The information I gave you were guesses abouit what goes wrong.
Someone who actually uses Emacs chess will perhaps know more accurate
what to do.

However what I guess from the information you gave is that you have
not installed Emacs chess as it should be installed. Maybe there is
some installation instructions that comes with it? Often those
instructions are a bit harder to follow on MS Windows since many of
those who have been writing things for Emacs are using GNU/Linux
instead and they do not know how to do the same things on MS Windows.

However let me guess a bit more. You could try doing

   M-: (require 'cl)

and then try Emacs chess again. (Normallly you should not do the
above, but it seems the easiest thing to try for you now.

The problem is a bit technical. "assert" is a function that is defined
in a part of Emacs, the cl library, that you normally do not see when
you run Emacs. That is because the library is used when byte compiling
Emacs lisp libraries files. When a file named for example foo.el
(Emacs lisp files has that extension) it is transformed into a foo.elc
where the addeed "c" means compiled. Emacs can use both .el files and
.elc files but uses the latter if it is available.

If there are instructions for installation I guess those installation
tells how to byte compile Emacs chess.
