>In Street Fighter 4, there is an undocumented technique termed the "delayed crouch reversal focus attack dash cancel" that was only recently discovered and kept hidden by professional Japanese players after the installation of Super Street Fighter 4: Arcade Edition 2012. It was primarily done defensively on wake-up. The technique can be performed by buffering this specific input sequence within 10 frames of the throw tech window:
>632 (just before wake-up) 1+HP (reversal input) ~ LP+LK (throw) xx [MP+MK (focus) xx 44/66 (back-dash/forward-dash)]
>where the symbols denotes as follows:
>6,3,2,1 = forward, down, down-forward, down-back respectively
>HP = Heavy punch
>LP, LK, MP, MK = light punch, light kick, medium punch, and medium kick respectively
>~ = 1 frame delay
>xx = special cancel
>Due to the input and buffering leniency in the SF4 engine, the exact outcome of this technique is determined completely by the opponent's pressure choice against the player's wake-up. But for all decisions, the outcome will always favor the player that's performing the technique:
>Opponent tries a meaty attack -> Player will block safely
>Opponent tries a throw -> Player will throw tech and revert back to neutral safely
>Opponent tries a delayed attack or frame trap combo -> Player will automatically reversal and cancel into a FADC (focus attack dash cancel) dash-forward combo
>The only way to counter the technique is actually counter-intuitive: give up your pressure opportunity. The player will still automatically reversal, but safely cancel into FADC back-dash and reset back to neutral.
>Most notable players that abuse this technique are Japan-trained Luffy (champion of EVO 2014), Momochi (champion of EVO 2015), and Daigo Umehara (grand finalist of CC 2015). The technique gave them all the illusion of seemly able to perform their "psychic" reversals without any fear, which would normally be risky and punished if not special canceled.
