When a player gets too agressive, they are focused on offense and don’t think to block. That is the prime time to risk the IAT or instant air teleport.
If they rush in and you teleport behind them you might tag them with a fierce punch, and if you are close you can finish with the b.mk xx lp.Yogaflame. Throw a fireball if you knock down and try to IAT again for the fireball trap. With the fireball coming at them they might block than try to knock you out the air.
Does not apply to Zangief.
Also on crossups and on wake up. Back dashing is important. If you are cornered it is worth it to get hit to get out of the corner.
