SDPC

SDPC is an 8l pc continuation of the singleyou opener,

which has the following first bag setup :

Default setup

T-spin requirements :

not [TZ]!O without mirror

not [TSZ]!O with mirror

Alternative placement

No build cover contribution

Slightly better finesse

For people with maximum urge to sdpc at all costs.

T-spin sequence

Sometimes need to softdrop J.

Advised to follow this sequence.

sd - das right - ccw

Hold on to softdrop.

No need to let go.

Different sequences of J may lead to fatal misdrops

sdpc motchi

100% pc

5040/5040 (0 fail)

Note that very few pieces are needed for a tsd.

TLZ pieces are always placed the same way.

It is possible to dump these pieces first and then choose which path to go for based on the queue.

You may want to learn the fail queues for each path if you want to make theoretically optimal choices.

78 fail queues

10 minimal solves

sdpc default solve :

this setup is always buildable with any bag, but also always avoidable with any bag.

can be categorized into 5 categories, with some additional solves you might like.

has the least pc chanc, but will serve as the foundation of other setups.

IOL base :

100% if IOL base can be placed immediately

IOJ base :

use different solve if this base has no solve

JSZ base :

may need funny spins, has save O/T solve

L skim :

easy to spot,

has save I solve

misc. :

not very intuitive but needs for full pc%

Extra solves :

below are just extra, not necessary for full pc% in sdpc default, but may be useful and may need in other setups

greedy tspins :

for full tspin chance, but saves into L/J

L skim extra :

one more solve for the L skim base

misc. extra :

sometimes useful

not hard to spot

Tips

Fail queues are the following :

xxxxTJL, xxxT[OJL]!

xxx ( xT / TJ / TI ) ZO

Categorizations are only for categorization and are arbitrary.

Solves may also be useful out of order.

In the 2nd bag, you may have to tuck in the L piece like in the first sequence in the right.

This sequence allows you to avoid gravity wait.

Other sequences exist but this is more advised to prevent misdrops.

Do not hold on to softdrop for too long and do hold on to left until the end of sequence.

Holding on to right will prevent any misdrops happening due to gravity.

Center of rotation colored purple for clarity.

sequence 1 : ccw - sd - 180 - right - cw - 180

If IOL base can be constructed immediately, remaining field is always solvable.
If T is accessible immediately, field is always solvable.

The first misc. solve and the three t-spin solves are the only ones needed in this case.

Do not construct IOJ base without thinking.

Although the solves are useful, you need to use a different solve for some queues.

Notice that the O piece is always in the same position, only except for one JSZ base solve.

In other words, O can always be placed the same way unless there is a need for JSZ base.

You may find the bottom two sequences on the right useful in JSZ base.

sequence 2 : Center of rotation colored purple for clarity.

cw - right - right - sd - 180 - ccw

sequence 3 : Center of rotation colored purple or yellow for clarity.

cw - sd - cw

Note that the last L skim solve and the last misc. solve are technically the same solve.

Still in a different category because it may be hard to imagine a T skim instead of a T-spin.

17 solves are listed here, but the actual minimal number of solves is 10.

More solves are intentionally included for consistency and intuitivity.

The extra solves are not necessary and does not contribute to pc chance.

However, they are still useful solves and are necessary for other 2nd bag setups below.

sdpc alt o

back to setups

SDPC

alt O

~ 99.13% pc

4996/5040

44 fail queues

20 minimal solves

sdpc alt o solve :

this part assumes familiarity with the sdpc default section above.

all sdpc default solves above (with one obvious exception) including the EXTRA solves are also needed for full pc chance.

only solves that are not in the above are listed.

alt IOL base :

identical to default

can use same solves

double <3 :

may include skims (total 12 solutions)

alt L skim :

one more L skim

also useful fallback

I-spin :

single heart + I-spin

T may be in heart

misc. :

single heart + I skim

beware the T

Tips :

Fail queues are the following (not practically memorizable though) :

xx ( xS / xI / IZ / IO ) TJL

xx ( S[ZT]! / Z[ST]! ) IO

xx (xZT / STZ ) OI

xxZ[TL]!OI, xxZ[IT]!OL

xxSTJOI, xxIOJTL

Categorizations are just for categorization. Solves may also be useful out of order.
Note that the leftmost O placement is congruent with sdpc default.
Note that alt IOL base is exactly congruent with default IOL base.

Everything that applies to default IOL base therefore also applies to alt IOL base.

