Hi Guy,

Close enough.  Crafty perfers:
1. a6 Bd4 2. Rg6+ Kf8 3. Bb7 Ke7 4. Rg5 h4 5. Rg4 Be3 6. Rxh4 Kf6 7. Rh8

The point of the position is that Black can't maintain his h-pawn, which then
opens up a second front for White ... essential for a win in this type of
ending.  If the h-pawns were not on the board Black could maintain a blockade
with this type of scheme: BR at a4, BB at e3 and White could not make progress.

Cheers,

Jim
