Side Switch

A Side Switch is a technique in which a character changes the side they are facing (IE left to right) in mid battle.

Description
Most characters have at least one side switch option (usually their back throw). Not all side switch tactics can be safe, such as diagnal jumping forward in close proximity of the opponent, usually the most reliable way to side switch is in the middle of a Juggle where the player has already confirmed the sequence for characters that have such options such as Ibuki and shown in the example.

Tactics
As Street Fighter games have borders to the left and right of the stages positioning can be a vital part of winning. This can especially be true against zoning style of characters that prefer to stay away such as Guile and Dhalsim. Side Switching for example when a player has been forced against a corner literally changes the pressure against the player who put them there in the first place. Spacing isn't usually as much of a factor in a battle of two aggressive characters but when battling one or in a battle where two characters depend on spacing pushing your opponent into the corner by any means necesary can decide the outcome of the battle.
