Thats it. You basically nailed it. You can use b13 to stagger and prevent a flawless block attempt. B142 is used to condition people to block the b13. Sometimes if the opponent is really sleeping you can do b1 stagger or b13 stagger and walk up and throw.Can you go into more detail how b131 gives them the illusion of control?
I noticed it gives great range on block for a backdash b2 whiff punish, but that's it
