In my computer playing with Deep Junior 8 from the following position
DJ8 made the same moves like in the game with Gandalf and draw. After playing
again from the following position, it didn't played so stupidly and won.
I'm confused. Perhaps it's position learning that made this, but anyway
there is a bug in DJ8 regarding this position.
My opinion is that in such games the final result must be set by the operator.
And in this case you have to set the result as a White WIN(1-0).
If Gandalf 5.0 had the resign option enabled then the score would be 1-0.
It's a pity that DJ8 outplayed Gandalf 5.0 and due to a bug he had only a draw.
