By the 'Beal effect' are you referring to "Random Evaluations in Chess", Don F. Beal and Michael C. Smith, ICCA Journal [17(1):3-9], March 1994? Is a text available for that publication? The article is also published in "Advances in Computer Chess 7", H.J. van den Herik, I.S. Herschberg and J.W.H.M...

I had not "background observe" switched on. That's why the first game was ruined!
