DAS Tapback

DAS Tapback can refer to an overall movement strategy, or simply a single type of move. It is often learned as a precursor to 2-step Finesse.

DAS Tapback movement
The key movement known as DAS Tapback is used for pieces placed exactly one spot away from the wall.
 * Charge DAS
 * While DAS is charging, rotate piece to desired orientation.
 * Wait for piece to hit wall
 * Press key in opposite direction
 * Press Hard drop

DAS Tapback movement technique
The DAS Tapback strategy involves three simple rules


 * Pieces against the wall should be DAS'ed then dropped
 * Pieces one away from the wall should be DAS'ed, tap-backed then dropped
 * Rotation always occurs before movement.

Using these three rules, it is very easy to learn DAS Tapback.

However, the more optimal form (2-step Finesse) requires unlearning a lot of the bad habits gained from learning this method. For example, may pieces one away from the wall in a non-neutral orientation, can instead be executed as:


 * Charge DAS
 * Wait for piece to hit wall
 * Neutral DAS
 * Rotate Piece
 * Drop

Which involves less keys since there is no tap-back.
