I have been working on the annoying butterfly guard to harass opponents, the rubber guard (since I am very flexible, I can skip some steps), leg locks, leg triangles, guillotines, omaplatas, gogoplatas, sorcerers, kimoras, wrist locks, armbars, the crucifix, and the asylum. My tactic is just to pull my opponent into my guard and from there decide what I should attack. If the attack fails, I quickly switch to the closest submission to the attack, only retreating when necessary. So, what are techniques that I need to know for a good closed and open guard game?
