Nice Delphil 2.6a finish against Amundsen 0.80

Post by Graham Banks »

Not too difficult for White to win from the diagram position, but I liked 17.Nxh7. :)

Nice move Graham! Rainbow Serpent plays it after 14 seconds but intially thinks it only is a draw, it takes a while to go to one pawn up in the evaluation. The expected answer is taking the Knight and exchange it on f6 but maybe that would change at longer timecontrol.

Debugging is twice as hard as writing the code in the first
place. Therefore, if you write the code as cleverly as possible, you
are, by definition, not smart enough to debug it.
