Named so as the pattern of ISZ resembles an unlit Beacon. The first opening template existed beforehand in the Japanese Community as スピアード積み(Speerde Stacking).
This opener aims for a Kaidan in the second bag.
General Shape
To rotate the I into position J, LO, or JOL tetrominos must be placed if not performing a wallkick. In games with symmetrical I rotations this cannot be done with J alone.
The First Bag has a 20.00% Perfect Clear chance, 3 solutions.

|
Main Stacking Method
This can be assembled 85.56% of all bags with one soft-drop, or 90.87% for two or more.
With mirror these values become 92.38% and 95.24% respectively.
|
Heart Variation
By alternating the heart shapes this covers 78.89% of all bags, resulting in favourable residue to freestyle 6-3.
|
Common ideas are to keep L or O in hold to fix height difference after a floating T-spin.
|
|
|
|
Other frequent stacks include the folllowing, the latter of which results in a 51.75% Perfect Clear chance with other Perfect Clear continuations that lead to a potential loop.
|

These Mechanical TSD setups are also possible (see link):

|
All Cover Variation
Covers 100% of bags, can be used independantly or when the Heart variation fails.
- L>O: Use continuations accordingly for L>S or S>L. If possible, for L>S, hold S/Z to fix height difference after taking a T-spin, otherwise place Z rightmost always.
|
|
|
|
- O>L: Use the last diagram for the sequence SJO, provided by metallicLurker. For games with 180 the first diagram willl suffice

Tetris Stacking: Filling the centre cavity is highly freestyle, but there are also two donations available to use.

Perfect Clear
Stacking for a Tetris works for both T placements. It also provides a Perfect Clear chance after 8 Lines meaning one can use DPC Setups afterwards to return to a fresh bag.
- T>S/Z: 100% Perfect Clear chance, 72 unique solutions.
|
|
- S>T: 96.87% Perfect Clear chance, 55 unique solutions.
|
|
- Z>T: 94.68% Perfect Clear chance, 38 unique solutions.
