Stacking for Tetrises

Premise

This article will deal with the the skill of stacking for many consecutive tetrises. It will be biased towards SRS and guideline games. It is a work in progress. Stacking for tetris is a useful skill in games that reward B2B tetrises, or do not reward t-spins. There is an argument to be made that pure tetrising is more elegant than other methods that involves lesser clears or t-spins. see [1] for in-depth discussion.

Basics

Stack flat, but not too flat, to allow for s and z. in SRS, leave the column on the far right open for the I block to tetris in, as pieces are biased towards the left and you will save a few translations as they will move a smaller distance. Try not to create holes greater than 2 blocks deep, as this will require an I block that can be used for tetrising. However, a Tetris requires 10 pieces, so for roughly every 2nd tetris you have an I block to spare, if an I piece occurs roughly every 7 pieces, as is the case in 7-bag randomizer and such.
