Anchor Set (アンカーセット) is a mid-game upstacking technique that can be used to ignore an overhang by making a Tetris near it. Use L or J mino as an "anchor" right beside the overhang.

The advantage of this technique is that it requires no softdrop. While the disadvantage is that a single misdrop, especially around the overhang, might be fatal.

Generic Structure

Whichever the overhang faces to, both J or L could be used.

J

L

It is good to keep in mind that the amount of the pieces placed directly over the overhang cannot be more than 4 rows for Anchor Set to be used effectively. Anything more than 4 rows might be hard to clean up and could render a single row (the overhang row) useless for a few bags.

In case of the J piece anchor set, the shape above the overhang can vary. Below are some examples of using it after a T-Spin Triple.

Followups

After the Tetris, players can basically do anything they want. But there are some suggestions that might increase efficiency.

J

(Left: T-Spin Triple; Right: Polymer T-Spins)

L

(Left: T-Spin Double; Center: Imperial Cross; Right: STSD)

Useful Usages

Anchor Set could be used for things other than Tetris Stacking. There might be more usage than the ones shown below.

Anchor Set could be used with Kaidan for extra firepower. This one is especially used with the J anchor. (The one shown below is one of the continuations of DT Cannon.)

Anchor set could be used with Parapet for extra firepower. This one is especially used with the L Anchor.

Anchor set could be used to convert an overhang into a 3-6 stacking. Both L or J could be used. (Nosomi Cannon continuation of Mr. T-Spin's STD is used.)
