SZ Cross

The SZ Cross, is a T-Spin opening designed by player XaeL. This setup is essentially an unintuitive Imperial Cross. A player utilizes the SZ ST stacking setup opening followed by J and L to complete an Imperial Cross.

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.
 * 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 disadvantage of this opening is a Double which is used to create the Imperial Cross. This could be a problem where there is a very slow line-clear delay.
