Chocobar (V3) is a tsm opener created by bubbles (hypersonicstorm). It has a very high 96.90% chance (different 4th bag that sometimes needs gravity wait; one shown has about a 73% chance) of getting a Tetris PC.

Chocobar V1

pretty useless; might not add

Chocobar V2

will probably add sometime

First Bag

The first 3 builds are recommended. The 2nd last build is pretty rare, and the last build is only needed if you want to maximize setup chance and do not care about btb.

Tsm chance (with 180 spins) 68.39% without mirroring and 77.86% with mirroring. Tsm chance (without 180 spins) 68.29% without mirroring and 77.06% with mirroring.

If you do not care about tsm btb, learning the last build build (as well as skimming the other setups) brings the setup chance up to 95.83% with mirroring and 92.35% without mirroring.

Second Bag

T-Spin Double

This has a 100% build chance.

Third Bag

T-Spin Double

This has a 100% build chance.

Fourth Bag

T-Spin Double and hold Z

This has a 100% build chance.

Fifth Bag PC

100% chance of achieving a Perfect Clear with four minimal solutions (there are 4 congruent solves, which makes solving easier. ZLJ skim at the bottom, and use the congruent shape on the very top if S>Z, and the one below that if Z>S. The 4 congruent solves add up to 99.68% PC.)

Congruent shapes. Might be helpful for visualizing (the first 3) solves.

Fifth Bag TSD

One can also do a T-Spin Double that leads into a T-Spin Triple

First build should work most of the time with 180 spins.
