XPostScript Chess Font -- "README" file.

XRestrictions on Use:
X------------ -- ----
X    You must keep the copyright notice on this file and on the
Xaccompanying "Font" file.  If you change anything, you must clearly
Xmark your changes.  Otherwise, you may use these files as you please
Xfor private, educational or research purposes.  You may also use them
Xfreely for commercial purposes as long as you do not make any changes
Xto the shapes of the pieces without my approval.
X
X    I do not, and am in no position to, make any claim as to
Xsuitability of these files for any specific purpose.  They work for
Xme, and if they work for you too I shall be pleased.  If they do not
Xwork for you, well, you have what you paid for.
X
X    If you are pleased with the results, please let me [and your
Xreaders, if any!] know.  If you manage to make money out of them,
Xplease let me know how!  I'd quite like to see [real or PostScript]
Xcopies of what you manage to do, if you have the necessary time,
Xinclination and resources.
X
X    If you don't like the results, please let me know why.  Indeed,
Xif you have any comments, please e- or snail- mail them to me.
X
XWhat you have to do:
X---- --- ---- -- ---
X    You should have three files, called "Font", "Demo" and "Table".
XIf you have a way of viewing PostScript, shovel "Font" and "Demo" or
X"Font" and "Table" at it;  for example, I use the commands
X
X        lpr -Plwriter Font Demo
X        lpr -Plwriter Font Table
X
Xto see the results on "my" LaserWriter.  If you have no way of viewing
XPostScript, then I'm sorry, but I can't help you.  What you should see
Xis an assorted collection of boards and figurines in various sizes and
Xrotations ("Demo") or a neat table showing all the symbols in the font
X("Table").  If anything else happens, you will have to consult someone
Xwho knows what they're doing -- *not* me!  I can promise you that the
Xfiles as shipped print nicely on a bog-standard Apple LW+.  They take
Xseveral minutes each to print on our LW+;  this is largely because they
Xmake almost pessimal use of the font caching mechanism -- lots of big
Xcharacters are printed once each in different sizes and orientations.
XConventional pages with lots of figurines or ordinary text and only a
Xfew diagrams print acceptably quickly (especially, of course, if you
Xhave a faster or more recent LW).
X
X    If you are happy with the demos, you can then install the "Font"
Xfile as a font in your system.
X
X    ****************************************
X    * I cannot help you with this process! *
X    ****************************************
X
XI can't even do it for our own computer, which has a much-hacked (from
Xits PDP-11 days) version of Troff;  I leave it to our guru.  Neither
Xhe nor I know what magic you have to utter for an unhacked Troff, or
Xfor TEX, or for Macs or PCs or whatever weird and wonderful software
Xor hardware you possess.  When you install the font, you may also find
Xit useful to grab some of the PostScript code from "Demo", especially
Xif you want to draw (for example) labelled diagrams.
X
XWhat there is in the Font:
X---- ----- -- -- --- -----
X    There are really two fonts wrapped up into one.  The more
Xconventional sub-font is the so-called "text mode", and is what you
Xget when you first select the font.  This mode itself has two major
Xcomponents.  The upper case letters are the figurines, for use in
Xtext.  For example, "Q" draws a queen figurine.  Lower case letters
Xand other symbols are (most of) the Informant symbols (omitting only
Xsymbols like "?" and "ch" that you can reasonably expect to find in
Xboring old Times Roman, but including "+" and "-").  I've been as
Xmnemonic as I could, but there are just too many symbols.
X
X    The other sub-font is "diagram mode".  In this, upper case
Xletters draw white pieces, and lower case letters draw black pieces.
XFor example, "Knk" draws a white king adjacent to a black knight
Xand a black king.  The pieces include a selection of fairy pieces
Xand other related symbols -- everything I've seen or had reported
Xto me on chess diagrams in the last few years.  The other symbols
Xin this sub-font consist of board-drawing components and motions
Xto facilitate the construction of diagrams.  You switch between
Xtext and diagram modes using the prime symbol, "'".  For example,
Xthe famous Reti study can be diagrammed by the PostScript:
X
X        ('#[7K;8;k1P;7p;8;8;8;8]') show
X
Xwhere "#" draws the board, and the stuff between "[...]" is the
Xconventional Forsythe notation for the position.  Obviously, for
Xpractical use, you will need a chess pre-processor (which I have
X*not* written!).
X
X    Most of the capabilities of the font are illustrated on
Xthe demo page, which also includes some possibly-useful PostScript
Xprocedures for various of the effects.
X
X    Warning:  the dual-mode font treads on very thin ice in
Xsome places!  In particular, the caching mechanisms of PostScript
Xare very easy to fool with a dynamic font of this type.  For example,
Xfinding the width of a string is fraught with danger;  do it only
Xwith strings that include matched pairs of primes.
