Hey, thanks for the analysis!
Well, I often do 6H > Slidehead when I'm far to the opponent but not here because :
I didn't know it was a safe move (is it?), especially this close (pressing in the corner). I thought blocking or instant blocking the 6H could lead to IAD > combo over the Slidehead (I got punished a few times, maybe I was wrong). I won't do the OTG followup after the Slidehead, because we both agreed it was abused (and not very funny, I used once in the vid, maybe when we'll be better, I'll change my mind), so I think it's better to try varying my mixups. When I'm close to I-no, I tried many times to FRC the 6H into PB, but failed, haha. So it became 6H > nothing-wtf?!-just-throw-a-random-move without really thinking of what I could do after that.
Anyway, thanks for the answer, TheRealBobMan
