.TH PHALANX "6" "January 2008" "Phalanx XXII"
.SH NAME
Phalanx \- Chess playing program
.SH SYNOPSIS
.B phalanx
[\fIoptions\fR] [\fI<moves> <minutes> \fR[\fI<increment in seconds>\fR]]
.br
.B phalanx
[\fIoptions\fR] [\fI<seconds per move>\fR]

.SH DESCRIPTION
This manual page documents briefly the
.BR phalanx
program.
This manual page was written for the Debian GNU/Linux distribution
(but may be used by others), because the original program does not
have a manual page.
.PP
.B phalanx
is a chess playing program. It is partially xboard compatible. Under
xboard, it can play games, force & undo moves, and show thinking. In
this version, you cannot set positions with xboard.
.PP
It is also possible to run phalanx without xboard. Do
.B phalanx -?
to get a list of command line options. One important command of
phalanx's ASCII interface is
.B help.
.PP
.B phalanx
uses (traditional) 10x12 board implementation. There are three often
used board implementations: "8x8" (GNU Chess), "bitboard" (Crafty), and
"10x12" (Nimzo, Phalanx). In short, "10x12" is easy to implement and the
code is small (==fast on PC). Opening book is small, simple,
hand-written.

assistance of

and then edited slightly to clean it up. Modified by Marco Pessotto.
