Mr. T-Spin's STD
A TSS → TST → TSD opener that can be used when you have an early SZ start.
One of the advantages of this opener is that you will not need to soft drop your pieces when setting up your first two T-Spins.
Devised by Mr. T-Spin.
Going for an STSD could be a good way to continue from the TSD.
Same as above
Depending on your piece order, you may need to soft drop your O and spin in your T.
