Triple Double Attack Setups

Triple Double Attack, sometimes referred to as Triple-Double, C-Spin, or just plainly TD, is a T-Spin combo that consists of a T-Spin Triple followed by a T-Spin Double. A player performs a T-Spin Triple that leads into a T-Spin Double.

The C-Spin
Empty field Triple-Double setups are also know as C-Spins. This name is given because of the "C" shape that is formed.

Notch
Notch is the most common Triple Double attack that is present in Multiplayer. Also, Triple Double is the best way to deal with a notch in garbage. The two basic cases are the following:

Case 1: J overhang + L triple to create  Triple Double

Case 2: Z/S overhang, L creates triple for Triple Double

Obviously both of these cases have appropriate mirrors
