The position is from a blitz game Zenker vs. WimpB (a computer program) on ICC July 2, 2007.

White finished the game with Re1-e8!

Not a difficult move to find, but esthetically pleasing, I think. The move also echoes some famous games where an unprotected piece can be captured in several different ways, to no avail. (See "Famous moves" on the previous page.)
