SDPC
Fig: SDPC bag structure. Includes DPC Recovery, which involves placing the extra piece in a specific spot compatible with a DPC setup.
SDPC is not 100% build cover on Bag 1. Use a fallback setup such as 8L PC Openers or 1st PC when SDPC isn't buildable.
From Bag 2 onwards SDPC 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 SDPC.

Second build shown is never necessary but may result in better KPP.

Some queues look like they might require a gravity wait, but that can actually be avoided using the following awkward L tuck:

Alternate input sequence exists:

⭐🩹 SDPC Default Complementary Recovery (2)
To be used in combination with Minimals. These recoveries cover all the fail queues.
You can often get a TSD with the save Z recovery.
⭐ SDPC Default Minimals (10)
SDPC Default Simple Extra (1)
Together with the two spin minimals this brings TSS rate to 53.89%.
SDPC Default Greedy Extra (2)
Two extra solves for full TSS rate.
However, as these both lead to J DPC, it might be advisable to forgo TSS and take a better save instead.
SDPC Default Useful (3)
First two solves are similar to some minimals. Use for better saves and/or easier solve.
Third solve has similar cover to second solve. Choose between the two for better KPP.
Last is to save I for VS.
If you can place ILO like this, the remaining field is 100% for any piece order:
The save O and save T solves often involve a 180 J-spin sequence:
Fig: SDPC J-spin 180 sequence.
After skimming before placing I, J can actually be kicked in without 180:
Fig: SDPC J kick finese without 180. However you since you're already here, you might as well just do washing machine instead :oyes:
If you can hold O after executing the TSD, you can still choose between SDPC Default and SDPC Alt:
Fig: SDPC hold O (99.68%). Choose between SDPC Default and SDPC Alt.

A full recovery route with 4 minimals exists.
While you never need most of these in practice, they're good to know if you make a mistake.
You can often get a TSD with the save O recovery.

If you can hold O after executing the TSD, you can still choose between SDPC Default and SDPC Alt:
Fig: SDPC hold O (99.68%). Choose between SDPC Default and SDPC Alt.
Since some SDPC Alt minimals are difficult to see, it might be advisable to not automatically build SDPC Alt whenever J<O, but instead build SDPC Default when O cannot be held.
When O can be held, look at the queue before placing O. Only build SDPC Alt when SDPC Default doesn't have a guaranteed good solve and SDPC Alt has a guaranteed simple solve for the queue.

Many solves are just congruents of SDPC Default solves:
If you can place ILO like this, the remaining field is 100% for any piece order:
Space divisions make finding solves simpler:
When T comes in the middle of the bag, it's sometimes possible to get the spin after skimming.
Skim in a way that creates a hole ready for the O piece to be placed last on top of the T slot.
Hold O until T has been placed:
When T comes too late, you'll often need to skim the top rows first.
Skim in a way that blocks off the T slot, ready for T to be placed last once the top rows have been resolved.
Here O cannot be used to resolve the space above the T slot because it would fall through.
Place O on the other side instead:
