+
+ * The build problems on sparc are still present due to the old

+ that is working on the the porter-boxes. This version is also the current
+ in testing and unstable. The build systems on lebrun should be updated.
+ * On ia64 the build fails with an: "internal compiler error" To prevent this
+ I will disable the profiling there. The g++ is now current here. The
+ behavior is different on the porterbox merulo. The plan is to report
+ upstream and test profiling in experimental next release again.

+Description of the universal chess interface (UCI) April 2006\r
+=================================================================\r
+\r
+* The specification is independent of the operating system. For Windows,\r
+ the engine is a normal exe file, either a console or "real" windows application.\r
+\r
+* all communication is done via standard input and output with text commands,\r
+\r
+* The engine should boot and wait for input from the GUI,\r
+ the engine should wait for the "isready" or "setoption" command to set up its internal parameters\r
+ as the boot process should be as quick as possible.\r
+\r
+* the engine must always be able to process input from stdin, even while thinking.\r
+\r
+* all command strings the engine receives will end with '\n',\r
+ also all commands the GUI receives should end with '\n',\r
+ Note: '\n' can be 0x0d or 0x0a0d or any combination depending on your OS.\r
+ If you use Engine and GUI in the same OS this should be no problem if you communicate in text mode,\r
+ but be aware of this when for example running a Linux engine in a Windows GUI.\r
+\r
+* arbitrary white space between tokens is allowed\r
+ Example: "debug on\n" and " debug on \n" and "\t debug \t \t\ton\t \n"\r
+ all set the debug mode of the engine on.\r
+\r
+* The engine will always be in forced mode which means it should never start calculating\r
+ or pondering without receiving a "go" command first.\r
+\r
+* Before the engine is asked to search on a position, there will always be a position command\r
+ to tell the engine about the current position.\r
+\r
+* by default all the opening book handling is done by the GUI,\r
+ but there is an option for the engine to use its own book ("OwnBook" option, see below)\r
+\r
+* if the engine or the GUI receives an unknown command or token it should just ignore it and try to\r
+ parse the rest of the string in this line.\r
+ Examples: "joho debug on\n" should switch the debug mode on given that joho is not defined,\r
+ "debug joho on\n" will be undefined however.\r
+\r
+* if the engine receives a command which is not supposed to come, for example "stop" when the engine is\r
+ not calculating, it should also just ignore it.\r
+ \r
+\r
+Move format:\r
+------------\r
+\r
+The move format is in long algebraic notation.\r
+A nullmove from the Engine to the GUI should be sent as 0000.\r
+Examples: e2e4, e7e5, e1g1 (white short castling), e7e8q (for promotion)\r
+\r
+\r
+\r
+GUI to engine:\r
+--------------\r
+\r
+These are all the command the engine gets from the interface.\r
+\r
+* uci\r
+ tell engine to use the uci (universal chess interface),\r
+ this will be sent once as a first command after program boot\r
+ to tell the engine to switch to uci mode.\r
+ After receiving the uci command the engine must identify itself with the "id" command\r
+ and send the "option" commands to tell the GUI which engine settings the engine supports if any.\r
+ After that the engine should send "uciok" to acknowledge the uci mode.\r
+ If no uciok is sent within a certain time period, the engine task will be killed by the GUI.\r
+\r
+* debug [ on | off ]\r
+ switch the debug mode of the engine on and off.\r
+ In debug mode the engine should send additional infos to the GUI, e.g. with the "info string" command,\r
+ to help debugging, e.g. the commands that the engine has received etc.\r
+ This mode should be switched off by default and this command can be sent\r
+ any time, also when the engine is thinking.\r
+\r
+* isready\r
+ this is used to synchronize the engine with the GUI. When the GUI has sent a command or\r
