There are some people who play Tetris who make the same mistake over and over again.
They are the ‘over-correctors’. Say you want to drop a piece one square away from the left-side-wall. A good player will move it all the way into place in one attempt.
A bad player will slam the piece all the way to the left-wall, then nudge it one space to the right.
On the face of it the bad player is doing the right thing; they’re always going to judge it correctly, and they are always going to avoid “miscounting” the correct landing column.
However the overcorrector will fail at speed – there just isn’t enough time to move the piece further than it needs to go, then move it back. It’s just not possible.
It’s a bit like life really.
Sometimes doing things the hard way is the best course of action.
Funny old world, eh?
(Ps. Anybody want to setup a Debian-tetrinet server somewhere public? I’ve got a lot of free time right now … :S)
