'''Bidou''' ({{ja|微動|Bidō}}, ''Fine movement'') refers to a control scheme used exclusively for {{forwiiu}}. By moving a controller's right [[control stick]] while holding down corresponding button inputs, it is possible to register a left control stick input for only one [[frame]]. This makes many [[advanced technique]]s that would otherwise require frame perfect or precise inputs to be performed easily.

==Methods==
There are three known right stick configurations that allow for Bidou, all of which require a button and the right stick to be set to the same input. 
*'''[[Special move|Special]] Bidou''', the original and most well-known variation, requires the right stick and a button to be set to Special Move, and Attack + Special Move for smash attack to be turned off. Special Bidou inputs are performed by holding down the Special Move button and moving the right stick. 
*'''[[Smash attack|Smash]] Bidou''' requires the right stick to be set to Smash Attack, two different buttons to be set to [[Attack]] and Special Move, and Attack + Special Move for smash attack to be turned on. Smash Bidou inputs are performed by holding down the Attack and Special Move buttons and moving the right stick. Though it is obviously less efficient than Special Bidou due to requiring two inputs to be held down, it is the only method of Bidou available to the Wii Remote + Nunchuk combo, as Shake Smash cannot be remapped to anything else.
*'''[[Tilt attack|Tilt]] Bidou''', commonly known as "Aidou" and occasionally "Ghetto Bidou" because of the popularity of controller configurations that set the right stick to Attack, requires the right stick and a button to be set to Attack. Tilt Bidou inputs are performed by holding down the Attack button and moving the right stick. Unlike the other two variations, Tilt Bidou only yields tilt inputs, making it less useful. 

===Compatibility===
Because Bidou involves the use of both control sticks at the same time, it is common to set the shoulder buttons to [[Shield]], Attack, and Special Move, and either turn on Tap [[Jump]], or assign Jump to a fourth shoulder button if it is available. Therefore, it has varying levels of compatibility with controllers: 

*The [[Wii U Pro Controller]], [[Wii U GamePad]], and [[Classic Controller]] each have four shoulder buttons and a fully configurable right stick, making them ideal for Bidou. 
*The [[GameCube controller]]'s [[C-Stick]] acts as a configurable right stick, but it only features three shoulder buttons, so workarounds are required. The most common solution is to set the three shoulder buttons to Special, Shield, and Attack, and turn on Tap Jump. Alternatively, one can grip the right side of the controller in a claw fashion such that the player uses both their index finger and thumb for all the face buttons instead of just the thumb, allowing easier access to [[X]] and [[Y]] for Jump. The middle finger and ring finger are then resting on [[Z]] and [[R]] respectively, and one should change either X or Y to [[Grab]] for a complete control scheme and to avoid redundancy.
*The [[Wii Remote]] only has control stick functions on the [[directional pad]] and one shoulder button, making it impossible to perform Bidou with. Adding the [[Nunchuk]] supplies two more shoulder buttons, while opening up the directional pad for extra inputs; Shake Smash can act as the right stick, making it technically possible to perform Smash Bidou with the Wii Remote + Nunchuk combo, though Shake Smash is not as consistent as an actual right stick.
*The original [[3DS]] has only one control stick and two shoulder buttons, making it impossible to perform Bidou with. The New [[3DS]] features its own C-Stick and two additional shoulder buttons, but these cannot be configured using in-game tools; on top of this, {{for3ds}} only allows switching commands around and not assigning new commands. As the New 3DS console's C Stick can only perform Smash attacks by default, Smash Bidou is the only form of Bidou that can be naturally performed using in-game personalised controls. However, save data edits can set the C Stick to tilt or attack, making every form of Bidou available on New 3DS units. In {{forwiiu}} the additional mapping can hypothetically allow somewhat more comfortable control schemes; however, the limitations on the C-Stick and additional two triggers still apply.

