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.
Whichever way the overhang faces to, either J or L could be used.
It is good to keep in mind that the amount of the blocks 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, the shape above the overhang can vary. Below are some common situations, usually after a T-Spin Triple.
After the Tetris, players can basically do anything they want. But there are some suggestions that might increase efficiency.
Anchor Set could be used for things other than Tetris Stacking. There might be more usages than the ones shown below.
- Kaidan: 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.)
- Parapet: Anchor set could be used with Parapet for extra firepower. This one is especially used with the L Anchor.
- Forecasting: This technique may be used with forecasting. Below is an example of forecasting a T-Spin Double with this technique. Forecasting a T-Spin Triple or DT Cannon is also possible.
- 3-6 stacking: Anchor set could be used to convert an overhang into a 3-6 stacking. Either L or J could be used. The example below is adapted from a player's play.
- 2-7 stacking: This technique can also be used to convert such overhangs to 2-7 stacking.
