classic endgame puzzle


Haven't seen it before, and probably never will, as it seems highly unlikely (if not impossible) that such a position would ever occur in practical play. However, White seems to win easily enough:

BENCHMARK NOTICE: The above position has now officially appeared for the 10000000000000000000000000000000000000000000000000000000000000000000000000000th time on the forums of Chess.com. Not only is this a site record for appearances of any single position, but it is also the second-highest number of appearances for a chess position on any site!
