Sailboat

Sailboat
Sailboat is a T-Spin Single into a T-Spin Single and then into a T-Spin Triple. This opener leaves you with several continuations aswell that you can use to your advantage. It is called Sailboat because of the shape you get when placing the first bag.

Basic setup
Beneath here you can see the basic setup for a Sailboat

Mirrored setup
As you can see, the S piece is on the wall this time rather than the Z piece, this way you can form the sailboat in a mirrored way.

Continuations
In the mirrored setup the stack has the following shape, if the only placed piece of the third bag was a T piece (used to make a T-Spin Triple).

Sailboat has many ways you can follow up with, as we will preview below.
