Some beautiful endgame studies

I'm tied up working today...doing tax returns (I'm a CPA) and also contributing to an exciting project for the Chicago Chess Center!  Will be getting back to pawn endings shortly, but in the meantime, here's a wonderful endgame lesson by WGM Jennifer Shahade, courtesy of our friends at the Chess Club and Scholastic Center of St. Louis:

The final study Jennifer looked at made me think of this famous position. 

  Schlage-Ahues, Berlin 1921: White to play and win


Schlage-Ahues, Berlin 1921: White to play and win

The geometry of the chessboard is peculiar.  By axiom, the shortest distance between two points is a straight line, but squares on a chessboard are not points in Euclidean space.  And for those of you who haven't had high school geometry yet, Kings always seem to move faster when they're moving diagonally. And if you get out a ruler, you'll fund that the diagonal-traveling kings are indeed logging more frequent flier miles per move on the chessboard.

You should be able to solve this position by trial and error: it's a lot easier than the ones demonstrated by Jennifer!
