+ PolyGlot as adapter and book engine
PolyGlot is a "UCI adapter". It connects a GUI interface (such as
XBoard, Winboard, Arena or Chessbase) to a UCI chess engine.
By specifying an opening book (in PolyGlot book format) chess engines
can transparently use such books.
- PolyGlot understands the two main GUI protocols: UCI and xboard. Nor-
- mally the protocol will be auto detected but this can be overridden in
- the configuration file.
+ PolyGlot understands the two main GUI protocols: UCI and xboard.
+ Normally the protocol will be auto detected but this can be overridden
+ in the configuration file.
In xboard mode PolyGlot fully translates between the xboard and UCI
protocols. In addition it tries to solve known problems with other
engine and vice versa, except that it will play book moves on behalf of
the engine when the occasion arises.
- The engine options are exported as UCI options in UCI mode and as "fea-
- ture option=" commands in xboard mode. The latter form an extension of
- the xboard protocol as defined by H.G. Muller.

+ of the xboard protocol as defined by H.G. Muller.
Options which normally appear in the [PolyGlot] section of the config
file (see below) are exported as options with their name prefixed by

+ furthermore it can merge two such binary books into a third one.
PolyGlot can also extract some useful information from PolyGlot books.
The utility "dump-book" dumps the "lines" in a book for a given color.
- By definition a line is a sequence of moves (from the starting posi-
- tion) in which the given color makes only book moves and the other

Since a PolyGlot book is built up from positions and not lines there
Due to the possibility of transpositions this is not a fool proof
method.

In epd test mode, PolyGlot will search positions in an epd file and

A perft count is the number of legal move sequence in a given position

- ever much slower than other more dedicated programs.

PolyGlot supports the following options
-pgn (default: "book.pgn")
When invoked as

PolyGlot supports the following options
-in1
When invoked as
- polyglot dump-book

PolyGlot supports the following options
-bin (default: book.bin)
When invoked as
- polyglot info-book

+ polyglot info-book
PolyGlot supports the following options
-bin (default: book.bin)
Input file in PolyGlot book format.
-exact
- Attempt to count the provably unreachable positions among the iso-
- lated ones. Note that this takes a very long time.

+ isolated ones. Note that this takes a very long time.
When invoked as

(possibly with a config file as first argument) PolyGlot supports
besides the generic options described above the following additional
options.
When invoked as
- polyglot perft
-
+ polyglot perft
PolyGlot supports the following options
-fen (default: starting position)
The characters "#" and ";" serve as comment characters.
- By default initial and final white space is stripped from option val-
- ues. If you want to avoid this, or if you want use one of the comment
- characters # or ; in option values (such as for NalimovPath), enclose
- the value in quotes.
-
- [PolyGlot] section
+ Initial and final white space is stripped from option names and values.
+ If you need to use characters which have a special meaning to PolyGlot
+ (these are ';#[]=\') you should quote them by preceding them with '\'.
+ "Quoting" other characters in this way has no effect. In particular the
+ use of '\' as a path separator in windows should normally not affected.
+ [PolyGlot] section
This section is used by PolyGlot only. The engine is unaware of these
options. The list of available options is detailed below.
EngineCommand
Put here the name of the engine executable file. You can also add
command-line arguments. Path searching is used and the current
- directory will be "EngineDir".
+ directory will be "EngineDir". On Linux the EngineCommand is passed
+ to wordexp so that shell quoting rules and expansions are applied.
+ On Windows the EngineCommand is simply passed to CreateProcess
+ which does its own shell like processing.
SettingsDir (default: $HOME/.polyglot on Linux; ".\_PG" on Windows)
The directory where ini files are stored for engines that are
move are ignored.
ResignScore (default: 600)
- This is the score in centipawns that will trigger resign "count-
- ing".
+ This is the score in centipawns that will trigger resign
+ "counting".
ShowPonder (default: true)
Show search information during engine pondering. Turning this off

