An advanced technique is an action or series of actions that are complex and/or technically demanding enough to require a considerable amount of skill, which results in a benefit to the metagame of a character.

Advanced techniques mainly differ from standard techniques in that their presence was not directly mentioned in any official capacity prior to release, usually due to not being discovered or expected to be a big deal by the game's designers. This often manifests itself in the form of advanced techniques being results of oversights or glitches, such as wavedashing and momentum cancelling. In the broader context of video games in general, their use is an example of what is known as emergent gameplay. A strong or properly-applied advanced technique can radically alter a character's metagame - for example, the short hop fast fall l-cancel provides a significant speed boost to a player's aerial assault and helps to patch up holes in slower characters' offenses. Certain characters rely heavily on their specific advanced techniques, such as the Ice Climbers' chain grabs and desynching techniques, and Fox's waveshine combos in Melee. Reliance of these techniques to shape top-level metagames and their often dubious origins is a common source of discontent among new and casual players.

In competitive playEdit

Advanced techniques are an integral aspect of high-level play and are sometimes essential for survival in a tournament. While the actual practicality and effectiveness of each technique vary wildly, knowing how to use them is still considered beneficial. As evidenced by older tier lists, some characters' standings in the metagame can rise significantly whenever a new piece of tech that revolutionizes how they play is discovered.

That being said, reliance on these techniques is a source of controversy, particularly with low-level competitors and casual players. Some raise concern that those without knowledge of these techniques are at an inherent disadvantage while playing. Depending on specific situations, some might be physically incapable of performing some popular techniques, which is not necessarily fair. Some also claim that using these techniques "breaks the rules" of the game by not typically being intended gameplay mechanics, and a banning of nearly every technique has been debated at some point for these reasons. While there have been some extreme examples like wobbling being banned due to being degeneratlely over-powered, most are not nearly at that level. Also, mastering these techniques are not required to be successful at a competitive level; they simply provide advantages and sometimes become core gameplay features of other games, which is why most are allowed to be used without restriction.
