SingleYou, or Single Double Perfect Clear (SDPC) (Japanese name SDパフェ), is an opener that starts with a T-Spin Single resulting in a 3-wide well. It is notable for having few dependencies (O before S, Z, and T) and many reliable continuations.

In all continuations, the first bag is stacked like so:

The routes differ from the second bag onward.

Perfect Clear

The original continuation, invented by Yuu. The term "SDPC" usually refers to this route.

By setting up a T-Spin Double as follows, one can achieve a high chance of an 8-line Perfect Clear.

The two main solutions are shown below. Together, these provide a 75% solve chance, with a 52% chance of a T-Spin Single or Double.

The remaining solutions are shown below. With these, the solve chance increases to 97%, with a 55% chance of a T-Spin Single or Double.

If a perfect clear is not possible or if the player has already been sent garbage, sometimes you can make a T-Spin Triple or an Imperial Cross.

Late J Tuck

If the J piece is late, but the Z isn't placed yet, you can avoid a mid-air tuck with a 180 rotation. This can be useful if you have fast soft drop.

Alternate O Placement

You can also place the O piece on the other side:

This allows for an increased Tetris chance, as well as an increased solve rate overall.

The solve chance for this setup is 98.5%, with 72% resulting in a T-Spin. There are 8 solutions where pieces are not split into 2 halves and they have the best chance of working: One of them will work for 88.5% of all third bags whereas 66% yield a T-Spin as well.

Motchi PC

Motchi PC (Japanese name もっちパフェ) is an additional set of three Perfect Clear setups that aim for almost 100% PC rate.

• LZ → I (100% PC rate, 14 minimal solutions): The best setup to go for if possible, with the first three solves covering almost 75% of all bags (and 86.6% for first five).

All solutions can be found here.

• All bags (99.96% PC rate, 15 minimal solutions): For cases where the above doesn't work out, you can always go for this. (First three cover 65.4% of bags, and first five cover 74.6% of bags)

All solutions can be found here.

• J → O (99.80% PC rate, 18 minimal solutions): This may be the lowest of the three, but it's still a very good extra setup to learn. (First three cover 69.3% of bags, and first five cover 78.4%)

Mechanical TSD v2

The second bag is stacked as in the #Perfect Clear.

From here, Mechanical TSD v2 can be stacked on top.