KibitzCommand (default: "tellall")
- xboard command to use for kibitzing, normally "tellall" for kibitz-
- ing or "tellothers" for whispering.
+ xboard command to use for kibitzing, normally "tellall" for
+ kibitzing or "tellothers" for whispering.
KibitzDelay (default: 5)
How many seconds to wait before starting kibitzing. This has an
BookFile (default: book.bin)
The name of the (binary) book file. Note that PolyGlot will look
for it in the directory it was launched from, not in the engine
- directory. Of course, full path can be used in which case the cur-
- rent directory does not matter.
+ directory. Of course, full path can be used in which case the
+ current directory does not matter.
BookRandom (default: true)
Select moves according to their weights in the book. If false the
If true then PolyGlot restricts the options it sends to those that
are potentially useful for WinBoard.
- Work arounds
-
+ Work arounds
Work arounds are identical to options except that they should be used
only when necessary. Their purpose is to try to hide problems with
various software (not just engines).
- IMPORTANT: Any of these work arounds might be removed in future ver-
- sions of PolyGlot. You are strongly recommended to contact the author
- of faulty software and truly fix the problem.

PolyGlot supports the following work arounds:
CanPonder (default: false)
PolyGlot now conforms to the documented UCI behaviour: the engine
will be allowed to ponder only if it (the engine) declares the
- "Ponder" UCI option. However some engines which can actually pon-
- der do not declare the option. This work around lets PolyGlot know
- that they can ponder.

+ ponder do not declare the option. This work around lets PolyGlot

SyncStop (default: false)
- When a ponder miss occurs, Polyglot interrupts the engine and IMME-
- DIATELY launches a new search. While there should be no problem
- with this, some engines seem confused and corrupt their search
- board. "SyncStop" forces PolyGlot to wait for the (now useless)
- ponder search to finish before launching the new search.

PromoteWorkAround (default: false)
Some engines do not specify a promotion piece, e.g. they send
to the way kibitzing is implemented, KibitzMove is disabled in that
case.

them, but sends the information to the engine at startup (converted to
UCI form). You can add any UCI option that makes sense to the engine

.IX Subsection "PolyGlot as adapter and book engine"
PolyGlot is a \*(L"\s-1UCI\s0 adapter\*(R". It connects a \s-1GUI\s0 interface (such as
XBoard, Winboard, Arena or Chessbase) to a \s-1UCI\s0 chess engine.

.IX Subsection "Book making utilities"
PolyGlot supports the \*(L"PolyGlot opening book format\*(R". This is the
defacto standard non-proprietary opening book format. It is fully documented
Roughly speaking a PolyGlot opening book is a collection of triples
(position, move, weight). A \*(L"position\*(R" is represented by a 64\-bit
Zobrist hash key. The weight is proportional to the probability the move should

Other opening book formats such as ChessBase's .ctg format and Arena's
\&.abk format are undocumented and proprietary. They can only be used
-by their own GUIs.
+by their own GUIs.
.PP
PolyGlot can compile a pgn file into a binary PolyGlot book and furthermore
it can merge two such binary books into a third one.
.PP
PolyGlot can also extract some useful information from PolyGlot books. The utility

+\&\*(L"dump-book\*(R" dumps the \*(L"lines\*(R" in a book for a given color. By definition
a line is a sequence of moves (from the starting position) in which
the given color makes only book moves and the other color makes
arbitrary moves (i.e. not necessarily book moves).
Since a PolyGlot book is built up from positions and not lines there
may be (and there usually are) many positions in the book that are not
on a \*(L"line\*(R" as defined in the previous paragraph. It is convenient
-to call such positions \*(L"isolated\*(R" positions. The utility \*(L"info\-book\*(R"

counts such isolated positions.
.PP
Some of the isolated positions are provably unreachable and they
utility info-book will attempt to count the isolated positions which
require a player to make a non-book move when a book move is available.
Due to the possibility of transpositions this is not a fool proof method.
