I was a little surprised at the lack of chess resources for something
which came out of bell labs.  I'm not about to contribute an engine,
but I did end up writing this graphical program to help me keep track
of my correspondence games:

http://runjimmyrunrunyoufuckerrun.com/src/chessbd.tgz

It doesn't check moves or anything, but it can load, save, and play
back games.  It also accepts among its arguments a strict form of
portable game notation, so that you can, for example, run:

chessbd 1.e4 c5 2.c3 e6 3.d4 d5 4.exd5 exd5 \
5.Nf3 Bd6 6.Be3 c4 7.b3 cxb3 8.axb3 Ne7 \
9.Na3 Nbc6 10.Nb5 Bb8 11.Bd3 Bf5 12.c4 O-O \
13.Ra4 Qd7 14.Nc3 Bc7 15.Bxf5 Qxf5 16.Nh4 Qd7 \
17.O-O Rad8 18.Re1 Rfe8 19.c5 Ba5 20.Qd3 a6 \
21.h3 Bxc3 22.Qxc3 Nf5 23.Nxf5 Qxf5 24.Ra2 Re6 \
25.Rae2 Rde8 26.Qd2 f6 27.Qc3 h5 28.b4 R8e7 \
29.Kh1 g5 30.Kg1 g4 31.h4 Re4 32.Qb2 Na7 \
33.Qd2 R4e6 34.Qc1 Nb5 35.Qd2 Na3 36.Qd1 Kf7 \
37.Qb3 Nc4 38.Kh2 Re4 39.g3 Qf3 40.b5 a5 \
41.c6 f5 42.cxb7 Rxb7 43.Kg1 f4 44.gxf4 g3 \
45.Qd1 Rbe7 46.b6 gxf2 47.Rxf2 Qxd1 48.Rxd1 Rxe3 \
49.Rg2 Nxb6 50.Rg5 a4 51.Rxh5 a3 52.Rd2 Re2  0-1

then use the arrow keys to step through Kasparov's game against Deep
Thought (press down, then right repeatedly).

This is my first program in C, let alone for plan9, so any comments or
suggestions are most welcome,

Travis
