19       GNU Go plays a game of Go against the user. It has many other features:
20       it can play against itself or another program, analyse and score a
21       recorded game. GNU Go is compliant with Go modem protocol, load and
22       save game in the Smart Game format.
23
24       GNU Go default is a simple alpha-numeric board display, but you can use
25       a client such as CCGGoobbaann.

29       Go is a game of strategy between two players usually played on a 19x19
30       grid called ggoobbaann. The two players put black and white ssttoonneess on the
31       goban to enclose tteerrrriittoorryy. Go was invented about 4000 years ago in
32       ancient China. Other names for this game are (Chinese) WWeeii CChhii,
33       (Korean) BBaadduukk and (Ing) GGooee.

37       To start a game with default options, just invoke "gnugo". The board
38       will be drawn at your terminal using ASCII letters.  In this mode, you
39       can get help on available commands by the hh key.  To play as Black with
40       4 stones handicap, with a 0.5 komi, recording the game in the file
41       record.sgf:
42
43        gnugo --color black --handicap 4 --komi 0.5 -o record.sgf

48       CGoban is a general purpose client program by Bill Shubert for playing
49       Go. It runs under X Window System with a beautiful resizeable graphic
50       display. To use GNU Go under X Window System, obtain the most recent
51       version of CGoban from Bill Shubert's web site
52
53       http://www.igoweb.org/~wms/comp/cgoban/index.html
54
55       Start CGoban. When the CGoban Control panel comes up, select `Go
56       Modem.'  You will get the Go Modem Protocol Setup. Choose one (or both)
57       of the players to be ``Program,'' and fill out the box to the path to
58       gnugo. After clicking OK, you get the Game Setup window. Choose ``Rules
59       Set'' to be Japanese (otherwise handicaps won't work). Set the board
60       size and handicap if you want. Click OK and you are ready to go.
61
62       In the Go Modem Protocol Setup window, when you specify the path to GNU
63       Go, you can give it command line options, such as --quiet to suppress
64       most messages. Since the Go Modem Protocol preempts standard I/O, other
65       messages are sent to stderr, even if they are not error messages. These
66       will appear in the terminal from which you started CGoban.

69
70       The game stops when both players pass. GNU Go will attempt to compute
71       and report the score to you. It may occasionally make mistakes due to
72       wrong evaluation of the status of a group. You can check the score as
73       follows. In ASCII mode, at the end of the game, stones believed dead
74       are marked in lower case letters, and you have the option of toggling
75       their status before counting.  Using CGoban, you may use CGoban's
76       counting facility to count the game using either Japanese or Chinese
77       rules.

81       gnugo --ll filename.sgf --mode ascii
82
83       loads filename.sgf and lets you navigate through the game by using the
84       commands forward, back, goto and last.  It is not possible to navigate
85       through variations in ascii mode.  You may also use CGoban to view
86       stored games. CGoban can navigate variations.

90       The files in the doc directory contain detailed documentation about
91       debugging options and internal program structure. Other documentation

96       The Go Modem Protocol is a standard interface between Go programs and
97       graphical display.
98
99       The Go Modem Protocol was developed by Bruce Wilcox with input from
100       David Fotland, Anders Kierulf and others. Any Go program *should* use
101       this protocol since it is standard. Since CGoban supports this proto‐
102       col, the user interface for any Go program can be done entirely through
103       CGoban. Using the Go Modem Protocol, you can play with another computer
104       running a different program (even on a different operating system)
105       using a modem, a serial cable or over the internet if the other program
106       also supports the protocol. You can also communicate with the Go
107       servers using CGoban.

111       Games (with comments, variations and other features) can be stored in
112       the Smart Game Format (SGF). This format originated in Anders Kierulf's
113       program Smart Go. Martin Muller and Arno Hollosi developed the current
114       standard, which may be found at
115
116       http://www.red-bean.com/sgf/
117
118       GNU Go supports the Smart Game Format.