Some solves are both an IOL base solve and a double heart solve. Shown in both categories.
Double heart solves also show some sdpc default solves just for consistency.
If T is accessible immediately, field is always solvable.

All T-spin solves can be used to always solve the field.

I-spin for the I-spin solutions is not one of those cursed I-spins.

It is done even without the use of any kicks. Sequence is shown in the right (cw - cw)

The last solve of the I-spin category may require a long S-spin sequence.

Sequence is shown in the right. Hold on to softdrop, no need to let go.

Center of rotation shown as red for clarity.

( right - sd - cw - cw - 180 - any 90 ) or ( das right - left - sd - ccw - ccw - 180 - any 90 )

Note that there is a "heart dependency" in the left side of the field.

It is always filled with the "heart" shape.

The misc. solves here might also resemble some of the misc. solves in sdpc default.
More solves than the minimal are intentionally included for consistency and intuitivity.

SDPC
hold O

~ 99.68% pc

5024/5040

16 fail queues

12 minimal solves

sdpc hold o

sdpc hold o solve :

this part assumes familiarity with the sdpc default and sdpc alt o section above.

no new solves other than sdpc default and sdpc alt o needed for full pc chance

hold o has only 12 minimals, even less than 20 for alt o. definitely worth giving extra attention to these solves.

also note that it is effectively see 8 even in a see 7 environment due to bag structure.

IOL base :

the identical base

can use same solves

double <3 :

may include skims (total 12 solutions)

JSZ base :

may need funny spins has save O/T

L skim :

all three L skims in one

helpful to know all

S-spin :

the funny solve from the I-spin category

misc. :

this one is from the misc. of sdpc default

Tips :

Fail queues are the following :

O - IxxSTJL

O - S ( Z / O ) xxTJL

O - Z ( IOS / Sxx / Oxx ) TJL

O - O ( IZS / Sxx / Zxx ) TJL

Note that all fail queues always end with TJL. The last L will not be visible before placing the O on hold.
Categorizations are just for categorization. Solves may also be useful out of order.
Note that IOL base and accessible T are both always solvable in both default and alt O.
No new solves other than sdpc default and alt O are introduced. Use the solves you already know and you are fine.
You may use the effective see 8 to your advantage if you wish to do so.
More solves than the minimal are intentionally included for consistency and intuitivity.

SDPC
alt J

~ 99.76% pc

5028/5040

12 fail queues

19 minimal solves

sdpc alt j

sdpc alt j solve :

this part assumes familiarity with the sdpc default section above.

only the L skim solve of sdpc default shown above is needed with the below solves are needed for full pc chance.

sdpc alt j is probably the most complicated and dynamic route of all.

it has 19 minimal solutions, technically one less than alt o, but solves vary a lot in shape which makes it harder to learn.

it is still good to know all other default solves.

only solves that are not in the above (with exceptions due to some falling into a category below) are listed.

JZI base :

probably the easiest set to remember

J base :

other solves with

the same J

<3 + T :

heart and I are

always on same side

antijeremy + T :

also has heart

but upside down

JS + Z base :

Z base instead of T

basically antipco

TS + Z base :

another Z base

basically hill

jaws :

awesome Z spins

often out of order

misc. :

useful fallbacks

needed for full pc%

Tips :

Fail queues are the following :

xxxJTIZ

xxSTZJI

xxTJ[SZ]!I

Categorizations are just for categorization. Solves may also be useful out of order.
Note that the rightmost J placement is congruent with sdpc default.
Note that there are two J bases, two T bases, and two Z bases.

The last two categories might be arguably called an S base, if it makes sense to readers.

The T base solves always have symmetry. Look closely to the field after placing the T.
Note that the heart part in heart+T solves are always in the same side with the I piece.
Heart+T also has one default solve, included for consistency.
JS+Z base may resemble antijeremy+T, but a Z piece instead of a T piece.
JS+Z base solves frequently have I- or Z-spin chances. Shown in the right.

sequence 1 : right - ccw - sd - cw

sequence 2 : hold on to softdrop, no need to let go (center of rotation colored purple)

( right - cw - sd - cw - 180 - any 90 ) or ( das right - left - sd - ccw - ccw - 180 - any 90 )

sequence 3 : hold on to softdrop, no need to let go (center of rotation colored yellow) :

sd - das right - ccw

jaws solve may need a Z-spin. Shown in the right.

sequence 4 : hold on to softdrop, no need to let go (center of rotation colored yellow) :

sd - das right - ccw

There are lots and lots of solves that are worth paying attention.

It is advised to take time to practice and explore the solves.

