T-spin Triple →
A recognized T-spin clearing three rows. Its deep slot needs a suitable overhang and rotation entry; building a tall T-shaped hole alone does not ensure the T can get inside.

Planning a spin or placement for the board that will exist after an earlier clear. Mentally remove the clearing rows first; the setup's supports and overhang may move into place afterward.
