Curse

Under Construction Curse is an opener developed by Kerrmunism starting in January 2022, later being revisited on January 2023. The opener consists of a TSS -> TSD -> C-Spin in most cases (similar to Stickspin), though it can also go from the TSD into an STSD, or straight into a STSD without the TSD first. The opener is named due to it sounding like "Kerr's", as well as it allowing for Stickspin users to send similar amounts of garbage without having an early O.

First Bag
The first bag will always be stacked like this. The only dependencies are that you need L STSD instead.

Z<I
This is by far the most common build that you'll end up with, and perhaps the easiest to convert into a C-Spin. The build will be performed in one of the following ways, all of which are congruents of each other. Only the first 2 builds are needed to cover all bags, but the last 2 give better KPP (Keys per Piece)

You'll then end up with this board.

From here you have a number of ways to convert into a C-Spin.

As well as plenty of others that aren't shown. The main issue will be if you get Z or some combination of OSZ very early in this bag, in which case the C-Spin may not be possible to build.

Z<L and J<O / J<Z and O<L
This is the other major C-spin build for this opener. You're going to want to build it in one of the following two ways.

Both will result in the same board, shown below.

From here, you once again have a variety of ways to set up a C-spin.

S STSD
This is an alternate in the events that you get a late Z but also can't perform the second form of the second build shown, or if you simply want a mix-up.

It'll be built using the following form.

From here, you'll usually be able to fill it out in one of the following 2 ways.

Alternative Second Bags
These are second bags for if the others weren't possible to perform. They aren't as good and aren't recommended, but are available if you wish to use them.

STSD
This build simply requires O<S (O before S), and will be built this way.

From here, the rest would be freestyled.

This way of building an STSD in the second bag could also be used if you manage to keep your I piece in hold. It requires J<S (J before S).

Unlikely C-Spin
This is another C-Spin build, similar to the others shown in the main second bag section, however the dependencies for it to be pulled off make it extremely unlikely to come up. You need O<Z<J and L<S (O before Z, Z before J, L before S). It'll always be built like this.

If you do hit the miraculous odds to get this second bag, the third bag for it is extremely simplistic, with 2 builds covering every way to make a C-Spin.

100% 2nd Bag
This 2nd bag will be able to be built 100% of the time, simply producing a TSD, however it's not recommended to be used due to the holes it makes in your board.

Z<J C-Spin
This is an alternate C-spin build, however it only really can be followed up with a C-spin with good luck on the third bag.
