Fundamental moves and guards still are dominant and most important for growth.  However, it is fun to change it up and also a way to get a bump with some quick success...sometimes.  What is an unconventional submission/guard that you have success with?

The first one that pops in my head is the Tarikoplata or Octopus Guard.  Either one isn't something every person uses or has even heard about.  I have played around with both and still use both in my game today.