+ multiple commands that can take some time to complete,\r
+ this command can be used to wait for the engine to be ready again or\r
+ to ping the engine to find out if it is still alive.\r
+ E.g. this should be sent after setting the path to the tablebases as this can take some time.\r
+ This command is also required once before the engine is asked to do any search\r
+ to wait for the engine to finish initializing.\r
+ This command must always be answered with "readyok" and can be sent also when the engine is calculating\r
+ in which case the engine should also immediately answer with "readyok" without stopping the search.\r
+\r
+* setoption name <id> [value <x>]\r
+ this is sent to the engine when the user wants to change the internal parameters\r
+ of the engine. For the "button" type no value is needed.\r
+ One string will be sent for each parameter and this will only be sent when the engine is waiting.\r
+ The name and value of the option in <id> should not be case sensitive and can inlude spaces.\r
+ The substrings "value" and "name" should be avoided in <id> and <x> to allow unambiguous parsing,\r
+ for example do not use <name> = "draw value".\r
+ Here are some strings for the example below:\r
+ "setoption name Nullmove value true\n"\r
+ "setoption name Selectivity value 3\n"\r
+ "setoption name Style value Risky\n"\r
+ "setoption name Clear Hash\n"\r
+ "setoption name NalimovPath value c:\chess\tb\4;c:\chess\tb\5\n"\r
+\r
+* register\r
+ this is the command to try to register an engine or to tell the engine that registration\r
+ will be done later. This command should always be sent if the engine has sent "registration error"\r
+ at program startup.\r
+ The following tokens are allowed:\r
+ * later\r
+ the user doesn't want to register the engine now.\r
+ * name <x>\r
+ the engine should be registered with the name <x>\r
+ * code <y>\r
+ the engine should be registered with the code <y>\r
+ Example:\r
+ "register later"\r
+ "register name Stefan MK code 4359874324"\r
+\r
+* ucinewgame\r
+ this is sent to the engine when the next search (started with "position" and "go") will be from\r
+ a different game. This can be a new game the engine should play or a new game it should analyse but\r
+ also the next position from a testsuite with positions only.\r
+ If the GUI hasn't sent a "ucinewgame" before the first "position" command, the engine shouldn't\r
+ expect any further ucinewgame commands as the GUI is probably not supporting the ucinewgame command.\r
+ So the engine should not rely on this command even though all new GUIs should support it.\r
+ As the engine's reaction to "ucinewgame" can take some time the GUI should always send "isready"\r
+ after "ucinewgame" to wait for the engine to finish its operation.\r
+ \r
+* position [fen <fenstring> | startpos ] moves <move1> .... <movei>\r
+ set up the position described in fenstring on the internal board and\r
+ play the moves on the internal chess board.\r
+ if the game was played from the start position the string "startpos" will be sent\r
+ Note: no "new" command is needed. However, if this position is from a different game than\r
+ the last position sent to the engine, the GUI should have sent a "ucinewgame" inbetween.\r
+\r
+* go\r
+ start calculating on the current position set up with the "position" command.\r
+ There are a number of commands that can follow this command, all will be sent in the same string.\r
+ If one command is not sent its value should be interpreted as it would not influence the search.\r
+ * searchmoves <move1> .... <movei>\r
+ restrict search to this moves only\r
+ Example: After "position startpos" and "go infinite searchmoves e2e4 d2d4"\r
+ the engine should only search the two moves e2e4 and d2d4 in the initial position.\r
+ * ponder\r
+ start searching in pondering mode.\r
+ Do not exit the search in ponder mode, even if it's mate!\r
+ This means that the last move sent in in the position string is the ponder move.\r
+ The engine can do what it wants to do, but after a "ponderhit" command\r
+ it should execute the suggested move to ponder on. This means that the ponder move sent by\r
