T-Spin notes.

T kicks in SRS

Oshisaure had a table somewhere but I lost it, so here it is again. Note that CCW kicks are mirrored.

Rotation	Initial state	Kick 1	Kick 2	Kick 3	Kick 4	Kick 5
u, CW					impossible
r, CW
d, CW				impossible
l, CW

Kicks that can satisfy 3-corner

Rotation	Kick 1	Kick 2	Kick 3	Kick 4	Kick 5
u -> r/l	Yes (either)	Yes (mini)	Yes (mini)	n/a	Yes (either)
r/l -> d	Yes (either)	No	Yes (full)	Yes (either)	Yes (mini)
d -> l/r	Yes (either)	Yes (mini)	n/a	Yes (either)	Yes (mini)
l/r -> u	Yes (either)	No	Yes (mini)	Yes (either)	Yes (full)

Notes by kick:

• 1 is base rotation
• 2 only gives minis (sideways-pointing minis) that may or may not be immobile.
• 3 leads to the alternate way of the classic TSD kick (if going to d) and the only way to get upwards-pointing minis.
• 4 is the Neo MTSD kick. It's not clear if there's a legal setup for getting full 3-corner with the kick going to u (doesn't look like it).
• 5 is the TST kick, but only gives TSTs if starting from u. If l/r, it becomes a curious up-kick; it's not clear if one can legally reach a full 3-corner going to u using that kick though (doesn't look like it either)

Test cases

The minimum required to satisfy all rules is 3-corner with pointing side and the back of the T not facing a wall or floor.
