Double Triple Cannon 2 (DT2)

The Double Triple Cannon 2, also known as the DT Cannon 2, Double Triple 2 or DT2, is a variation on the Double Triple Cannon. Rather than having a "large notch" (as with the DT Cannon) that is cleared by a T-Spin Double followed by a T-Spin Triple, in the DT Cannon 2, the T-Spin Double and T-Spin Triple are cleared by separate notches. However, similarly to the DT Cannon, the DT Cannon 2 does have a notch for the T-Spin Double on the same side as its overhang.

Wall-Overhang Variation
This is the preferred way to set up the DT-Cannon 2.

Wall-Notches Variation
The wall-notches variation of the DT-Cannon 2 is actually one of the harder setups to master. It can only be made by transferring or trimming blocks, therefore it is only practical in mid-game.
