Tech

A tech, also called an ukemi or breakfall, is a special technique performed by pressing the shield button while tumbling when about to come into contact with the ground, a solid wall, or a ceiling. This allows the character to immediately recover from knockback and renders them invulnerable to attacks while doing so — potentially stopping a flurry of attacks or a combo. To tech the player needs to press the shield button 10 frames before hitting a surface and the player can tech immediately after being hit again.

Standard tech
A standing tech is a neutral, ground based tech that is performed by pressing the shield bottom right before hitting the ground. After the player techs, he/she will experience a period of invincibility, and will quicky bounce from the ground into a standing animation. This is the easiest tech to perform.

Rolling tech
A rolling tech ( also called a "techroll")  is a ground based tech that can be perform by pressing left or right while teching. The character will bounce from the ground into a rolling animation while moving either left or right with invincibility.

Wall tech
A wall tech is teching when you're about to hit a wall. In order to wall tech, you have to push the shield button right before hitting the wall and the character wall teching will experience a period of invincibility. It's most useful in a situation when a character is about to be stage spiked.

Wall tech jump/wall jump tech
If you jump when a wall tech is performed, then the teching character will wall jump. This is known as wall tech jump. Certain characters can wall jump normally, but everyone can wall tech jump. A skilled player can survive and recover from a stage spike by wall tech jumping.

Ceiling tech
A ceiling tech is a tech against a ceiling. To perform a ceiling tech, you have to press the shield button before hitting the ceiling. As with all the other techs the person will experience invincibility and the tech will absorb most of the momentum. Ceiling teching can even save a character who has 999% damage. However, it will be a lot harder to tech due to the speed of how far you going to be knocked back and few stages have ceilings for anyone to tech off from.

Ledge tech
If a character is recovering they can use a form of wall tech to survive an edge guarder. If the character is hit very near to the ledge, he or she can smash DI towards the ledge and wall tech to absorb all the knockback of the attack. This is performed by pressing the shield button to wall tech before inputting a direction. Another way to ledge tech is to simply wall tech when hitting the ledge and the character will automatically grab the ledge.

Tech chasing
Due to the static movement and invincibility of techs and get-up rolls, players can intentionally coax opponents into tech-rolling or get-up rolling in a direction and then chase them into a grab, smash attack, or another attack. This is especially useful for attacks that force an opponent into the tumble/crash-landing animation such as 's down smash.

Tech chasing is an integral part of high-level Super Smash Bros. play. A good example of a tech chasing setup in Super Smash Flash 2 is Fox's down throw, which forces opponents to lay down. Fox players can then anticipate what direction the player will choose to go in order to escape a follow-up attack, and then chase the opponent into another grab, then down throw, and repeat the process as many times as desired/possible.
