What? No that makes no sense. Did Bastila's master know Battle Meditation? No, yet she could use it. Did Obi-Wan or Sidious teach Anakin Grip? No, yet he could use it. Yoda can't use it.
Sorry, I don't really know anything about Bastila. As for Anakin, of course, how else would he know it? Yoda can't use it? Surely if Luke can Yoda can. He's leagues above Luke.
The art is forbidden, but you are stuborn so okay they use choke. Kun defends the weak attacks and kills yoda. then he shows the jedi a real choke.
Forbidden, huh? Yeah, and so is killing an unarmed opponent, yes Mace was going to kill Sidious. Why? Because he's to dangerous to be left alive. Same with Kun. Defends the attacks? 11 Force Chokes coming from above avg. Masters, which include Mace, Obi-Wan and Anakin, while fending off Yoda. LOL.
