Reliable TSD is a single bag T-Spin Double opener invented by Yuu. It was designed to guarantee three TSDs if you could build the first bag. It requires J before Z, and I or L before S.

Introduction

First Bag

The I and L pieces can be spun in:

Second Bag+

From here, there are two main routes.

• Traditional Route

This route can be used as a compromise setup for the two routes below.

• 3D Cannon Route

In the second bag, the ILSJ box can be changed. This route has a small chance of failing, for example in the bag LTJZISO.

• Slayer PC

There is a 3rd route created by Nightslayor that has a 93.57% (4716/5040) to PC and can be made 1/3 times.
