Pivoting, or DA Dashing, is a technique in Super Smash Bros., Super Smash Bros. Melee, and Super Smash Bros. for Nintendo 3DS that lets a character use attacks out of a dash.
In Smash 64 and Melee
In Smash 64 and Melee, the technique is the use of the time frame at which a character turns during a dash; any normal ground options are available as if the character were standing still - smashes, grabs and tilts can occur here without the lag that usually comes from using these attacks after a dash. Normal pivoting is primarily used so that a character can quickly change the direction they are facing whilst not suffering the usual turn-around lag that would occur when doing so. This can allow characters to improve the utility of various moves in certain situations.
The tactic was discovered by Philly Billy.
In Super Smash Bros. 4
In Super Smash Bros. for Nintendo 3DS, dash pivots exist, so the technique cannot be done the same way. However, if the A button is pressed while circle pad is flicked in the opposite direction, forward tilts, forward smashes, and item throws can be activated while running.
