No, doesn’t need to be a CH. It’s just a very tight link - you have to FADC and dash out of the SA as early as possible and hit c.LP/LK immediately as the dash ends.
I usually plink c.LK~LP to combo after a SA FADC, since either crouching normal will do the trick.
If the opponent is close enough, just hk spiral arrow. If he is further away, you can try to hooligan him (work good at mp hooligan distance) - but don’t get predictable with it.
Low Forward XX Roundhouse Drill. Owns up Focus Attacks for free. Roundhouse Drill starts up fast enough so that if they absorb the Low Forward, they can’t get the Focus out in time before the Drill nails them.
Otherwise, just Focus yourself and Back Dash. That’s the standard way of escaping Focus Attacks. if they attack early, you absorb and run away. If they attack late, you just… run away.
Just don’t sit there, think for a second, and then try to jump backwards and get hit and die like I do all the time.
If you’re sure they will backdash then hooligan or spiral arrow are probably the best bets, you can probably option select one of them after a TK Strike.
The problem is that TKCS usually has enough of a delay that you can’t punish Back dashes with Options Selects quick enough, especially against the really fast Back Dashes like Rose and Chun. You can do it if you do a really early TKCS, but usually, you end up doing it later.
The best way to punish them, actually, is to, instead of TKCS, jump forward and do a regular Cannon Strike from the height of your Jump. Shorts work on most characters, but some might need Roundhouse Dive Kicks. If they don’t back dash, you’ll either hit them high up or land behind them, which puts you in a guessing game. But if they do Back Dash, you’ll hit them out of their Back Dash (usually which pops them up 'cause they are airborne) and then you can follow up from there.
i gotta respectfully disagree with you here, everytime i go for an option select arrow off tkcs, even against rose/chun i catch backdashes. it’s really easy to time it after a throw or after a initial strike to catch those 2 backdashes. i only bring this up because if you try to punish a backdash by jumping up and striking normally then you risk eating an AA, now against rose that’s not that large of a issue, but against chun her AA puts you back at full screen and forces you to get back in on her wall of pokes which is never fun. and yeah they can do that against the option select as well, but they have to do it on prediction, where as if you jump up they can do it on reaction
The Drill should work, but I’m often scared to use it because, a lot of the times, the backdash does complete fast enough that my Drill gets blocked and I die. But that’s because I tend to TKCS later than most people. I actually don’t do it perfectly Meaty, because, in a lot of cases, doing it perfectly Meaty means wake-ups catch you fully off the ground. EX Messiah Kicks, Chun Li EX SBKs, etc. When I do the TKCS a bit later, I get tagged out of the air most of the time. So yeah, for me, by the time they Back Dash, I’m still recovering so the Drill won’t work for me. But that’s just for me.
As for the Bird Kick hitting the high Dive Kick, that actually won’t work. That only works if you jump BEFORE they get up. I’ll just RIGHT when they get up, so if she does an EX Bird Kick, it usually MISSES me and I dive onto her. Don’t Jump high before they get up, jump from the same timing you would a TKCS and just do it higher up instead. That beats Back Dashes consistently. At that timing, they’d still have to guess whether to do an EX SBK and such and can’t rely on reaction.
That’s not entirely true. If you space it well you are +1 frames on block. You have to hit your opponent with the very last active frame and it’s safe. Go into training mode to find out what that distance is for lk, mk and HK. Try to hit people at max distance, but close enough to not miss them obviously. You can follow up with either block, CS or grab. I like to mix up these three to throw ppl off.
And like Seiku said. The first hit of the HKSA can be FADC’ed. If you FADC a blocked SA it’s usually best to go for the grab.
