Reti Endgame Study

[jts]

Probably every person who is familiar with chess has seen this.

In chess, unlike in geometry, the shortest distance between 2 points is not necessarily a straight line. And in chess, unlike in geometry, it is possible to go 2 directions at the same time. This composition  is elegant in its simplicity (only 1 pawn each side, you can't get much simpler than that) and is almost magical in its defiance of geometry. Maybe some people will call it a paradox, like Aristotle's wheel paradox.
