From Hard Drop - Tetris Wiki
Azyara Spin (Japanese: 戯（あじゃら）スピン) is an opener designed by player Claramay. It is a Triple Double Attack opener that has a chance to Perfect Clear (or PC) after 8 lines, which will lead into DPC. When a PC is not possible, you have the option to preemptively place the extra piece on top of the stack and complete the solve underneath it, which I will refer to as a compromise.
- Note: you may not always be able to do the "double" part of the "Triple Double." Because of the nature of the stack, it will be only a T-Spin Single. However, there is a possibility of a T-Spin Double when doing a particular skim during one of the solves, or when doing one of the compromises.
First Bag
This can always be built if you include the mirrored setup. With L before J, build it on the left side. With J before L, build it on the right side. For the purpose of this wiki page, only the left-sided version will the used.
Though not necessary, it is possible to spin the I piece in last as shown below.
- Disclaimer: because of the asymmetry of the I piece kicks in SRS, this does not work with the mirrored setup. However, this does not affect the build rate since you can hold, in the mirrored case, the Z piece and place the I piece before it.
Second Bag and PC
This can always be built with 180° rotations. If you lack 180° rotations, you may have to put the T in its spot prematurely.
From here, you have a 61.75% chance of a Perfect Clear with 3 minimals. The first and most common solve has a chance to get a Tetris PC, which will maintain Back-to-Back during DPC. If the Tetris PC cannot be taken, the J piece skims a line if the I and L pieces have been placed and leaves behind a space for a T-Spin Double, followed by the O piece.
If you are able to hold the S from the previous bag, the chances increase to 81.61%, and you gain access to five more minimals with the three most common being the same three above, so I will not list them again.
Compromises
Save O
The best compromise to go for is the Save O Compromise. The O piece can be placed on top of the build at any time, but it requires S before J for the solve to work.
Below are some examples of DPC setups that can be done with this O placement. These, along with their solves, can be found on the DPC Setups page. Additionally, because of the O placement, a two-line PC is also possible, which can make up for the previously missed PC. This will put you on TSZ 7th, which is also documented in the DPC page.
Save S/Z
If the Save O Compromise is not doable, you can do the Save S (or Z for the mirrored setup) Compromise. If you can see enough pieces in your queue to check for whether O is before S or vice versa, you can choose different placements.
Placement 1
Go for this placement if you can see O before S or an early Z piece in the next bag. It will also grant you a T-Spin Double.
Below are some examples of DPC setups that can be done with this S placement. The first one, along with its solves, can be found on the DPC Setups page. However, the second one is not on that page, so I will provide the solves for it.
Placement 2
You may not always be able to get a T-Spin with this placement, but it is safer than the other placement. The S piece can be placed on top of the build at any time, though you will preferably want to place the Z piece before doing so. Below is an example of how you could get a T-Spin Double, though you could also take a T-Spin Single followed by a Tetris. The same strategy of skimming with the J piece can be used in the other Save S/Z Compromise, or even in a regular solve.
Below is the DPC setup that can be done with this S placement. This, along with its solves, can be found on the DPC Setups page. You should always be able to build this if you are willing to take a regular double or singles instead of a T-Spin Double. The only time it would fail is if you had O and T as your active and held pieces at the very start of the build, which is very rare.
