The exact epd string that was in epd.epd was:

rnb4k/5r2/2p1p1Q1/pp3pP1/3P4/b2B1KP1/1PPB4/7R b - -

And the epd.out file was:

rnb4k/5r2/2p1p1Q1/pp3pP1/3P4/b2B1KP1/1PPB4/7R b - - acd 1; acn 1; acs 1; ce 0;
pv Rh7;


The analysis report can be found in my original post here.  This one puzzles me
too Bob but I could not rule out that its late <S>.  If you need any additional
info let me know.

Thanks