X
XThe font design:
X--- ---- -------
X    There are surprisingly many different chess fonts in use in
Xprinted books.  I have tried to copy the simplest -- for example,
Xthe rooks have no brickwork, and the kings are quite plain.  Note
Xthat the pieces do not scale well.  Large pieces (inches high) for
Xposters, etc., will have to be specially designed (and are usually
Xbased on "real" Staunton pieces).  Tiny pieces suffer from the lack
Xof resolution on 300 dpi (or coarser) printers.  On a 300 dpi printer,
X7-point is really too small, anything less is hopeless (see the demo).
XI usually use 15-point, which is comparable with most books.
X
X    The hardest piece to get right is the knight.  The book designs
Xare hopeless at 300 dpi resolution, as there are too many fine lines
Xaround the mouth and chin.  Any attempts to copy them just look like a
Xcaricature.  So I've made it a bit chunkier.  Most readers don't notice.
X
X    Note that most of the pieces (as opposed to the figurines)
Xcannot be cached.  This is because they include both write-white and
Xwrite-black components (partly, but not entirely, because they have
Xto work on black squares);  this makes drawing a whole page of black
Xkings (or whatever) rather slooow.  Fortunately, you don't often need
Xsuch a thing.  The figurines *are* cached, so are the Informant symbols,
Xand so are the commonest pieces (the black squares, and the pawns of
Xboth colours).
X
XForeign usage:
X------- ------
X    Foreign users may want to re-assign the letters used for the
Xvarious pieces.  This can easily be done in the Font file.  Lines
Xsuch as
X
X    dup 8#113 /WK put        % 'K'
X
X(not too far down the file) signify that ASCII character 113 (octal), or
X"K", is to draw the White King.  If you want some other character to draw
Xthe WK, alter the 113 to match.  You will have to change the BK and Kfig
Xby the same amount, and you will also have to reassign whatever symbol
Xyour chosen character already draws, if any.  Another minor problem is
Xthat some of the fairy pieces are defined explicitly in terms of the
Xexisting pieces -- eg, if you decide to use "F" to draw White queens,
Xthen the procedure for Grasshoppers (look for "WG" in Font) must be
Xchanged to draw upside-down "F" instead of upside-down "Q".  I hope the
Xnecessary edits are obvious even to non-PostScript users.  I suggest that
Xafter any change you try the Table and Demo files again.
X
XUnusual chess pieces:
X------- ----- -------
X    I've included a fair number of pieces that may not be familiar to
Xall chess players.  These include:
X    F for fou, French version of bishop.  There are several designs
X        of fou in print, I have selected the easiest to implement.  If
X        you want one of the others, you'll have to write it yourself.
X    D,X for draughts pieces.  Note that these are not cached (except
X        as figurines);  if you are writing a book on draughts with
X        lots of diagrams, you might find it worthwhile to re-write
X        them in a cachable way.  This is easier if you want to use
X        them on the white squares (you don't need the "halo" effect),
X        but the books I have seen are about equally split on this.
X    C,I,T for chameleon, imitator, rose.  Various fairy pieces.
X    E,G,L,M,O,S,U,V,Z for various rotated standard pieces, used in
X        fairy chess.  Note that the "Demo" file includes a more
X        general way to rotate a piece.  I have used S for nightrider,
X        oppositely to the problemists convention which uses S for
X        knight and N for nightrider;  there is no way that the average
X        player is going to change his habits!  If you are a problemist,
X        feel free to interchange S and N (and then M and Z).
X    .,@,|,_ for various other marks useful in annotating diagrams.
X        See the "Demo" file for examples of their use.
X    A,H,J,W,Y are unused.  Feel free to use them to add new pieces.
X
XGo pieces:
X-- -------
X    Sorry, despite several requests, I haven't put these in.  I
Xcan't save the whole world in one easy lesson.  The pieces themselves
Xand the board are easy in PostScript;  the annotations and the necessary
Xpre-processor are another kettle of fish.  The Go stones could also be
Xused for Reversi (Othello).
X
XBridge symbols:
X------ --------
X    No-one has actually asked for these, but just to forestall you,
Xnote that they are already provided in many places -- symbol fonts,
Xdingbats fonts, Hershey fonts, ....
X
XFinal comments:
X----- ---------
X    Suggestions for improvements, especially in the PostScript,
Xwill be welcomed.  Especially if they improve portability (which I
Xcan't check locally!).  Especially if you've tried them yourself,
Xand can vouch that they work.  Suggestions for extra symbols (other
Xthan Go or Bridge) also welcomed, especially if accompanied by
XPostScript or other descriptions of their shape.

