Hi Keith,

well, I just looked for the UCI options in the EXE (of course also with a
hex editor), and a few bytes after these names there are some numbers which
seemed to be what I´ve searched for. ;-)
So the ´trick´ is just a bit experience, some guessing and/or luck, and the
last thing is trying if it works ...

But as I wrote in my follow-up: unfortunately this has the side-effect of also
changing the MultiPV default value, so it wasn´t really a good idea.

Regards,
Franz.
