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.
When referring to the term "TKI" or "TKI積み" (TKI setup), Japanese players always mean the TD attack setup, while western players mean the TKI 3 opening.

The C-Spin
Empty field Triple-Double setups are also known 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 cases have appropriate mirrors.
Other Cases:

Discovered by player Chopin. If you can manage to get a flat 6-high-mino stack, you might have a chance to trade the T-spin double for a Perfect Clear.
