The both programmes had to play on a blank sheet w/o any opening >libraries and using only the positional knowledge they really had. It is wrong to test a single position. If fruit does not understand some position that it get in the game it may make the same type of mistake again and again only because it is unlucky to get position that it does not understand. It is possible that A will beat B 20-0 with 1.e4 e5 no opening book after it and B will beat A 16-4 with 1.e4 c5 and no opening book after it. The main problem with testing a single position is that the same game may happen again and again so program that is bad in some opening line may fail inspite of being strong in another line.