More solves than the minimal are intentionally included for consistency and intuitivity.

SDPC
hold J

100% pc

5040/5040

0 fail queues

7 minimal solves

sdpc hold j

sdpc hold j solve :

this part assumes familiarity with the sdpc default and sdpc alt j section above.

only one more solve other than sdpc default or sdpc alt j shown above is needed for full pc chance.

sdpc hold j is probably the best and easiest route of all.

it has only 7 minimal solutions, even less than 10 for default, so hold j is definitely worth learning.

also note that it is effectively see 8 even in a see 7 environment due to bag structure.

it is still good to know all other default and alt j solves. only the minimal solves are listed below.

default :

soles exclusively

from sdpc default

alt j :

solves exclusively

from sdpc alt j

both :

solves from both

default and alt j

neither :

one new solve

for 100% pc

Tips :

There are no fail queues. 100% pc chance. Do not ever fail to pc from here.
Categorizations are just for categorization. Solves may also be useful out of order.
Note that the rightmost J placement is congruent with sdpc default

and the leftmost J placement is congruent with sdpc alt J.

The 7 solves above are all you need to know for 100% pc chance. Very easy to solve.
The solve shown in the right may also be sometimes useful.
You may use the effective see 8 to your advantage if you wish to do so.
It may be possible to try optimizing solve chance even before placing several 2nd bag pieces.

Look at the queue for the first few pieces of bag 3 and try to see if there are one or more set of solves you can use for every possible sequence of the unknown pieces.

In other words, try to qb/oqb without commiting too many pieces if that sounds good to you.

Out of order solves may also be useful.

SDPC
motchi fallback

~99.96% pc

5038/5040

2 fail queues

15 minimal solves

motchi fallback

sdpc motchi fallback solve :

this part is an extra setup. this setup can always be built for any bag.

some solves may be in multiple categories at the same time in this section for consistency. do not be confused.

there are no tetris solves due to the I dependency in the left, but still has some T-spin chance.

T-mini base :

SO base possible

not hard as it looks

JT skim :

leaves o + heart

can be placed last

LJ base :

2 easy solves

useful to remember

L base :

alt J congruent

but instead uses L

SO base :

has overlap with

T-mini and ZO base

ZO base :

choose wisely of two

note the first solve

Tips :

Fail queues are the following :

[LS]!TJZOI

Categorizations are just for categorization. Solves may also be useful out of order.
Note the I dependency in the left. The I piece always goes there.

The T-mini and SO base are interesting enough to share many solves.

Arguably deserves its own category. Compound base shown in right.

Also note that the first solve of ZO base is congruent with the first solve of SO base.

OSZ ball part of the solve shown in right.

Note the Z placement in the last solve of SO base and the last solve of ZO base.

This placement is also interesting enough that it arguably deserves its own category.

One extra solve for this placement shown in right.

The L base is congruent to sdpc alt j with an I vertically placed in right.

Although the field is congruent, this time it used L instead of J, so beware the queue.

ZJ base might arguably also be a thing like shown in right. Useful solves to remember.

Despite of its high pc chance, extra setups may not have many T-spin solves.

If you are down for sacrificing pc chance for T-spins or tetrises,

it may be better to stick with the default set rather than the extra set.

During setup, S can still be placed after placing I if Z is not yet placed.

Center of rotation colored purple for clarity. Shown in right.

sdpc motchi

sdpc motchi solve :

no fail queues. do not ever fail to pc here.

this part assumes familiarity with the sdpc motchi fallback section above.

all motchi fallback solves can be reused out of order in many cases, but not as often as you might think.

below solves combined with all motchi fallback solves will let you always pc here.

only solves that are not in motchi fallback are listed below.

IL base :

may still resemble

some fallback solves

wrong default :

weird sdpc default

but not default solve

JS base :

potential tet solve

has grace solve

Tips :

There are no fail queues. Do not ever fail to pc here.

Categorizations are just for categorization. Solves may also be useful out of order.
All sdpc motchi fallback solves can be used, frequently out of order.

Solve in the right may also be useful. Also a potential tet solve.

Although not always, note that the I piece in IL base will probably be out of order in many cases.
Note that J is always vertical in IL base and always horizontal in the other two bases.
Note that I is horizontal only in IL base and the grace solve,

otherwise vertical in leftmost column.

Despite of its high pc chance, extra setups may not have many T-spin solves.

If you are down for sacrificing pc chance for T-spins or tetrises,

it may be better to stick with the default set rather than the extra set.

More solves than the minimal are intentionally included for consistency and intuitivity.