+ the GUI can be interpreted as a recommendation about which move to ponder. However, if the\r
+ engine decides to ponder on a different move, it should not display any mainlines as they are\r
+ likely to be misinterpreted by the GUI because the GUI expects the engine to ponder\r
+ on the suggested move.\r
+ * wtime <x>\r
+ white has x msec left on the clock\r
+ * btime <x>\r
+ black has x msec left on the clock\r
+ * winc <x>\r
+ white increment per move in mseconds if x > 0\r
+ * binc <x>\r
+ black increment per move in mseconds if x > 0\r
+ * movestogo <x>\r
+ there are x moves to the next time control,\r
+ this will only be sent if x > 0,\r
+ if you don't get this and get the wtime and btime it's sudden death\r
+ * depth <x>\r
+ search x plies only.\r
+ * nodes <x>\r
+ search x nodes only,\r
+ * mate <x>\r
+ search for a mate in x moves\r
+ * movetime <x>\r
+ search exactly x mseconds\r
+ * infinite\r
+ search until the "stop" command. Do not exit the search without being told so in this mode!\r
+ \r
+* stop\r
+ stop calculating as soon as possible,\r
+ don't forget the "bestmove" and possibly the "ponder" token when finishing the search\r
+\r
+* ponderhit\r
+ the user has played the expected move. This will be sent if the engine was told to ponder on the same move\r
+ the user has played. The engine should continue searching but switch from pondering to normal search.\r
+\r
+* quit\r
+ quit the program as soon as possible\r
+\r
+\r
+Engine to GUI:\r
+--------------\r
+\r
+* id\r
+ * name <x>\r
+ this must be sent after receiving the "uci" command to identify the engine,\r
+ e.g. "id name Shredder X.Y\n"\r
+ * author <x>\r
+ this must be sent after receiving the "uci" command to identify the engine,\r
+ e.g. "id author Stefan MK\n"\r
+\r
+* uciok\r
+ Must be sent after the id and optional options to tell the GUI that the engine\r
+ has sent all infos and is ready in uci mode.\r
+\r
+* readyok\r
+ This must be sent when the engine has received an "isready" command and has\r
+ processed all input and is ready to accept new commands now.\r
+ It is usually sent after a command that can take some time to be able to wait for the engine,\r
+ but it can be used anytime, even when the engine is searching,\r
+ and must always be answered with "isready".\r
+\r
+* bestmove <move1> [ ponder <move2> ]\r
+ the engine has stopped searching and found the move <move> best in this position.\r
+ the engine can send the move it likes to ponder on. The engine must not start pondering automatically.\r
+ this command must always be sent if the engine stops searching, also in pondering mode if there is a\r
+ "stop" command, so for every "go" command a "bestmove" command is needed!\r
+ Directly before that the engine should send a final "info" command with the final search information,\r
+ the the GUI has the complete statistics about the last search.\r
+\r
+* copyprotection\r
+ this is needed for copyprotected engines. After the uciok command the engine can tell the GUI,\r
+ that it will check the copy protection now. This is done by "copyprotection checking".\r
+ If the check is ok the engine should send "copyprotection ok", otherwise "copyprotection error".\r
+ If there is an error the engine should not function properly but should not quit alone.\r
+ If the engine reports "copyprotection error" the GUI should not use this engine\r
+ and display an error message instead!\r
+ The code in the engine can look like this\r
+ TellGUI("copyprotection checking\n");\r
+ // ... check the copy protection here ...\r
+ if(ok)\r
+ TellGUI("copyprotection ok\n");\r
+ else\r
+ TellGUI("copyprotection error\n");\r
+ \r
+* registration\r
+ this is needed for engines that need a username and/or a code to function with all features.\r
+ Analog to the "copyprotection" command the engine can send "registration checking"\r
+ after the uciok command followed by either "registration ok" or "registration error".\r
+ Also after every attempt to register the engine it should answer with "registration checking"\r
+ and then either "registration ok" or "registration error".\r
