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

The advantage to 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.

L

It is good to keep in mind that the amount of the pieces placed directly over the overhang can't 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.

Followups

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

Useful Usages

Anchor Set could be used for more things else than efficiency Tetris Stack. There might be more usage than the ones shown below.

Anchor Set could be used in tandem 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 in tandem 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.)
