I think I can sort of answer that question. The 2A > Parry OS is pretty simple. After Liz does 5C, she will typically go into either 2C or 5D. When Aki responds with 2A > Parry after a 5C, if Liz does: 2C: Thanatos armors through the 2A, but your have enough time to input your parry and kill Thanatos with it. 5D: 2A kills Thanatos and parry will recover fast enough that Liz won't be able to do anything about it. This OS isn't infallible though. If the Liz catches on, she does have options to counter it. It loses to both A and SB Bufu, OMC > 5C, and, if you're using B Parry, an awakened D Agi. Honestly, if your connection is good enough, you should be able to react to whatever Liz is doing. Ideally, you should just block low unless you notice Liz doing her grab animation, then punish whatever it is she did assuming she doesn't try to OMC.

Are west coast participants allowed in this tournament? I'd love to give it a shot, but from the looks of it pretty much everyone there is east coast.