==Applications==
With Bidou, the player essentially gets access to two smash directional inputs, which makes frame perfect inputs possible and makes full use of techniques such as perfect [[pivoting]], [[Dash-dance#Extended dash-dancing|extended dash-dancing]], and [[reverse aerial rush]]. With perfect pivoting, it becomes much easier to crouch during one with Bidou, due to the right stick supplying the pivot input, allowing the crouch to be done with a simple quarter-circle motion downwards with the left stick, rather than the precise inputs required by default. Perfect pivot crouches allow a character to [[space]] with more precision (similar to [[wavedash]]ing), [[sidestep]] during a perfect pivot (if Shield and then down are inputted after the perfect pivot), and safely approach at lower percents, since [[crouch cancel]]ling still exists to a lesser degree in ''Smash 4''. Extended-dash dancing and reverse aerial rushes can be pushed to the limit with Bidou, as alternating the sticks at the same time for extended-dash dancing tightens the character's oscillation (even for characters who would normally gain little benefit from extended-dash dancing with just the left stick over alternating [[Fox-trotting|fox-trot]]s, such as {{SSB4|Luigi}} or {{SSB4|Sheik}}), and reverse aerial rushes can be done simply by holding the left stick forwards, flicking the right stick in the opposite direction, and immediately jumping and attacking, leaving less room for lag in-between the inputs. Some character specific techniques are opened up with Bidou; instant ledge [[wall jump]]s allow for safer ledge trump edgeguards, as they do not use up the [[midair jump]], but can only be done on a few stages, particularly on stages with a wall under the ledge, such as [[Duck Hunt (stage)|Duck Hunt]]. [[Fast fall]] ledge trumps involving [[Item throw#Directions and strength|item drops]] are still complicated but are nevertheless easier to do with the right stick, as the right stick input down can be used as the fast fall input.

Other frame perfect techniques that are made easier include slow [[dash|runs]] (which would otherwise require precise control with the left stick), dashes out of [[walking]] animation (which would otherwise leave a few frames of lag, like reverse aerial rushes), pivot and attack out of [[interruptibility]] frames (which might otherwise cause the character to do a dash attack the other way instead of the attack desired, such as a down tilt), dash attack near the ledge (which might cause the character to careen off the ledge and aerial instead), and instant forward [[roll]] out of a character's running animation. The last technique in particular is only possible with Bidou, as unlike a forward roll after an initial dash, only one of two things can happen; either the shield will appear before the roll, or the character enters the skidding animation from stopping the run and can only jump out of the animation.

===Technical details===
Bidou takes advantage of the way inputs are handled in ''Smash 4''. Normally, a right stick input is treated as a 1-frame simultaneous input of a directional input of the appropriate strength and either Attack or Special Move, depending on what the right stick is set to. If the corresponding button input is held down, however, the additional Attack or Special Move right stick input is ignored, and only the 1-frame directional input is handled by the game. By holding down the buttons when they will not result in an action, the right stick can then be used as a special directional stick that registers 1-frame inputs only.

==History==
Bidou was brought into the spotlight by [[My Smash Corner]] from a [https://youtu.be/avr9CQlSqRI video] previously uploaded by a Japanese smasher. My Smash Corner claimed that Bidou had the potential to affect the [[metagame]], assuming players could master its capabilities. Bidou is a unique method of playing ''Smash'', since it requires a dedicated control scheme, and involves holding down buttons for extended periods of time, an input that is otherwise unheard of in ''Smash''. It is currently unpopular in terms of usage among most players attending tournaments, due to the difficulty and dedication in having to adapt to the unique control scheme, particularly for ''Smash'' veterans who have played with relatively unchanged controls for years. Nevertheless, it has gained some attention, due to hosting a variety of unique advantages compared to regular control schemes, and a number of players have been known to use Bidou in tournaments, such as {{Sm|ESAM}} when he plays {{SSB4|Pikachu}}.

Practically, the difficulty of consistently executing Bidou-specific techniques does not make up for its advantages, and no major tournament has ever been won by a player using Bidou.

==Tournament legality==
Officially, Bidou is not banned, and all tournaments allow players to customise their controls before a set starts. Bidou, however, derives most of its benefits from use of either the Wii U Pro Controller, the Wii U GamePad, or the Classic Controller, and all three controllers are generally banned in large tournaments for a number of reasons; the Wii U GamePad's inability to be transferred from console to console prevents two players who prefer the GamePad from playing, and both the Wii U Pro Controller and Classic Controller require syncing and unsyncing from the Wii U console, potentially leading to time constraints and other logistic issues at large tournaments.
