Nice Delphil 2.6a finish against Amundsen 0.80

[Graham Banks]

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

[Eelco de Groot]

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.
