|
|
.Ss Batch mode
|
|
Batch mode was intended for game tournaments where a referee program
|
|
handles the board display and pits one program against another.
|
|
In this mode,
|
|
.Nm
|
|
reads moves from standard input and writes its responses to standard
|
|
output.
|
|
The first line of input should be either
|
|
.Dq black
|
|
or
|
|
.Dq white
|
|
to specify whether
|
|
.Nm
|
|
has the first move or not respectively.
