Illumination SD

Illumination SD is an opener similar to Sdpc conceived by Westl with help from the COpener server. Although the PC chance is slightly lower, it offers a wide variety of continuations that result in a clean field.

First Bag (TSS)

1st Bag

1st Bag

1st Bag Residue

The first bag is the same as SingleYou. Note that the L and J pieces are interchangeable.

Second Bag (100% TSD)

2nd Bag J -> L

2nd Bag L -> J

2nd Bag Residue

This is 100% buildable with 180 spins. Once again, L and J are interchangeable.

Continuations

The field left has a 90.99% chance of PC with 10 minimals. The most common solution may result in a TSD, and several others may result in a Tetris.

If one cannot PC or wishes to transition into midgame, there are 3 T-Spin paths that may be used:

Path 1

This path requires I before J.

3rd Bag (TSD, I -> J)

3rd Bag

3rd Bag Residue

4th Bag (100% TSD)

4th Bag

4th Bag Residue

5th Bag (TSD)

5th Bag (OSZ Ball)

5th Bag Residue

6th Bag (100% TSD + Tetris)

6th Bag L -> S

6th Bag S -> L

6th Bag Residue

6th Bag Residue

After the 6th bag, one can transition into 5-4 stacking. Note while all the other bags are 100% stackable, the 5th bag may fail on specific orders of OSZLT.

Path 2

This path requires J before I.

3rd Bag (TSD, J -> I)

3rd Bag

3rd Bag Residue

4th Bag

10-Height Perfect Clear

You have a small chance to do a 10-height perfect clear if L and S (or J and Z if mirrored) come early in the 4th bag.

TI

JI

JO

ZJ

STSD (Z -> S)

An STSD can almost always be stacked if Z comes before S.

4th Bag L -> O

4th bag O -> L

Do note that this is not stackable if J and T come before both Z and I.

TD Attack (Z -> JS)

One can also stack a Triple Double Attack if Z comes before both J and S.
