Shining Aquas

Hello, I'm completely new to Guilty Gear (Started with Accent Core on the PS2 like 3 months ago) and to this website, and needless to say I've decided to play Anji. I apologize if anyone has already asked this: What is the most effective way to initiate Autoguard hits? I've been trying 6K and 6S, and on RARE circumstances 6H has worked, but what is the best way to practice the AG? Also, more importantly, is going for AG's worth it, or are you better off trying to play a normal pressure game?
