No, you didn't misunderstand. It was exactly what I was looking for. Thanks for
both posts though. :-) I ran a few other engines on it, including the temerous
new Fritz 7.0.0.6 and it was still trying to find the answer after 10 minutes on
my Athlon 1 GHz, so it is a tough position for most engines I suspect. In fact
even after feeding it Rf7 and d1:Q both it and Junior 7 take time to see Nc6 for
example.
