Ajanba TSD

Ajanba TSD was popularized by the Tetris player ajanba. It resembles the TKI 3 openers but the I piece is moved 1 column to the right. The first O piece needs to come early and the first bag is placed like this:

Second Bag and Later

6-line Perfect Clear (standard)

Eventually, the technique results in 2 T-Spin Doubles within the first 2 bags followed by a Perfect Clear opportunity after 6 cleared lines.

If the I piece shows up late in the second bag, then there is a chance to delay the first T-Spin and build a second T-Slot above. In this case the 2 T-Spin Doubles can be executed in quick succession and there is a Perfect Clear opportunity on top of it.

Agent 1568AH's continuations

These continuations chiefly involve placing the S, Z and I pieces on the left and the O piece and either J or L on the right. There is also a case if the O and L or J and O are placed before the T-Spin Double, then placing the I piece afterwards. In either case, you can make a Perfect Clear after either 6 or 8 total lines.

Perfect Clear after 6 lines

There are four ways to get a Perfect Clear after 6 lines. The first and third ways are the most ideal as you only need the I piece within the first 2 pieces of the third bag.

• S → I or Z → I and O → T → JL

• S → I or Z → I and J → T → O (L on hold)

• O → L and T → IJ (33.33% PC rate, 2 minimal solutions)

• J → O and T → IL (38.10% PC rate, 3 minimal solutions)

Perfect Clear after 8 lines

The best situation is that if you can make a T-Spin Double before placing L if the O piece is used or O if the J piece is used and also hold the remaining piece, you will get an extremely high Perfect Clear chance for both cases. As mentioned earlier, a similar situation is that the I piece is placed after the T-Spin Double.

• O → T → L or O → L and T → I (J on hold, 99.90% PC rate, 45 minimal solutions)

• J → T → O or J → O and T → I (L on hold, 99.84% PC rate, 49 minimal solutions)

If you must place the J piece and/or L piece, these are two of the good ways to stack for a Perfect Clear opportunity.

• Z → L + S → I or Z → I → L and O → J (100% PC rate, 65 minimal solutions): Even though one can always make a Perfect Clear in this situation, the first two setups above are more ideal because of the number of solutions.

• Z → L → O (96.79% PC rate, 30 minimal solutions)

Mofumofu Cannon

In the second bag, the O piece comes before J and the I piece comes before L. Afterwards, there are a lot of ways you can continue in the third bag.

8-line Perfect Clear

There is a 95.48% chance to get a Perfect Clear.

14-line Perfect Clear

For this continuation, in the third bag, you need an S piece before L and a Z piece before J then I. The fourth bag is always stacked the same way, leading to a 58.97% Perfect Clear chance in the fifth bag.
