I'd wondered about this. Baseball pitchers don't throw the worst pitch every time; you'd be expecting it. There has to be game theory here, too. Thanks for articulating it.

Maybe, but its not giving you the piece that worst on average, just the piece that is worst for the given situation. Well, tries to anyway.

Often they end up being the same, but not always. Tile the S's in a row and it will give you a cube because the s would let you complete the line.
