The Basics

Winsor T-spin typically involves making a T-spin single, followed by a T-spin double.

To do the Winsor T-spin, do this:

Diagram Set 18-1
1	2

Starting mid-game opportunity.

One makes this shape with the L, I, S, and Z pieces.

The first T-spin is a single, with the T spun vertically like this.

This leaves this leftover shape that leads to a second T-spin.

Variants

Winsor T-spins have many variations beyond the most common one (variant 1) that most guides never cover:

1. Variant 1

This is the most common variation:

Diagram Set 18-3
1	2

For both sequences 18-2 and 18-3, you can let the base be made of an L or J piece instead of an I piece. Both transition to a T-spin double after the first T-spin single line clear.

2. Variant 2

In rare instances, the third T-spin can be a mini:

One makes A Winsor T-spin single.

The next T-spin is a single line clear.

The third one is a T-spin mini line clear.

Alt. A

This alternative pattern of a regular T-spin double follows from step 2 if the original sequence cannot be made.

3. Variant 3

Finally, you can use this variation to squeeze out an extra back-to-back T-spin mini:

This variant is mostly used during 6-3 stacking like this.

Make a T-spin mini. You will open up the next back-to-back T-spin double.

In a Nutshell

Winsor T-spins open up more mid-game T-spin opportunities. They are often used as a recovery method if other, more straightforward T-spins are unavailable.

Pros and Cons
Pros	It lets you make 2 quick T-spins. Provides extra T-spin chances when all others do not exist. Useful for using extra Ts for T-spinning rather than placing them in the stack.
Cons	Winsor’s initial T-spin single is weak, disrupts parity, requires a T to rebalance for continuations, and blocks the Tetris hole, adding risk.
