50/50 : when you have a gap spacing after some combo string, and next, have an option to use either a overhead or a low attack, obligating your opponent to guess which one you gonna use
footsie : using movement, poking and bait , all the same time, to keep leading the pace of action .... more or less like having answer for almost everything your opponent gonna use against you, because you set up some spacing where you can predicate more or less what options your opponent is limited to use at that moment ..... and be at the good distance to punish, and at the same time, to evade from attacks.
zoning : to control space, limiting your opponent advancing ..... example : Noob Saibot using his shadow, following next with his shadow slide, this will keep pressure, and if at certain distance, your opponent try to jump forward to avoid, your try to use shadow knee to make him come back until the position is favorable for use to keep pressure again
