Hi,

Thank you very much for correcting me. This "bug" was very easy to correct :-)

Keep up the excellent work.

Thank you.

The last paragraph is not the same thing as what is quoted earlier:
"additional crossover compared to the opponent". This is very different
from 1 pip/checker.

See for instance fig.5, at page 31 from the article. Both players have 5
outfield checkers, totalling 6 crossovers for White and 5 for Red. Only
1, the difference in crossover counts, is added to White's Isight count.
