FD Spin

FD Spin is an opener with a series of Fin T-spin -> TSD setup by shenmirenwu3112. This opener requires I before L and J. One can 180 the L or J in.

The Fin T-spin can be done like this:

2nd Bag
The second bag can always be stacked like this: The S piece needs some spinning to fit in its place

3rd Bag
The 3rd bag can be stacked in different ways:

Variation 1
If I is earlier than L, one can consider this setup: After this one can also consider building this way. (100% setup chance) Or if O comes before L, one can consider this setup

One can also continue like this:

Variation 2
This variation requires L comes before J The I piece can be spun(requires 180 spin) into its place like this if it comes late: We can make a STMB cave here like this: We can continue it with LST stacking route or PC route.

PC route(84.76% PC chance): If L piece comes early, its 100% chance for PC. It has 12 minimals: Full PC solutions here.

If J comes early, we can also stack this way:

It will be easier to continue LST stacking with this and also with higher PC chance:

PC route (90.87% PC chance): It has only 2 minimals:

Variation 3
This setup is founded by Ivan28283. The setup chance is 100% with the L and O placements depending on which comes first.

L before O: O before L: One can do a J skim to make a T-spin shape out of the hole below: Then do some T-spin setups(The setups below are just some examples): Or a T-spin mini if one doesn't want to break the B2B chain:
