Ant winboard version is also old.

What is your estimate for the level
of Celes relative to the winboard engines
in Leo's tournament?

Is it better than the public Ant?

Baron is clearly better than the winboard Ant but
It was not clear for me if it was better than
the last Ant.

The point is that they repeated the same opening after losing
and in both games the queen got from d8 to d5 and d6 and d8.

I know that there is an opening 1.e4 d5 2.exd5 Qxd5
3.Nc3 Qd6 but even if this opening is good
it seemed from the games that Ant did not know to play
it so it is a clearly bad choice for opening book.

If I participate I participate with unreleased version
to prevent preperations but I do not plan to participate with untested version.

I do not believe in the importance of books and the
success of List with no book convince me that a book
is not very important.

I believe that something with similiar level to list4.61
that is unknown with no book or a very small book
has good chances to get 50%.

My latest movei(not public) has book and pondering
but my tests are almost always with no book when
I always change the
first move so I can get different games.
