Thanks. I suspected that this might be a known draw, so I looked for it in a
couple endgame books, but came up empty. I was surprised that other annotators
did not write about it. Actually, the commentators for the Braingames webcam did
mention it, but cast it aside as bad, because it "allows" Black to infiltrate
White's position via the White squares. Naturally, I could not convince myself
that their claim was accurate, hence my post.

I think after 46.f4, they could have agreed to a draw and shaken hands. I think
probably Kramnik rejected it for the same superficial reasons that the
Braingames commentators did. As you suggested, "he didn't know this book draw".

Note, the variations are significantly different with the King on f1 rather than
g1, so White should temporize with the rook rather than the King to keep things
simple.
