Variants, Other Uses, and Comparisons

• One can build STMB Caves to extend above other T-Spin Doubles already on the field.

• One can also make an STMB Cave on top of another STMB Cave.

• Even without S/Z, an STMB Cave could still be made by using other pieces. Commonly L, J and I. Can also be done using T, but it is mostly ineffective since a single T is wasted in the process.

• Other than 3 columns wide holes, this technique could also be done on 5 and 7 columns wide holes. Only few people named it Yakine Variant after the player Yakine made the video about him making a 7-wide STMB Cave.

• A T-Spin Triple overhang could be used as an STMB Cave base. This is not recommended if the T-Spin Triple is done.

• An STMB Cave could be used along with Donation T-Spin Double for effective usage of pieces. As similarly seen in the Pelican Opener shown.

• It is moderately hard to spot the opportunity, but one could make a T-Spin Double cut T-Spin Double by using STMB Cave. One can also cut more than a one T-Spin Double. This technique is called Bennxt Prop, named after the player who introduced it.

Compare these variations of STMB Cave below with Cut copy. By definition, Cut copy is a technique where one invests a T shape underneath a T-Spin Double and the overhang for the second T-Spin could be placed beforehand for two consecutive T-Spin Doubles.

Comparison 2

Compare this variation of STMB Cave below with Shachiku Train. Although this variation uses a floating T-Spin Double over 3 columns wide hole, this still has the same shape and steps as Shachiku Train.

Compare these variations of STMB Cave below with Sky Prop. On some cases, STMB Cave is just Sky Prop but with 3 columns wide hole.

Comparison 2

Compare this variation of STMB Cave below with Kaidan. On these kinds of terrain, one could choose either one of these techniques depending on their NEXT queue after the T-Spin Double or the terrain left over after the T-Spin Double.
