I am working on chess.c for Unix, the one that starts like this:
/*
    C source for CHESS               Rev. 3-10-87

    Written by John Stanback (hplabs!hpfcla!hpisla!hpltca!jhs)

    Patches for BSD Unix by Rich Salz (rs@mirror.TMC.COM) - 5/3/87
                  and Bill Randle (billr@tekred.TEK.COM) - 5/22/87
*/

I think there is a bug in this program; perhaps someone could comfirm
this.  The program will not let you castle sometimes when you should
be allowed to.

For example, try this:
Make the file chess.opn read like this

Alekine Defense
e2e4  g8f6
e4e5  f6d5
c2c4  d5b6
d2d4  d7d6
f2f4  d6e5
f4e5  b8c6
c1e3  c8f5
b1c3  e7e6
g1f3  f8e7
f1d3  o-o
!

With this being the only opening line in the book, you can proceed with
white as follows
d3f5  b6c4  <-- on level 1, computer will probably play this
f5h7  g8h8
d1d3  c4e3
d3e3  h8h7
o-o
except that chess will not let you play o-o.
Any comments?
