I am a beginner so the notes will be of poor quality probably, but I will constantly update it as I learn.
Why I started this?
Why I continue doing it?
They compare BJJ with Chess and I agree partially. It involves understanding of a system, timing, pressure, lot of strategies, setting/avoiding traps, but most impotant of all is problem solving (especially in crunch time, in physically exhausted state).
Some notes from my class, instructionals, training partners and friends:
Principles of Guard passing
Knee on Belly (KOB)
Principles of Guard retention
Pin & submission Escapes
Side control escape
Shoulder joint locks (Americana & Kimura)
Straight leg lock
Btw, I also do Muay Thai and free style wrestling. <Insert Links>
