Byakko Soshoda

The Byakko Soshoda (White Tiger Twin Palm Strike) is one of Yang's special attacks, introduced in the Street Fighter III series.

Description
Executed by performing a quarter-circle backward motion and pressing punch, the attack is a simple two-handed pushing motion strike at around the level of Yang's abdomen. Similar to Yun's Kobokushi but with a longer range, the speed and damage are determined by the punch button used; light punch has the fastest execution and weakest damage, heavy punch has the slowest execution and the strongest damage, and medium punch is halfway between the two.

Street Fighter III series
Like Kobokushi, it has no EX version. Instead, using more than one punch button will perform a feint; Yun will draw back as if to perform the attack but does not. This is useful in baiting pre-emptive attacks or parries, as Yang can suddenly perform an unexpected attack.

Super Street Fighter IV: Arcade Edition
As with Kobokushi, the feint is now mapped to the light punch button, while the medium punch and heavy punch perform as usual, and are capable of stopping fireballs. Arcade Edition also adds an EX Special version.

Tactics
There is a significant amount of time taken to actually execute the attack; this means that it is often pre-empted by an opponent's attack. However, timed correctly, the attack is extremely powerful and its hitbox is such that it will hit an opponent who is performing a usually unassailable move. This is useful in baiting pre-emptive attacks or parries, as Yang will suddenly perform an unexpected attack instead.