+ In contrast to the "copyprotection" command, the GUI can use the engine after the engine has\r
+ reported an error, but should inform the user that the engine is not properly registered\r
+ and might not use all its features.\r
+ In addition the GUI should offer to open a dialog to\r
+ enable registration of the engine. To try to register an engine the GUI can send\r
+ the "register" command.\r
+ The GUI has to always answer with the "register" command if the engine sends "registration error"\r
+ at engine startup (this can also be done with "register later")\r
+ and tell the user somehow that the engine is not registered.\r
+ This way the engine knows that the GUI can deal with the registration procedure and the user\r
+ will be informed that the engine is not properly registered.\r
+ \r
+* info\r
+ the engine wants to send information to the GUI. This should be done whenever one of the info has changed.\r
+ The engine can send only selected infos or multiple infos with one info command,\r
+ e.g. "info currmove e2e4 currmovenumber 1" or\r
+ "info depth 12 nodes 123456 nps 100000".\r
+ Also all infos belonging to the pv should be sent together\r
+ e.g. "info depth 2 score cp 214 time 1242 nodes 2124 nps 34928 pv e2e4 e7e5 g1f3"\r
+ I suggest to start sending "currmove", "currmovenumber", "currline" and "refutation" only after one second\r
+ to avoid too much traffic.\r
+ Additional info:\r
+ * depth <x>\r
+ search depth in plies\r
+ * seldepth <x>\r
+ selective search depth in plies,\r
+ if the engine sends seldepth there must also be a "depth" present in the same string.\r
+ * time <x>\r
+ the time searched in ms, this should be sent together with the pv.\r
+ * nodes <x>\r
+ x nodes searched, the engine should send this info regularly\r
+ * pv <move1> ... <movei>\r
+ the best line found\r
+ * multipv <num>\r
+ this for the multi pv mode.\r
+ for the best move/pv add "multipv 1" in the string when you send the pv.\r
+ in k-best mode always send all k variants in k strings together.\r
+ * score\r
+ * cp <x>\r
+ the score from the engine's point of view in centipawns.\r
+ * mate <y>\r
+ mate in y moves, not plies.\r
+ If the engine is getting mated use negative values for y.\r
+ * lowerbound\r
+ the score is just a lower bound.\r
+ * upperbound\r
+ the score is just an upper bound.\r
+ * currmove <move>\r
+ currently searching this move\r
+ * currmovenumber <x>\r
+ currently searching move number x, for the first move x should be 1 not 0.\r
+ * hashfull <x>\r
+ the hash is x permill full, the engine should send this info regularly\r
+ * nps <x>\r
+ x nodes per second searched, the engine should send this info regularly\r
+ * tbhits <x>\r
+ x positions where found in the endgame table bases\r
+ * sbhits <x>\r
+ x positions where found in the shredder endgame databases\r
+ * cpuload <x>\r
+ the cpu usage of the engine is x permill.\r
+ * string <str>\r
+ any string str which will be displayed be the engine,\r
+ if there is a string command the rest of the line will be interpreted as <str>.\r
+ * refutation <move1> <move2> ... <movei>\r
+ move <move1> is refuted by the line <move2> ... <movei>, i can be any number >= 1.\r
+ Example: after move d1h5 is searched, the engine can send\r
+ "info refutation d1h5 g6h5"\r
+ if g6h5 is the best answer after d1h5 or if g6h5 refutes the move d1h5.\r
+ if there is no refutation for d1h5 found, the engine should just send\r
+ "info refutation d1h5"\r
+ The engine should only send this if the option "UCI_ShowRefutations" is set to true.\r
+ * currline <cpunr> <move1> ... <movei>\r
+ this is the current line the engine is calculating. <cpunr> is the number of the cpu if\r
+ the engine is running on more than one cpu. <cpunr> = 1,2,3....\r
+ if the engine is just using one cpu, <cpunr> can be omitted.\r
+ If <cpunr> is greater than 1, always send all k lines in k strings together.\r
+ The engine should only send this if the option "UCI_ShowCurrLine" is set to true.\r
+ \r
+\r
+* option\r
+ This command tells the GUI which parameters can be changed in the engine.\r
+ This should be sent once at engine startup after the "uci" and the "id" commands\r
