He is not a simple character for sure.
In the Cbyer SUb Zero section you can find a tutorial video made by Pig and it is very useful.
By zoner people mean that if the char stays out of the opponents range could be very effective, like Shang Tsung.
Csz is not this type truly but an anti zoner, he can punish many zoners with his divekicks and with a good read.
He can be used for zoning with the help of his bars (ex freeze is fast and good) or he can use bombs not for zoning in the
classical meaning, but for space controlling, making your opp go wherever you want him to go, or react as you would like to.
Mindgames.
By rushdown they mean being in the face and constantly attacking from up close is the best, well Csz is very good here mostly because
he is one of the fastest characters in the game and he have a few very high damaging combos, great mixups. Mixups are set of moves
that will not connect as a combo, but most likely will make your opponent fail to defend against or counter so you can get a hit. Best if it involves
low, mid, and overhead attacks and Csz can mix them up perfeclty, with the addon of unblockable bombs.
There is one very important thing about him, that you need to watch out for your energy bar, for him it is nearly as important as his lifebar.
If you have 3bars you are sleeping. Or being scared. But you need to have at bars at least around 2 for a breaker, because of that he is so
energy bar depending he can be very fragile if not managed correctly. Still an ex-freeze or an ex-divekick can do a lot for you in the right time,
an ex-parry as a wakeup is just great, if you are sure you won't waste it. Ex-divekick can simply get you out from a corner and get your opp into one giving him a hard time.
Use his x-ray only if you need unbreakable damage and you are on the brink of death at the last round, but he can do much more with 3 specials, or 1 special and a breaker in hand.
Learn his combos, juggles, bomb cancels, you can find them in Pig-s tutorial, or in the stickied combo and juggle thread. There are many videos about this too. Do his mixups, and what is important know all of his options by heart, and always have the answer for a situation, this way he will be a horror, fast and deadly.
Good luck with him, and hope you will learn a lot here. ^^
