7. Sokolsky 1. b4 (-0.03)
   
8. Saragossa 1. c3 (-0.05)
9. Anderssen 1. a3 (-0.08)

There are some fluctuations of evaluation values but, basically, the situation is clear. Biggest surprises:

• The strong (2-4) place of van't Kruijs 1. e3.
• The weak place of English 1. c4.

I've calculated mean values and made the comparison table.

I love the Anderssen opening..
