I hear you, Paladin, I learned mount escapes first class. I can get out from under mount consistantly, but I get pinned from side control.
And it's not just that opponent's are larger. They are much stronger. I'm about 175, 6'2''. but I have very little arm strength (TKD doesn't exactly foster upper-body muscles) so I have to rely on technique on the ground. All my opponents end up being huge guys that are about 20 or 30 years older than me and stronger and bigger, so I really can't muscle them off of me.
I'll ask my instructor about side escapes next chance I get. Good responses though, thanks everyone.
