Speaking of Caesar... if the AK you're fighting likes to j.C (at least I think it's C, it's the stupid jumping Caesar attack everyone spams to zone .), neutral/ back jump as he does from range and punish with j.D.
Also, I found out you can j.D his weaving movement.
I think the main goal of fighting this douche is to play keep away. If he weaves outside of 2A range... just chill out, j.D, or feint sweep. Feint sweep is to bait out a jump and maybe score a 2B. Sweep is a gamble, because it can be j.C on reaction from his weave. But because it can be punished so easily, play with their heads. Make them think they get a free punish, and 2B them to oblivion . Contrarily, with 50 meter for an OMC combo, sweep can have enough payout to make it worth the gamble.
