Chess, 18 point only

Note:
Our attempt at compatibility with Stanford was only 99%
successful.  If you use a blank space to indicate an
empty white square it will come out narrow due to
the stupidity of troff.
Either include the line
.br
	.cs ch 36
.br
to put yourself in constant spacing mode or else
use zero instead of space.
You should also set the vertical spacing to 18 points.
