Wongsz

Wongsz spin

Wong sz spin

2 bag SZ spin triple pattern into TSD.

First bag has a (theorised) 100% build rate mirrored, 180 spins are essential for piece order. Without mirrored some bags with an early combination of T, I, Z may not be possible.

Opener is best suited for all-spin. (I made this for fun and list continuations I think are interesting)

Main Variation

If T and I are placed, one can begin stacking imperial Cross early (S/O piece).

Left - O save | Right - S save

Imperial cross

Main continuation. From experience the imperial cross can always be stacked, shown are the most common and effective ways- most stacks shown are optimised to continue with freestyle trinity stacking.

The J piece can always 180 into place and one can begin stacking the cross with the saved S or O if the I/T are in place.

Third bag O is best placed on either side of the well to allow for s/z overhangs for trinity.

O save (O from 2nd bag placed early)

If I comes before the O L stack is made one can use this alternate stack, it it harder to stack cleanly afterwards but can almost always be made. Note the first bag I must be placed for the O to sit on instead of the T when stacking before initiating the Z spin triple.

S save (S from 2nd bag placed early on the left- allows for early I placement)

If O comes early 3rd bag and cannot be placed on either side of the well, one can place the saved O to the right side instead, this works for both variations.

Example of how Imperial cross can be made in many ways: (O save example, I've never tried but I assume you can TSS and I spin for all spin b2b)

An interesting trinity example after imperial cross (not necessarily recommended) one must 180 spin as shown to complete the TSD, this set of rotations also work with the L and Z piece. Use this to flex on your opponent.

Trinity

The Trinity/STSD shape can be useful for all spin.

Trinity stacking itself is not recommended as completing the first trinity without imperial cross has lower chances before the next T piece. Overhang depends on bag.

In all-spin using the T to make the overhang isn't fatal (see below). Building Trinity is freestyle but easier to stack from S save. Common stacks include:

The STSD shape is good for all spin as it allows a variety of different spins. This is why using a T to make the overhang is forgiving.

One can opt for a t-spin single in trinity to form either a t-spin or z-spin next. (See the Trinity hard drop page TSD Declined or Approved?)

Alternate Build

This variation offers stacks when the main variation does not work (most notably early S- diagram 3/4).

If possible it's generally better to use the T from the first bag to help stack the overhang first. It can be made in 4 ways:

Floating TSD/SSD

This continuation has a 100% build rate - the J O L stack can be vertically flipped depending on the bag, the floating TSD can be built before initiating the S/Z spin triple or substituted for an S spin double to avoid soft drop if the piece order allows for it.

One can make a TSD or produce an STSD after a TSS and skim (one can maintain b2b with an L spin if you can TSS early, even with S placed), the TSD is recommended:

The Z overhang can easily be made into a trinity (freestyle shown, not necessarily recommended)

All-spin fin

Best used in all-spin for b2b bonus. Can be made from either variations requiring an early I. See Polymer T-Spins to execute the tsd properly. Most fin setups can switch J and L, stack freestyle for a centre well. Z is required to fill the cavity.

A fractal can be made on all (except S overhang) stacks, this results in a high stack. The fractal can be amended with an L spin.

Alternate Build (wastes T not recommended- can easily be avoided by using one of the other four stacks)

Main Variation

SZ Loop

(Work in progress)

This pattern can be made when one encounters an early T and Z in their second bag, one can opt for an S spin double leading to a freestyle 5-4 stack. Usually the T overhang leads to cleaner residue. The left well can be freestyled but it's preferable to maintain a level centre for easier follow ups.

Using the T overhang one can usually convert this into a relatively freestyle Double Spin pattern. By holding the Z piece there are many ways to fill in the left well as the J/L or O piece can be placed rightmost.

When completing the Double Spin keep in mind the order, ideally you do two different spins but if you use one it's also possible to use the same piece twice.

After completing either spin it can be converted into triple double attack like the main variation, ideally in this case you S spin first as you will make a Z spin triple, however as mentioned before this is situational and either can be fine. One should aim to not waste their next Z but other overhangs are possible.

Alternatively you can create another Double Spin pattern if the J was placed rightmost, this is the basic setup but the rest is freestyle, example given.
