Hi, I need some general 'playing against Sheik' advice...
1. How should you DI the following moves? Right now I feel like a pincushion and it's definitely because of MU inexperience. Let me know if there is no correct DI (i.e. you should mix it up) instead.
-Fthrow (low%)
-Fthrow (kill%, i.e. Sheik is looking to follow up with uair/etc.)
-Dthrow
-Fairplane (repeated rising SHFF fairs)
-Uair (what is the best survival DI?)
-UpB (hate to get caught by this but if I do it always seems to send me at a weird angle)
-Nair (if I'm expecting BF after)
2. I have read conflicting advice on this subforum about the safeness of fair on shield. I know with air-to-ground things it can be finicky (powershield? + frames to land + autocancel windows), but in general if I'm close enough to get out a standard frame 6-7 grab OoS, can it be done or will I eat a jab/ftilt?
3. Very specific question, but what about Mario's Up B OoS? Could it beat Fair? Ftilt? By 'beat' I mean 'punish before Sheik could shield'. I would test this myself but I don't have someone else around to hit buttons.
4. When I'm at kill/50-50 percents, how should I play the anti-grab game? I usually try to stay airborne but then eat some needles because of it. Is there a better way to avoid the kill?
I was also going to ask about neutral but that gets pretty character-specific and there are MU threads for that.
How to DI stuff
1. Fthrow at low %
Up and towards to avoid BF, up and away/down and away to avoid upair/nair/fair. Mix up between those two.
2. Fthrow at Kill %
To avoid upair DI away/down and away. With this DI you'll be in a 50/50 with Bouncing Fish. You can break sheik's BF 50/50s by airdodging in reaction to the BF sound. Takes practice but you'll never get hit by a sheik BF 50/50 again :D Sheik can also do dthrow if they expect DI away and it's another nice BF 50/50 because fthrow DI away is still pretty hard to 50/50 with at high %s. So mostly di away but sometimes mix it up with DI in or something.
3. Fairplane
Depends on character. As a fast faller DI away and you'll eat 1 less fair than normal if it's off a low % throw. As a floaty di up and away. DI up can also be good at low/mid %s as sheik will eventually have to fullhop and that makes fair stuff less guaranteed. We'll normally try and falling fair, nair or upair after a fullhop fair so watch out for those.
4. Upair
Best survival DI is away (maybe away and slighty down, i'm not 100% sure) from the direction sheik is facing. Pretty easy to tell because her body is on an angle. / means facing right \ means facing left.
Now, that is the way you'll have to DI against MOST sheik players. Sheik can actually mix up your DI with upair, by hitting with the back hit and sending you the opposite way. Void does this a lot which is why you see top players somehow DIing it dreadfully wrong. I actually don't know how to tell what way to DI when on the receiving end of the DI mixup, all I know is how to execute it. You'll normally just need to DI away from the direction sheik is facing against most sheiks though. It's not too widely known.
If they do know how to do it, you'll be able to tell if you're DIing how I've said then go straight up. Most sheiks will only go for the DI mixup at kill %s. Then it becomes a reading-their-mixup game. If they get it once at high % they'll probably go for it again when you're at high % on your next stock, so DI the opposite way to normal. When they see you DIing right they'll start mixing up, so just hope you guess correctly if they'll do it or not.
I'm sorry I can't tell you how to just tell (there definitely is a way because some players consistently DI it right, I just don't know it).
5. UpB
Depends where you are on the stage. If you're near the sides then di in. If you're near the top then di out. Out/in depending on which side of sheik you were hit by. Hit by the front? Out from where they're facing. Hit by the back? other direction.
6. Nair
If you're not hit offstage DI down and tech. Can be risky sometimes because sheik nair is great for untechable setups with the spin. Otherwise mix up between away and up. Be careful with up though, as if you're still not offstage then it can true combo into tipper upsmash and you'll die early.
Sheik's fair on shield doesn't have frame advantage (or it might be +1 I actually don't know because it doesn't really matter). What matters is the sheiks spacing. If they hit with a close fair (which does 4% unstale) then a normal speed grab oos or footstool oos is good. If they space well and hit with the tip of fair (does 5% so more shield stun) then they'll be too far for you to do anything, so just jump or roll away.
If you expect fair > jab jab, it will trade or beat grab if you don't react fast enough, so you can play it safe and shield the jab 1-2. Sheik's jab 1 and 2 are far from safe on shield, so grab or roll or jump or something.
Mario upb oos
for ftilt you'd probably have to do an impact option select (go to onesmash.net they have great tech vids) or just shield grab. Only shield grab or upb if it's close ftilt though. Spaced ftilt will make you look silly. Same with fair. I'm not 100% sure about upb oos but I'd say only do it if they're close not spaced.
Sheik's grabs no longer setup into nice 50/50s, so just shield a lot. Of course always mix up, but shield most of the time because all sheik can do with a grab is put you in a bad position and try and punish landing or get you with a BF 50/50 if you don't know how to deal with them. Normally just jump out of sheik's grabs/ftilts at 50/50 %, unless you're on T&C, then airdodge should be used a little more than normal.
Hope this helps.
