SZ Double Triple Setups

SZ Double Triple Attack, is a T-Spin combo designed by player XaeL. This setup is essentially a T-Spin Double followed by a T-Spin Triple. A player utilizes the SZ ST stacking setup followed by an extra piece to create a T-Spin Triple. This opening is an effective alternative to fiddlesworth in newer games which nerf T-Spin Singles to the point that the fiddlesworth opening sends a lot less garbage. This setup is especially useful when the beginning two pieces are S and Z.

This opening is effective for the following reasons:
 * Especially useful for SZ starts, where no I piece is present for the 3 T-Spin Double opening.
 * Most of the time, when one starts with SZ, they can do a Triple Double Attack. However, this requires foresight of pieces, to see whether a J or L comes first. The advantage of this setup is that as long as they have SZ at the start, it does not matter whether J or L come first. Hence it is beneficial when the player is slow at reading past the 3rd preview, or there are less than 4 previews available.
 * Fiddlesworth can require a significant amount of softdropping. This alleviates it, with only T-Spins using softdrops.
 * In games where T-Spin Singles and T-Spin Triples are negated or less potent, this is an effective replacement.

A negative of this opening is a piece is soft-dropped under the S. In situations where there is no soft-drop due to different piece order, chances are a Triple Double Attack opening, or a Three T-Spin Double opening can be used instead.

After the setup
After the T-Spin Triple, a T-Spin Single remains. If the stack is reasonably high, one can build up further to unleash a large combo. Alternatively, they can do an STSD transfer.

Infinite TST and C-Spin are also possible.

Transfers
STSD

This transfer can only be done if there are two blocks above the overhang.

T piece Overhang
Sometimes, if the T piece comes early in the second bag, one might have to waste the first T piece to be used as the overhang instead of the T-Spin Double. That means, the third T piece will be used for the T-Spin Triple. In the second bag, the L piece must be placed after the T-Spin Double.

Non Opening Examples
The following are examples for use when not at the beginning of the game:

Leaving a hole below S piece
In the following a cell is left empty in the bottom row and the T-Spin Triple becomes a T-Spin Double. The second bag's Z piece creates the overhang (instead of the first O or T piece) and the hole created in the first bag is uncovered after the second T-Spin.
