Albatross (アルバトロスSP)
An Air-TSD → TST → TSD "bird" opener. Many other bird openers that start with a floating TSD exist, but Albatross is the most widely used. You'll need an early O.
Having to soft drop during the first bag in many cases is a significant weakness of this opener.
T-Spin Continuation
People usually follow up with this. The traditional T-Spin continuation involves doing a TST → TSD.
Bag 2
Unless you get an early I, you will be able to complete a TST, as shown above. The next TSD will work for every bag.
If you get an early I, you can try the 8-height PC pattern shown below.
Bag 3
Depends on whether you get O before L or not.
Bag 4+
Bag 4 and onwards are done free-style.
The third field is friendly towards 7-2 stacking.
The first two fields have a 26.67% PC chance.
PC Continuation
6-height PC

This shape has a 100% chance of achieving a perfect clear. You can use this pattern when you get an early LI on your second bag. Rarely used.
8-height PC
This shape has a 41.13% chance. You will always be able to stack your second bag this way, so it's useful when you get an early I.
