Tsar Cannon/L<ZHCF

Fig: Tsar Cannon bag structure. Includes DPC Recovery, which involves placing the extra piece in a specific spot compatible with a DPC setup.
Tsar Cannon is not 100% build cover on Bag 1. Use a complementary setup when Tsar Cannon isn't buildable.
You can also use a fallback setup such as 8L PC Openers or 1st PC when Tsar Cannon isn't buildable.
Gamushiro & friends Bag 1 marked with 🇦️ and 🅱 have 100% combined build cover and 100% recovery rate into 100% DPC setups.
You must learn (build + recovery, not all solves) one of these combinations (🇦+🅱) in order to always be able to loop using Tsar Cannon.
From Bag 2 onwards Tsar Cannon setups marked with ⭐ have 100% combined build cover and 100% recovery rate into 100% DPC setups.
You must learn these setups in order to always be able to loop using Tsar Cannon.

This can be avoided if you forgo TST:

Space divisions make finding solves simpler:
Top portion of Tsar Cannon is partially symmetrical. However, solves aren't entirely symmetrical. Do pay attention to where the T-slot is.
Sometimes T can be spun in late using a spin sequence involving TST kick before performing the TSD:

You can build recovery instead of looking for a complicated solves.
Following useful L-spin is possible without 180:

This common solve usually starts by JLO skim and T-spin, but this exotic order requiring a spin sequence also exists for the same solve. Possible without 180:

There's this funny spin save L TSD utilising the TST kick:
