I only played Hiarcs7.32 at 60'/60. I don't have the PV window opened, but it

in "analyse game", I analysed some games with Hiarcs7.32 at 10 sec a move to see
if it could spot some deep tactical mistakes I Knew took Hiarcs7.32 many minutes
to find in a normal search. It was able to spot the mistakes, and show the
correct move in its analysis.
