Glaurung Mainz does no real pruning, but my latest development version
uses a very primitive form of static null move pruning in the last two plies.
This is a very recent addition, implemented one of the last few days before
Christmas.  During the holiday, I played my longest ever self-play match:
A 1920 game match played from the 960 different FRC starting positions.
The version with static null move pruning won by 1034-886 against a
similar version without static null move pruning.

And also:

3) My current version is quite different from Glaurung Mainz.

I am not quite sure.  I have never participated before, and frankly I
find on-line events to be a bit boring.  Perhaps I will be there, but
I probably won't know until a few days before the start of the
tournament

I really don't want to do that.  If I cannot be there myself and chat
with the other programmers, there is just no point.  Besides, it
would make the tournament less interesting for the other
participants.  I know I would be disappointed if I operated my
program and faced an opponent not operated by its author.
