I thought of that, but I thought the difference of 77861 - 77796 = 65 was too
small to account for it. I figured one of them was counting a position like 1.e4
d6 2.Bb5+ Nf6, which is an illegal position. I thought the difference of 65 was
about right for this, but I was only guessing, so probably I'm wrong.