X.SH DESCRIPTION
X.I Gnuchess
Xplays a game of chess against the user or it plays against itself.
X.PP
X.I Gnuchess
Xis an updated version of the gnuchess program.
XIt has a simple alpha-numeric board display, an IBM PC compatible interface,
Xor it can be compiled for use with the
X.B chesstool
Xprogram on a SUN workstation or with the
X.B xboard
Xprogram under X-windows.
XThe program gets its opening moves from the file
X.B gnuchess2.book
Xwhich is  located in a directory specified in the makefile.
XTo invoke the program type:
X.TP
X.B gnuchess
X- curses based version
X.TP
X.B gnuchessn
X- IBM PC character set based version
X.TP
X.B gnuchessr
X- ASCII based version
X.TP
X.B gnuchessc
X- chesstools compatible version
X.TP
X.B gnuchessx
X- xboard compatible version
X.SH TIME CONTROLS
X.PP
XIf one argument is given and it begins with a
X.B :
Xthen it is the search time per move in seconds.
XIf it has no
X.B :
Xit is the search depth in plys.
XSo
X.B gnuchess :30
Xwill generate 1 move every 30 seconds, while
X.B gnuchess 5
Xwill search each move to depth 5.
X
XIf two or more arguments are given, they will be used to set tournament
Xtime controls with the first argument of each pair being the number of moves and the second
Xbeing the total clock time in minutes[
X.B :
Xseconds].  Thus, entering
X.B gnuchess 60 5
Xwill set
Xthe clocks for 5 minutes (300 seconds) for the first 60 moves,
Xand
X.B gnuchess 30 3:30
Xwill allow 3 minutes and 30 seconds for 30 moves.
X
X.B gnuchess 30 5 1 :30
Xwill allow 5 minutes for the first 30 moves and 30 seconds for each move after that.
XUp to 4 pairs of controls may be specified.
X
XIf no argument is given the program will prompt the user for level of play.
X
XFor use with
X.B chesstool
Xor
X.B xboard
X, see the documentation on those programs.
X.SH BOOK
X.PP
XThe book
X.I gnuchess.book
Xconsists of a sequence of openings.
XAn opening begins with a card starting with a
X.B !
X, the rest of the card is comments.
XFollowing this is a series of moves in algebraic notation alternating white
Xand black separated by white space. A move may have a
X.B ?
Xafter it indicating this move should never be made in this position.
XMoves are stored as position:move so transpositions between openings
Xcan take place.
X.SH HASHFILE
X.PP
XThe hashfile if created should be on the order of 4 megabytes or
X.B gnuchess -c 22.
XThis file contains positions and moves learned from previous games.
XIf a hashfile is used the computer makes use of the experience it
Xgained in past games. Tests run so far show that it plays no worse
Xwith the hashfile than without, but it is not clear yet whether
Xit provides a real advantage.
X.SH LEGAL MOVES
X.PP
X.B Note:
XPiece letters and legal castling notation is determined by the language file.
XWhat is specified here is the default english.
X.PP
XOnce
X.I gnuchess
Xis invoked, the program will display the board and prompt the user
Xfor a move. To enter a move, use the notation
X.B e2e4
Xwhere the first letter-number pair indicates the origination square
Xand the second letter-number pair indicates the destination square.
XAn alternative is to use the notation
X.B nf3
Xwhere the first letter indicates the piece type (p,n,b,r,q,k).
XTo castle, type the origin and destination squares
Xof the king just as you would do for a regular move, or type
X.B o-o
Xor
X.B 0-0
Xfor kingside castling and
X.B o-o-o
Xor
X.B 0-0-0
Xfor queenside.  To promote a pawn append the type of the new piece to the move, as in
X.B e7e8q
Xor
X.B c7c8r.
X.SH "FUNCTION LETTERS"
X.TP
X.B -L lang
XUse language
X.I lang from the file
X.B gnuchess.lang.
XIf -L is not specified it uses the first language in the file.

X.TP
X.B -t
XShow statistics for HASHFILE
X.TP
X.B -c size
XCreate a new HASHFILE. File size is 2^size bytes.
X.TP
X.B -s pathname

X.SH COMMANDS
X.PP
XIn addition to legal moves, the following commands are available as responses.
X.BNote:
X command names are determined by the
X.Ilanguage
Xfile and may vary with the implementation. This is default english.
X.PP
X.B alg
X-- allow algrbraic input (not implemented)
X.PP
X.B Awindow
X-- change Alpha window (default score + 90)
X.PP
X.B Bwindow
X-- change Beta window (default score - 90)
X.PP
X.B beep
X-- causes the program to beep after each move.
