Since Kg8 still draws and Ke8 is like mate in 31 or something like that it's not
hard to see that most programs would not be able to see that far ahead.  Chess
Tiger likes Kg8 with a score of -2.61 at 17 plies(White is winning).  But in the
earlier position if a person played Ra5 against me I would consider it an insult
since he is essentially saying I can't even draw with a pawn up in this ending.
If a GM played Ra5 and lost this game he got what he deserved.
