestler did a shin lock of some kind on me last night (without clearing leglocks beforehand) as I was RNC'ing him, I might have held the choke a little longer than I needed to after that >_<

Kneebars are avoided but nothing is illiegal. That being said, i play by tourney rules for personal reasons.

I can't ever see throwing on neck cranks during sparring for example. Even if I somehow become ten times tougher/more skilled and fight MMA, what if I'm there twisting a guy's spine and he won't tap? Breaking an arm is one thing, but I can't imagine being prepared to dish out quadraplegia.

On the actual topic of the thread, at my school the lower belts (this means me) are mildly discouraged from using tournament-illegal stuff, but no one complains when I wrist lock finish from the omoplata. The higher belts all merrily bicep slicer and knee bar each other, though now I think of it I've never seen anyone heel hook.

Slams against anyone. Heelhooks against someone unfamiliar with it. Straight leglocks are fine against everyone, compressions are OK as long as you're not being a dick.

Generally techniques are slightly limited against anyone who's a total noob. Our instructor may say arm bars and triangles only. This keeps them from hitting the panic button, and also makes them very aware of the exactly how those techniques can be applied, and how to exercise defense against them.

Once someone gets a little more experienced, it opens up. But if anyone is being a dick with stuff, cranking excessively, or using more dangerous stuff without seeming to acknowledge the risks, then they only get to play with the more experienced folks who work them over thoroughly. Usually this gives them the hint to stop being a dick. If it doesn't, they get a talking to, or just stop showing up.

Pretty much everything is cool at my club, but we still don't slam, heelhook and neck crank eachother all that often.

At our gym were are mostly pretty relaxed about the submissions, but our instructor always tells us that it is your friends you are rolling with and we are here to learn, not to hurt each other.
With that said, neckcranks are greatly discouraged at practice, and only straight kneebar and anclelocks with the ancle in your armpit are the allowed leglocks.

Furthermore, my back has really hurt the last two weeks(the first week I couldn't train), because my elder sisters boyfriend, who is way bigger than me, neckcranked me at BJJ-practice.
He is a really nice guy, but he has gotten so used to neckcranks from other MA he has trained, that he didn't realize neckcranks can **** up your back. I tried to make a frame with my hands, but I couldn't in this case because my arms was blocked(I can't exactly remember how), wich made me tap out a little to late (which is when it starts to hurt).

My advice. Know the different neckcranks, but don't apply them when training.
