Didn't analyze with diep of course. Might get subjective and quote diep. To prove Rac8 is equal to Rd3 you must prove that after Rc8 you manage to advance with black. And i just don't see it happen that you can prove that. After Rac8 black can only shuffle and hope his extra pawn wins the game (which it undoubtfully will manage in a computerish way after 90 moves). After Rd3 you are home with a full point before first time control. Vincent (and i'm really FM, in contradiction to what chessbase site nowadays says)
