I will append the game with the scores of Yace. I believe, a better knowledge
about 2 conntected passers on rank 6 vs. R could have helped here. But I did not
have enough confidence in my code, and did not want to give the 2 passers a two
high value ...
Thanks, to all the analysis of the position, which I actually had marked for
later analysis at home,
Dieter
