Well, I followed the advise given above.
However, my observation still holds true.
Once out of the ``book'' gnuchess refuses to play quickly.
It takes forever to make a move, no matter what the time
control is set at.

And as for it playing badly, well, when I had the patience to
complete a game, I beat it! And that doesn't happen very often!

Also, the depth of search never goes above 2+, while gnuchess
on a Sun server, with the same time control, often goes to
5...

Yes, I do have the pl62 version.

One thought: Could the machine's RAM memory have anything to
do with gnuchess' slowness? I think our machine has only 8MB
of RAM, and even though I am the only person using it, there
are always 3 or 4 windows open plus a PS viewer and a calendar...
But why would it work very fast when making the first few
moves and then die all of a sudden?
