I am not yet sure what happened.  I don't see how it could follow the Qc7 line
at all, as it knows it is not a good variation.  A puzzle at the moment, but I
have sent Graham a work-around to at least not get tricked like this again.  I
still wonder why it chose such a line, but I won't know until I see all the log
files from the tournament...
