When your sparring with smaller people is it fair to ask them not to use their flexibility and speed?
Personally I cannot stand it when I am sparring and some smaller dude pulls some funky hip / leverage movement that I could never do.
Of course the only solution is to simply throw them to the side/ stack them up and get into side mount and smother them with your chest hair. Although this is the moral victory, I cannot help feel that the other guy is missing the point.
However, if they simply slowed down and didn't move quite so much (and possibly eat more pies) it would be more fair.
