Polymer T-Spins

General Setup
Empty Field Opening, created by player larrytetris:

Trehalose
Discovered by TCM-β, this is a Fin TSD - Neo TSD polymer.

Kojibiose
Discovered by TCM-β, this is a Fin TSD - TST polymer.

Midgame Opportunities
The polymer (trehalose) shape. At frame 3 is a fin-TSD followed by a normal TSD (because the step is too far for kaidan to work). It is fin-TSD at frame 11, followed by a polymer (fin-TSD + neo-TSD combo, i.e. trehalose). Explanation thanks to RandomTetris Noob, and fumen thanks to Larrytetris; further pages will be created on neo TSDs and Fins to explain these elements.

The Godspin
This is a little too extravagant to be doing for any other purpose except to "look extravagant". However, it's a decent exercise in understanding tspin polymer mechanics.