+ if any parameter can be changed in the engine.\r
+ The GUI should parse this and build a dialog for the user to change the settings.\r
+ Note that not every option needs to appear in this dialog as some options like\r
+ "Ponder", "UCI_AnalyseMode", etc. are better handled elsewhere or are set automatically.\r
+ If the user wants to change some settings, the GUI will send a "setoption" command to the engine.\r
+ Note that the GUI need not send the setoption command when starting the engine for every option if\r
+ it doesn't want to change the default value.\r
+ For all allowed combinations see the examples below,\r
+ as some combinations of this tokens don't make sense.\r
+ One string will be sent for each parameter.\r
+ * name <id>\r
+ The option has the name id.\r
+ Certain options have a fixed value for <id>, which means that the semantics of this option is fixed.\r
+ Usually those options should not be displayed in the normal engine options window of the GUI but\r
+ get a special treatment. "Pondering" for example should be set automatically when pondering is\r
+ enabled or disabled in the GUI options. The same for "UCI_AnalyseMode" which should also be set\r
+ automatically by the GUI. All those certain options have the prefix "UCI_" except for the\r
+ first 6 options below. If the GUI gets an unknown Option with the prefix "UCI_", it should just\r
+ ignore it and not display it in the engine's options dialog.\r
+ * <id> = Hash, type is spin\r
+ the value in MB for memory for hash tables can be changed,\r
+ this should be answered with the first "setoptions" command at program boot\r
+ if the engine has sent the appropriate "option name Hash" command,\r
+ which should be supported by all engines!\r
+ So the engine should use a very small hash first as default.\r
+ * <id> = NalimovPath, type string\r
+ this is the path on the hard disk to the Nalimov compressed format.\r
+ Multiple directories can be concatenated with ";"\r
+ * <id> = NalimovCache, type spin\r
+ this is the size in MB for the cache for the nalimov table bases\r
+ These last two options should also be present in the initial options exchange dialog\r
+ when the engine is booted if the engine supports it\r
+ * <id> = Ponder, type check\r
+ this means that the engine is able to ponder.\r
+ The GUI will send this whenever pondering is possible or not.\r
+ Note: The engine should not start pondering on its own if this is enabled, this option is only\r
+ needed because the engine might change its time management algorithm when pondering is allowed.\r
+ * <id> = OwnBook, type check\r
+ this means that the engine has its own book which is accessed by the engine itself.\r
+ if this is set, the engine takes care of the opening book and the GUI will never\r
+ execute a move out of its book for the engine. If this is set to false by the GUI,\r
+ the engine should not access its own book.\r
+ * <id> = MultiPV, type spin\r
+ the engine supports multi best line or k-best mode. the default value is 1\r
+ * <id> = UCI_ShowCurrLine, type check, should be false by default,\r
+ the engine can show the current line it is calculating. see "info currline" above.\r
+ * <id> = UCI_ShowRefutations, type check, should be false by default,\r
+ the engine can show a move and its refutation in a line. see "info refutations" above.\r
+ * <id> = UCI_LimitStrength, type check, should be false by default,\r
+ The engine is able to limit its strength to a specific Elo number,\r
+ This should always be implemented together with "UCI_Elo".\r
+ * <id> = UCI_Elo, type spin\r
+ The engine can limit its strength in Elo within this interval.\r
+ If UCI_LimitStrength is set to false, this value should be ignored.\r
+ If UCI_LimitStrength is set to true, the engine should play with this specific strength.\r
+ This should always be implemented together with "UCI_LimitStrength".\r
+ * <id> = UCI_AnalyseMode, type check\r
+ The engine wants to behave differently when analysing or playing a game.\r
+ For example when playing it can use some kind of learning.\r
+ This is set to false if the engine is playing a game, otherwise it is true.\r
