Mr. T-Spin's STD

This is an opening created by player Mr. T-Spin. It is efficient in the sense that it doesn't waste any T's, the rate of success is extremely high, and that it starts the B2B early. It's also a good way to counter Center 4-Wide openings.

Mirrored Alternative to Mr Tspin
In the event that you get a late J, consider this:

OSZ in Second Bag
The O,S and Z pieces in the second bag can always be stacked in a way that a T-Spin Triple is prepared at the end of the bag. The order of the pieces in the second bag doesn't matter at all - the stack will always look the same at the beginning of the third bag.

Mr T-Spin Analogon
Left and right part swapped, so the T-Spin Triple overhang points towards the wall. This opening has the same dependencies as Mr. T-Spin's STD in the first bag (must place O before I and Z before L), and in the second bag O,S,Z must be stacked in the same way. After the execution, the only real difference is that the T-Spin Triple overhang points towards the closer wall which will result in different leftovers.

If I piece comes last in first bag, one can also drop it on the wall which allows to stack the T-Spin Triple overhang differently.

Pokemino's STD
Almost every game can be started with this opening. The only dependency in the first bag is that J must be placed before Z (respectively L before S in the mirrored setup). In contrast to Mr. T-Spin's STD it is not possible to entirely prepare a T-Spin Triple at the end of the second bag. That means if T comes first in third bag, then one T piece must be wasted.

Early I Piece
This setup has so many dependencies in the first bag that it is not really useful.

T-Spin Mini Zero 【JD砲】
This setup starts with a T-Spin Mini that clears no line. Afterwards it goes for a STD. Not really useful.