X.PP
X.B bd
X-- updates the current board position on the display.
X.PP
X.B book
X-- turns off use of the opening library.
X.PP
X.B both
X-- causes the computer to play both sides of a chess game.
X.PP
X.B black
X-- causes the computer to take the white pieces, if the computer is to move first the
X.B go
Xcommand must be given.
X.PP
X.B coords
X-- show coordinates on the display (visual only)
X.PP
X.B contempt
X-- allows the value of
X.I contempt
Xto be modified.
X.PP
X.B debug
X--  asks for a piece as color piece, as wb or bn, and shows its calculated value on
Xeach square.(allowed only on visual versions)
X.PP
X.B debuglevel
X--  sets level of debugging output if compiled with debug options.
X.PP
X.B depth
X-- allows the user to change the
Xsearch depth of the program.  The maximum depth is 29 ply.
XNormally the depth is set to 29 and the computer terminates
Xits search based on elapsed time rather than depth.
XUsing the depth command allows setting depth to say
X4 ply and setting response time to a large number such as
X9999 seconds. The program will then search until all moves
Xhave been examined to a depth of 4 ply (with extensions up
Xto 11 additional ply for sequences of checks and captures).
X.PP
X.B easy
X-- toggles easy mode (thinking on opponents time)
Xon and off. The default is easy mode ON.  If easy mode is disabled,
Xthe keyboard is polled for input every so often and when input is
Xseen the search is terminated. It may also be terminated with a
X.Isigint.
X.PP
X.B edit
X-- allows the user to set up a board position.
X
X.B     #
X- command will clear the board.
X
X.B     c
X- toggle piece color.
X
X.B     .
X- command will exit setup mode.
X
X.B    pb3
X- place a pawn on b3
X
XPieces are entered by typing a letter (p,n,b,r,q,k) for
Xthe piece followed by the coordinate.
X
XThe usual warning about the
X.I language file
Xapplys.
X.PP
X.B exit
X-- exits gnuchess.
X.PP
X.B first
X-- tells the computer to move first. Computer begins searching for a move.
X(same as "go").
X.PP
X.B force
X-- allows the user to enter moves for both
Xsides. To get the program to play after a sequence of moves
Xhas been entered use the 'white' or 'black' commands.
X.PP
X.B get
X-- retrieves a game from disk.  The program will
Xprompt the user for a file name.
X.PP
X.B hash
X-- use/don't use hashfile.
X.PP
X.B hashdepth
X-- allows the user to change the minimum depth for using the hashfile and the number of moves from the
Xbegining of the game to use it.
X.PP
X.B help
X-- displays a short description of the commands and the current status of options.
X.PP
X.B go
X-- tells the computer to move first. Computer begins searching for a move.
X(same as "first").
X.PP
X.B hint
X-- causes the program to supply the user with its predicted move.
X.PP
X.B level
X-- allows the user to set time controls such as
X60 moves in 5 minutes etc.  In tournament mode, the program will
Xvary the time it takes for each
Xmove depending on the situation.  If easy mode is disabled (using
Xthe 'easy' command), the program
Xwill often respond with its move immediately, saving time on
Xits clock for use later on.
X.PP
X.B list
X-- writes the game moves and some statistics
Xon search depth, nodes, and time to the file 'chess.lst'.
X.PP
X.B material
X-- toggle material flag - draws on no pawns and both sides < rook
X.PP
X.B new
X-- starts a new game.
X.PP
X.B p
X-- evaluates the board and shows the point score for each piece. The total score for
Xa position is the sum of these individual piece scores.(allowed only on visual versions)
X.PP
X.B post
X-- causes the program to display the principle
Xvariation and the score during the search.  A score of
X100 is equivalent to a 1 pawn advantage for the computer.
X.PP
X.B quit
X-- exits the game.
X.PP
X.B random
X-- causes the program to randomize its move
Xselection slightly.
X.PP
X.B rcptr
X-- set recapture mode.
X.PP
X.B remove
X-- backout the last level for both sides. Equal to 2
X.I undo's.
X.PP

X-- performs some speed tests for MoveList and CaptureList generation, and ScorePosition position scoring
Xfor the current board.
X.PP
X.B time
X-- set computers time remaining, intended for synchronizing clocks among multiple players.
X.PP
X.B undo
X-- undoes the last move whether it was the computer's
Xor the human's. You may also type "remove". This is equivalent
Xto two "undo's" (e.g. retract one move for each side).
X.PP
X.B white
X-- causes the computer to take the black pieces, if the computer is to move first the
XiB go
Xcommand must be given.
X.PP
X.B xget
