Crevasse Stacking is an opener inspired by HeboMAI Spin starting with a T-spin Mini Single. Afterwards the wide 'Crevasse' allows for various stacking methods.
First Bag
There are many sequences in which you can build this stack using a J-spin or S-spin. If T is in hold, considering the mirrored setup, a J is required before S or L before Z, if you cannot prop the S/Z on eachother.
|

|
General Stacking Methods
A T-spin Mini Single sends 0 lines on its own making long continuations risky in the context of versus multiplayer. It is possible to downstack while maintaining back-to-back but is situational.
- T-spin Double → 6-3: O is required before Z or can be soft-dropped in before the JS shape is made, 2nd diagram avoids potential S soft-drops.
|
|
- Imperial Cross: There are two ways of stacking an Imperial Cross depending whether O or L comes before S.
Afterwards one can choose to stack another Imperial Cross or continue ordinarily, in-depth continuations shown here.
|
|
|
|
An alternate setup with an added requirement of Z>O.
|
|
There are two ways to spin the J into place, if the I isn't placed soft-drop onto the S instead.
|
|
|
- T-spin Double → Shachiku Train: Completing the 2nd T-spin Double of Shachiku Train is often unfavourable, instead stack 5-4. The shachiku train is repeatable as shown here.
|
- T-spin Triple → Perfect Clear: 86.79% PC chance with 33 unique solutions here.
|
|
An alternate T-spin Triple setup.
|
Centre Well
A less commital stack which uses the second bag I to execute different techniques.
|
|
|
- STMB Cave → 5-4: Resolving the centre well dependency with an I and J is desirable but other options explored in Inferior Centre Well are also applicable here as the general stack is very similar.
|
|
|
|
|
|
- Mechanical TSD: A repeatable pattern that results in Floating T-spin Doubles. At any point one can donate the extra I, or break the pattern early on with an STSD.
|
|
- T-spin Double → 5-4: For whatever reason one can always stack a T-Spin Double like so.
|
|
|
- 8-Height Perfect Clear: This setup has a 99.25% PC chance with 124 unique solutions here. (URL too long- copy code starting v115 and load into another fumen)
|
|
Inferior Centre Well
An inferior centre well stack due to the uneven height difference on either side of the well, resulting in less stable and diverse stacking options.
|
|
|
- STMB Cave → 5-4: This can be difficult to convert to 5-4 without filling the centre dependency and wasting a T piece, unlike the original Centre Well. 2nd Diagram shows STSD opportunity.
|
|
|
|
The I L and J are all interchangeable, afterwards one can perform a count to 4.
|
|
|
Alternative STMB: Highly freestyle afterwards.
|
|
|
|
- 8-Height Perfect Clear: This setup has a 93.97% PC chance with I on hold. Without I on hold this becomes 90%, see the 48 unique solutions here.
