U4 set ups can lead to one of two things, U4 slide or U4 close bomb.
CSZ has a very powerful, no meter combo: If you divekick someone while they standing over a bomb, you can teleport, Njp them, U4 slide...this does 41 or 43%, I can't remember, but it's big damage for not much effort.
If you land his 2, 1, 1+2, a lot of players like to dash and hit U4 slide or U4 bomb.
J360 had a video where B1 is something like, +4 on block. It's slow, but you could always jail it off a blocked jip, plus, it also has quite good reach if you're mid screen. Lately i've been using this to hit B1, and go straight into 21 pressure.
I like to use B22 to get in or off a mid air punch, once in, I like to use 2, 21, 33, 34 for pressure. However he does have a very good d3 which you could use after a blocked b22. EDIT: forgot to add, if you land a 34, dash in with B22 into a bomb or slide. Others may have other things they like to do but I still think this is his best follow up from a 3,4 hit.
His fastest standing poke is standing 1 at 9 frames, you can full combo punish a blocked reptile dash, even online, with 11 ice ball.
Another thing, virtually all his standing attacks will hit a crouching opponent, even the ones with small hitbox like Mileena. Standing 11 can be ducked, but that's about it, but 111 can't be ducked (last 1 will hit crouching).
The others have a bit more experience and I would definitely hit up
J360 for CSZ advice.
He's a good pressure machine and even does well against other pressure monsters like Cage, KL, Kabal, etc.....but he struggles with zoners, especially those with air projectiles.
