SYNOPSIS¶

phalanx [options] [<moves> <minutes> [<increment in seconds>]]
phalanx [options] [<seconds per move>]
phalanx bench
phalanx bcreate [options]

DESCRIPTION¶

This manual page documents briefly the 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.

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.

It is also possible to run phalanx without xboard. Do phalanx -? to get a list of command line options. One important command of phalanx's ASCII interface is help.

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.
