BJJ Rules

There are many resources and blogs that talk about brazilian jiu jitsu on the internet. Thousands and thousands of articles have been well written on the subject. What surprises me however how little discussion there is about the BJJ Rules.

BJJ rules is an important subject for anyone looking to compete. In my school for example we focus a lot on leg locks which is not normally part of the ordinary syllabus for brazilian jiu jitsu white belts.

I think it would be excellent if there was someone that could run through the rules and especially I think the illegal moves for each belt category because sometimes it is not entirely clear.

There is a move that I am practicing right now which is sort of a triangle body lock from the back which allows me to get the submission by crushing the stomach of my opponent. I can't quite understand whether this is a legal or illegal move under BJJ rules.

I think in competition the rules are not explained all that well and we would all benefit from a good quality explanation of this on the internet by an authoratitive figure.
