Cheese Mouse

Cheese Mouse is an STSD opener created by SpikyLlama. This opener is useful for its wide number of continuations. However, it suffers from potentially slow starting due to wasting the T-piece for one to two bags.

First Bag
Requirements for the first bag are early I and Z.

Possible first bags are as follows. The first is ideal because you get B2B from the T-Spin Mini Single.

Second Bag
The second bag is used to finish the overhang and fill in the right. If you have an *extremely* late T, you may get one T-Spin Double in.

One potential way to stack your second bag is like this:

There's many ways to stack your second bag. It'll probably require some freestyling.

Third/Fourth Bag
This is where it gets interesting.

If you have an early J piece in your second or third bag and you used an S overhang, you can build a Trinity (or STSD if you have finished your second T-Spin Double) like so:

If you have an early J/L in your third bag and you did not use S for an overhang, you can build a T-Spin Triple like so:

Or you can take a late T-Spin Double:
