Pro Deo 1.1 Betazoid T90h thinks Nd5 is the move to find here, after first
preferring Nd4 and Ne5, it puts its other Knight three times "en prise" and
stiil goes to plus 2 and a half! Maybe the Knight value has to go up a bit, if
somebody now proves that Nd5 is the "at all costs to avoid move"... Guess just
upgrading the Knights won't help then though :)

Proe Deo 1.1 default settings, after short period prefers Ne5, like Tony
Werten's Xinix does, and this move also gets a high score. Celeron 500 MHz, 28
