Yace shows exactly your line and a 0.0 score after a while. However, in such
positions, 0.0 can often be wrong. Note the the PVs end in kpppkr, a TB that has
been created by Eugene Nalimov. Last time I looked, it was not available anymore
on Bob Hyatt's ftp. The copy I had is also gone after a HD crash. With this TB
the analysis should be much more reliable.
Later c5 with positive score:
