Hello George,

This cannot be what you intended to write.  Chessmaster is not freeware.  Never
has been.  The King will never use tablebases outside of its native gui so there
is no tablebase issue with them

As you are using the Chessbase (Fritz et al) gui, setting the path to your
tablebase files once will enable all of the engines native to that gui to find
them.

Assuming that the freeware engines are UCI compatible - or are being run through
the appropriate adapter - then setting the path in the Fritz gui is sufficient.
Please be sure to check the box that says use tablebases.

It works for me over here...

Winboard engines that are being modified to run as UCI engines require the use
of Polyglot.  My advice is to do some more reading and start the tournament with
the UCI freeware engines first.  There are literally dozens of them out there.

Have some fun and then tinker around.  It really is not too difficult.  I did it
and if I can do it....

The tablebases (4 man)are about 30 mb total.  Drop them in a file on the C drive
(or wherever) and point to them thusly:

C:/TB

in Fritz.  No programming skills required.  I did it so it has to be really
simple...

I will yield to the experts here but I do not think that tablebases are going to
make a huge difference here.  I have seen experiments posted here that suggest
that tablebases are not going to make a meaningful elo difference (particularly
in the context of a basement tournament - that is not an insult, I run them all
the while!) so go ahead with or without.  It is up to you which way to go but
installing tablebases for use with chessbase products is simple and fast.


Have fun!


I hope this helped.


Later.
