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.

Advanced techniques must be learnt through experience, and cannot be feasibly taught.

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.

Much must be learnt from experience, and you will quickly see what pieces when placed in certain positions compromise your future stacking. When this happens, stop and examine the playfield, and determine the best position. Analyze your playing to better yourself.
