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 is sends much 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 you start with SZ, you 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 you 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, you can build up further to unleash a large combo. Alternatively, you can do a STSD transfer.

Transfers

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