If you want to use \ a larger book, you can configure DroidFish to use external polyglot \ or CTG book files:\n\ 1a. Copy one or more polyglot book files to the DroidFish directory on the SD card. \ Polyglot books must have the file extension .bin. Note! The Android file system is \ case sensitive, so the extension must be .bin, not .Bin or .BIN.\n\ 1b. Copy one or more CTG book files to the DroidFish directory. A CTG \ book consists of three files with file extensions .ctg, .ctb and .cto. \ You must copy all three files.\n\ 2. From the program menu, activate the Select opening book function.\n\ 3. Select the opening book file you want to use.\n\ \n\ PGN files\n\ DroidFish can load games from PGN files. To use this feature:\n\ 1. Copy one or more PGN files to the DroidFish/pgn directory on the SD card.\n\ 2. Long press the chess board and select Load game from PGN file.\n\ 3. Select the file, then the game within the file you want to load.\n\ \n\ To edit game headers such as player names, long press the move list and select \ Edit Headers. To edit comments for a move, long press the move list and \ select Edit Comments.\n\ \n\ To save your edited game, long press the chess board and select Save game to \ PGN file. Select the file to save to, then select the position in the file \ where the new game will be saved.\n\ \n\ To add computer analysis to the game tree, long press the analysis information \ when the computer is thinking and select Add Analysis. The current PV is \ added as a variation in the game tree.\n\ \n\ In analysis mode, it is possible to add null moves to the game tree. Be aware though \ that null moves are not included in the PGN standard and may not work in other PGN \ reading chess programs.\n\ \n\ Scid files\n\ If you have Scid on the go installed, you can read Scid database files \ directly from DroidFish. Long press the chess board and select Load game from \ Scid file.\n\ \n\ UCI engines\n\ DroidFish can use third party UCI engines. To use this feature:\n\ 1. Copy one or more UCI engine binaries to the DroidFish/uci directory on the SD card.\n\ 2. From the menu, choose Select Chess Engine and select the engine to use.\n\ \n\ License\n\ GNU GPL v3\n\ \n\ Developers\n\ * Stockfish is developed by Tord Romstad, Marco Costalba and Joona Kiiski.\n\ * Droidfish is developed by Peter Ă–sterlund.\n\ * User interface improvements by Aaro Korhonen.\n\ \n\ Translations\n\ * German translation by Uwe Walschus.\n\ * Spanish translation by Amador Cuesta.\n\ \ CPU Usage\n\ If you leave DroidFish running in the background and GameMode is set to \ Analysis or Computer vs Computer, or if Thinking Time \ is set to a large value, or if Pondering is enabled, DroidFish can use \ a lot of CPU power.\n\ \n\ If you are running on battery power, it is recommended that you change settings to \ conserve battery power, or that you exit DroidFish using the back button when \ you are not actively using the program.\ Offer Draw Queen Rook Bishop Knight Promote pawn to?