+ * <id> = UCI_Opponent, type string\r
+ With this command the GUI can send the name, title, elo and if the engine is playing a human\r
+ or computer to the engine.\r
+ The format of the string has to be [GM|IM|FM|WGM|WIM|none] [<elo>|none] [computer|human] <name>\r
+ Examples:\r
+ "setoption name UCI_Opponent value GM 2800 human Gary Kasparov"\r
+ "setoption name UCI_Opponent value none none computer Shredder"\r
+ * <id> = UCI_EngineAbout, type string\r
+ With this command, the engine tells the GUI information about itself, for example a license text,\r
+ usually it doesn't make sense that the GUI changes this text with the setoption command.\r
+ Example:\r
+ "option name UCI_EngineAbout type string default Shredder by Stefan Meyer-Kahlen, see www.shredderchess.com"\r
+ * <id> = UCI_ShredderbasesPath, type string\r
+ this is either the path to the folder on the hard disk containing the Shredder endgame databases or\r
+ the path and filename of one Shredder endgame datbase.\r
+ * <id> = UCI_SetPositionValue, type string\r
+ the GUI can send this to the engine to tell the engine to use a certain value in centipawns from white's\r
+ point of view if evaluating this specifix position. \r
+ The string can have the formats:\r
+ <value> + <fen> | clear + <fen> | clearall\r
+ \r
+ * type <t>\r
+ The option has type t.\r
+ There are 5 different types of options the engine can send\r
+ * check\r
+ a checkbox that can either be true or false\r
+ * spin\r
+ a spin wheel that can be an integer in a certain range\r
+ * combo\r
+ a combo box that can have different predefined strings as a value\r
+ * button\r
+ a button that can be pressed to send a command to the engine\r
+ * string\r
+ a text field that has a string as a value,\r
+ an empty string has the value "<empty>"\r
+ * default <x>\r
+ the default value of this parameter is x\r
+ * min <x>\r
+ the minimum value of this parameter is x\r
+ * max <x>\r
+ the maximum value of this parameter is x\r
+ * var <x>\r
+ a predefined value of this parameter is x\r
+ Examples:\r
+ Here are 5 strings for each of the 5 possible types of options\r
+ "option name Nullmove type check default true\n"\r
+ "option name Selectivity type spin default 2 min 0 max 4\n"\r
+ "option name Style type combo default Normal var Solid var Normal var Risky\n"\r
+ "option name NalimovPath type string default c:\\n"\r
+ "option name Clear Hash type button\n"\r
+\r
+\r
+\r
+Examples:\r
+---------\r
+\r
+This is how the communication when the engine boots can look like:\r
+\r
+GUI engine\r
+\r
+// tell the engine to switch to UCI mode\r
+uci\r
+\r
+// engine identify \r
+ id name Shredder\r
+ id author Stefan MK\r
+\r
+// engine sends the options it can change\r
+// the engine can change the hash size from 1 to 128 MB\r
+ option name Hash type spin default 1 min 1 max 128\r
+\r
+// the engine supports Nalimov endgame tablebases\r
+ option name NalimovPath type string default <empty>\r
+ option name NalimovCache type spin default 1 min 1 max 32\r
+\r
+// the engine can switch off Nullmove and set the playing style\r
+ option name Nullmove type check default true\r
+ option name Style type combo default Normal var Solid var Normal var Risky\r
+\r
+// the engine has sent all parameters and is ready\r
+ uciok\r
+\r
+// Note: here the GUI can already send a "quit" command if it just wants to find out\r
+// details about the engine, so the engine should not initialize its internal\r
+// parameters before here.\r
+// now the GUI sets some values in the engine\r
+// set hash to 32 MB\r
+setoption name Hash value 32\r
+\r
+// init tbs\r
+setoption name NalimovCache value 1\r
+setoption name NalimovPath value d:\tb;c\tb\r
+\r
+// waiting for the engine to finish initializing\r
+// this command and the answer is required here!\r
+isready\r
+\r
+// engine has finished setting up the internal values\r
+ readyok\r
+\r
+// now we are ready to go\r
+\r
+// if the GUI is supporting it, tell the engine that is is\r
+// searching on a game that it hasn't searched on before\r
+ucinewgame\r
+\r
+// if the engine supports the "UCI_AnalyseMode" option and the next search is supposed to\r
