From Hard Drop Tetris Wiki
Acidic MT is a TSM > 100% TST opener created by 10Penta that has a high chance for an 8Line Perfect Clear, as well as other continuations.



First Bag
The first bag has a 56.7% build chance including mirrors, and requires early I and J (early I and L for mirror).



Second Bag
4Line Perfect Clear

If you keep the T on hold, you have a 23.0% chance for a 4L PC with 7 minimals.
100% TST
This can always be built.



3rd Bag 8Line Perfect Clear

If you keep the T on hold, you have a 94.4% chance for an 8L PC with 17 minimals. Note that most of the solutions are quite hard to spot.
3rd Bag Main Continuation
If you do not have a PC, cannot find a PC, have received garbage or do not want to do a PC, then you can follow this 100% TSS/TSD continuation:


The following 4th bag routes cover all bags:
Route 1 TSS S<T/Z or J<TS/TZ/SZ DTD
The 5th bags can easily be freestyled.





Route 2 TSD T<J, Z<S<O Quad – 14L PC / TSD



Note that there is another way to build the 4th bag:

After the 4th bag, you have a 51.3% chance for a 14L PC with the 2 minimals below, or you can continue with a TSD as below or freestyle.


ILJO Square TSD – 16L PC / TSD 18L PC
This can be built 84.4% of the time with ILJO interchangeable. If you keep T on hold, then you have a 41.9% chance for a 16L PC with 4 minimals.



For the 18L PC below, LJO is interchangeable.

You now have a 23.2% chance for an 18L PC with T on hold with 4 minimals.
100% TSD – 16L PC / TSD
This can always be built with LJO interchangeable. After the 5th bag, you have a 9.5% chance for a 16L PC with the 1 minimal below.



The four continuations below cover all bags with LJ interchangeable for the 2nd and 3rd images:
J<O 
S<O 
O<I 
I<J, O<S 
After the S<O case, you have a 28.1% chance for a 18L PC with T on hold with 6 minimals.
Route 3 TSD Z<J, O<S TSD



Here, you have 2 choices for 5th bag continuations:
Continuation 1 Quad / TripleTSS


LJO rectangle is interchangeable. Ideally, you do a quad, but if TI<S then you can do a triple followed by a TSS. This leaves a very good boardstate for downstacking or freestyling. Below are some examples of how to continue:
Fin TSD 
Neo TSD 
TST 
Iso TST 
TSD 
TSD 
Continuation 2 TSD – Quad
This can always be built with LJ and OSZ interchangeable.
100% 
T<Z 
Z<T 
Other 3rd Bag Continuations
Below are some other alternative 3rd bag continuations.
3rd Bag Skim Continuations
If you want to avoid all the complications of the main continuation and simply get a good boardstate to downstack or freestyle with, then you can follow these skim continuations.
J<O 

O<J 

Examples of continuations:
J<O
TSD 
TST 
Imperial Cross 
Fin TSD 
Neo TSD 
Tetrio 180 TSS 
O<J
TST 
STSD 
Vertical MT Cannon 
Fin TSD 
Neo TSD 
3rd bag STSD Continuation
Credits to winterfrost for discovering this. This STSD cont requires O<Z or Z<SO with OSZ interchangeable and has an 100% imperial cross followup. However, if you have L<O or L<T, then build it the second way to greatly increase the chance for a 14L PC.






If you built the imperial cross the first way, then you have an 8.9% chance for a 14L PC with T on hold with the 1 minimal below:

If you built the imperial cross the second way, then you have a 78.8% chance for a 14L PC with the 2 minimals below. Note that holding T from the previous bag does not increase the PC chance. If T comes first or second, then the chance increases to 100% and only the first solution below is required.


3rd Bag Mechanical TSD Continuation
Credits to ReallyNotSomeone for discovering this. This is an 100% skim TSD, and leads to a mechanical TSD. The 4th bag is also 100% with LJO interchangable.



If you hold T on the 4th bag, then you have a 60.0% chance for a 14L PC with 5 minimals. The most common solve, shown above, can be done 50.0% of the time. Otherwise, you can continue with mechanical TSD as below:
