I think crafty was a bit unlucky to get this kind of opening. If crafty was
playing black im sure it would have won also. The Bishops were just too strong,
from the opening all the way to checkmate. If you want an example of the power
of the two bishops this is a good game to look at. All in all it was a very
interesting first game.
