New Dubble is an opener which sends 1 line of garbage to block PC loops and PC spam.

First Bag

Setup rate is 100% if you switch around JLO box [1]

The second bag has 2 paths, one for PC chance, and one for more T Spin Doubles.

Second Bag PC Path

There are 2 routes from here:

L>S Leads to 100% 14 line PC (100% with 180, 99.96% without) [2]

S>L Leads to LST/6-3 stacking [2]

L>S

100% TSS [3]

Hold T (After TSS) is 100% 5L (14L total) PC with 180, 99.96% without, and also has a Quad chance [4]

4 minimals 100% with 180

7 minimals 99.96% without 180

100% Quad (After TSS) Use when you get sent garbage, freestyle from here (Note: O>T Still has PC chance, but requires learning more minimals) [4]

S>L

There are 2 routes after this, Z>O and O>Z

Z>O (S>L)

Z>O [3]

L/S>O (Z>O) Leads to 50% 14L PC [4]

4 minimals 50.83%

L/S>O 100% [5]

L/S>O 100% STSD Freestyle Left / Mech (Swap I and O every time) [6]

O>L (Z>O) [4]

O>L 100% Freestyle LST [5]

O>Z (S>L)

O>Z TSS [3]

(The continuation after this is extremely greedy, so if you can't greed, you can freestyle from here

100% Continuation Wastes 1 T but has high chance to lead to a spike focused board. [4]

Early S or S between JL Leads to good board state. [5]

If stacking like above is not possible, this is 100%, but you need good count to 4 vision. [5]

100% after early S or S between JL [6]

100% after the 100% after early S or S between JL (Freestyle From Here) [7]

Second Bag TSD Path

There are 3 routes from here:

L>O

Always possible to build with 180s

L>O 100% continuation

After this, you can freestyle another TSD

O>L, S>Z

After this, you can freestyle an LST stack

O>L, Z>S

O>L, Z>S Main Build

After this, you can freestyle a 6-3 stack

O>L, Z>S Compromise Build

This compromise build is only necessary if you get this queue: TZJLO (I and S doesn't matter)

After this, you can also freestyle a 6-3 stack.
