A forward smash, abbreviated f-smash and officially known as a side smash attack (横スマッシュ攻撃), is a smash attack that any character can perform by tapping the control stick (or d-pad in Super Smash Bros. 64) in a horizontal direction and pressing the attack button immediately afterward or simultaneously, or by tilting the C-Stick in a horizontal direction. Starting in Melee, forward smashes can be charged for a maximum of one second (or 60 frames), resulting in up to 40% higher damage and knockback.
After tapping the control stick forwards, there is a 3-frame window wherein a forward smash can be performed. If the attack button is pressed too late, a dash attack will be performed instead. Pressing the attack button on the last possible frame results in a small step forward smash. In all games except Super Smash Bros. Brawl, forward smashes can be pivoted.
Like forward tilts, certain forward smashes can be angled in up to 3 directions; a select few forward smashes in Smash 64, however, can be angled in up to 5 directions. In Smash 64 and Melee, the control stick or c-stick must be tapped in the desired angle at the start of the move to angle it. In Brawl and Super Smash Bros. 4, however, the attack can be angled by holding the control stick or c-stick in the desired angle as the move's charging period ends.