+// be an analysis, the GUI should set "UCI_AnalyseMode" to true if it is currently\r
+// set to false with this engine\r
+setoption name UCI_AnalyseMode value true\r
+\r
+// tell the engine to search infinite from the start position after 1.e4 e5\r
+position startpos moves e2e4 e7e5\r
+go infinite\r
+\r
+// the engine starts sending infos about the search to the GUI\r
+// (only some examples are given)\r
+\r
+\r
+ info depth 1 seldepth 0\r
+ info score cp 13 depth 1 nodes 13 time 15 pv f1b5 \r
+ info depth 2 seldepth 2\r
+ info nps 15937\r

+ ....\r
+\r
+\r
+// here the user has seen enough and asks to stop the searching\r
+stop\r
+\r
+// the engine has finished searching and is sending the bestmove command\r
+// which is needed for every "go" command sent to tell the GUI\r
+// that the engine is ready again\r
+ bestmove g1f3 ponder d8f6\r
+\r
+\r
+\r
+Chess960\r
+========\r
+\r
+UCI could easily be extended to support Chess960 (also known as Fischer Random Chess).\r
+\r
+The engine has to tell the GUI that it is capable of playing Chess960 and the GUI has to tell\r
+the engine that is should play according to the Chess960 rules.\r
+This is done by the special engine option UCI_Chess960. If the engine knows about Chess960\r
+it should send the command 'option name UCI_Chess960 type check default false'\r
+to the GUI at program startup.\r
+Whenever a Chess960 game is played, the GUI should set this engine option to 'true'.\r
+\r
+Castling is different in Chess960 and the white king move when castling short is not always e1g1.\r
+A king move could both be the castling king move or just a normal king move.\r
+This is why castling moves are sent in the form king "takes" his own rook.\r
+Example: e1h1 for the white short castle move in the normal chess start position.\r
+\r
+In EPD and FEN position strings specifying the castle rights with w and q is not enough as\r
+there could be more than one rook on the right or left side of the king.\r
+This is why the castle rights are specified with the letter of the castle rook's line.\r
+Upper case letters for white's and lower case letters for black's castling rights.\r
+Example: The normal chess position would be:\r
+rnbqkbnr/pppppppp/8/8/8/8/PPPPPPPP/RNBQKBNR w AHah -\r

+.SH "NAME"
+stockfish \- free UCI chess engine, to calculate chess moves
+.SH "SYNOPSIS"
+.B stockfish
+.SH "DESCRIPTION"
+This manual page documents the
+.B stockfish
+command.
+.PP
+\fBstockfish\fP is an UCI chess engine, to calculate chess moves
+
+Stockfish is a free UCI chess engine derived from Glaurung 2.1. It is
+not a complete chess program, but requires some UCI compatible GUI
+(like XBoard with PolyGlot, eboard, Jose, Arena, in order to be used
+comfortably. Read the documentation for your GUI of choice for information
+about how to use Stockfish with your GUI.
+
+This version of Stockfish supports up to 8 CPUs, but has not been
+tested thoroughly with more than 2. The program tries to detect the
+number of CPUs on your computer and set the number of search threads
+accordingly, but please be aware that the detection is not always
+correct. It is therefore recommended to inspect the value of the
+"Threads" UCI parameter, and to make sure it equals the number of CPU
+cores on your computer. If you are using more than four threads, it
+is recommended to raise the value of "Minimum Split Depth" UCI parameter
+to 6.
+
+
+Opening book
+
+This version of stockfish has experimental support for PolyGlot opening
+books. For information about how to create such books, consult the
+PolyGlot documentation.
+
+.SH "OPTIONS"
+This program does NOT follow the usual GNU command line syntax, with long options starting with two dashes.
+.SH "SEE ALSO"
+Communication with UCI commands is documented by
+"The UCI Communication Protocol" in /usr/share/doc/stockfish/engine\-interface.txt.
+.SH "AUTHOR"
+stockfish was written by <Romstad Tord <tord@glaurungchess.com>> and Marco Costalba <mcostalba@gmail.com>.

+This manual page was written by Oliver Korff <ok@xynyx.de>,
+for the Debian project (but may be used by others).
