The key sentence is in the newspaper article is:
"The common basic wins that can be done in less than 50 moves must be memorized by anyone aspiring to mastery."
And you can rest ez'ly that the day you're playing for a Master's Title or Norm in a really big tournament ?....you will get this ending....it's Murphy's Law.
Also, knowing this gives you the confidence that you can reduce the game down to this and win w/ no worries & w/out embarrassing yourself. IOW's, maybe you don't deserve being a master if you don't know this one.

For those who are interested, here is Larry Evans' 1979 syndicated column on just this topic (below). It seems GM Walter Browne failed at corralling his silicon opponent's king and picking off the rook at first, but made it just under the wire in his second attempt.
For those interested in learning this ending and wanting more than a wordless database, I suggest John Nunn's Secrets of Pawnless Endings. Mr. Nunn does his usually thorough job analyzing and explaining it.
Yes, when my post at #11 got screwed up this was what I was coming in to mention (though I don't have the press cutting and couldn't have told you which GM it was). Belle was able in certain positions to defend by moving the Rook to a square from which "she" had calculated there was no forking continuation, and Browne wasted many moves trying to find one.
Notice that back in 1979 computers couldn't even beat Masters in whole games played under tournament rules (David Levy had a ten-year bet on that he won comfortably in 1978). But the difference in speed and power of modern computers compared to 37 years ago is almost unimaginable, especially from back then; let alone improvements in programming.
