Suspension Bridge TSM

Suspension Bridge TSM (吊り橋TSM) is one of the openers that performs TSM on the first bag. It is possible to start from troublesome Z-pieces and S-pieces, and it is possible to derive LST Stacking with a high probability, so it is easy to generate firepower. This opener was invented by cerulean.

1st bag
TSM is performed; O-piece, J-piece, and L-piece are interchangeable for placement. The set-up rate is 83.33%, which is confirmed when the Z or S piece is stacked.

2nd bag
Perform TSD; there is an 88.10% probability that the left or ideal shape can be stacked. At this time, the O-piece, J-piece, L-piece, and I-piece are interchangeable in placement. When these cannot be stacked, they are stacked as shown on the right. The right or compromise shape can always be stacked. In this case, the O, J, and L pieces are interchangeable.

LST Stacking
From the ideal form, LST Stacking is possible. This is an example. O-piece, Z-piece, and S-piece are interchangeable in placement.

8-lines PC
From the ideal form, we have a 90.00% chance of performing a PC (9 filter solutions); the PC rate from TSM is 54.44% and from TSS is 6.67%.
