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 first diagram pattern 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 breaking the pattern.
|
|
Making a Super T-spin Double is only reliable when using the one or two extra layers of minos created by the Mechanical T-spin Double setup.
|
|
- T-spin Double → 5-4: For whatever reason one can always stack a T-Spin Double in some way.
|
|
|
- 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. See Interchangeable Shapes for all congruent JLO patterns.
|
|
|
- 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.
|
|
|
- 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.
