I see no way to force an exchange so it's hard to force a draw. I'd likely lose White's side even if best moves draw. It isn't easy for a rusty older player like myself.
Nevermind! As we now all know, it isn't easy for a shining almost new engine like Rykba neither.

Looks sound to me.
And now the question of the year: do you really think 1.Rh8+ together with let's say at least 2.Rh3 is the only correct line of the first two moves for white?

If I knew, Topalov or Anand would be preparing a match against me. :D The original game I thought should have been a draw. Did not think a full Bishop ahead with both sides having a pair of Rooks could lead to a win given the position. It's really an exhibition on the power of a Bishop.
