Chess-Artist is a very nice program to annotate PGN games. Annotate follows a different path, it stores and keeps the analysis results in a multi functional database, the Polyglot book format. The current main Polyglot book database contains over 51 million positions with the scores and depths from top engines and with that we can annotate (your) PGN games in a blink of an eye. Consider the immortal game of Anderssen vs Kieseritzky and the 3 output modes of Annotate.
Annotate PGN - Select a PGN, there after the Book Database and choose the output mode. For example select morphy.pgn and annotator.bin and all games of Morphy are stored in the folder pgn\output.pgn
Basically this is what the program is about, unless you want more, for instance:
Analyze and store your own games with any UCI engine to improve your play, a personal example.
Analyze and store the games of your favorite (or own) engine to improve its play.
Extend the current Book Database with more analyzed positions.
Create your own analyzed Book Database.
Analyze your own games or engine games
Make Analyzed Book - Select the PGN and wait till the engine menu arrives, manage the engine settings (see example) and when ready press "S". For example, select "ProDeo.pgn", press "S" and the Book Database "ProDeo.bin" will be created. Then run Annotate PGN and figure out where ProDeo 2.2 (or its opponent) went wrong.
Merge Books - Will merge 2 books into one, the output is always book.bin
Make Engine Book - Create a Book Database from annotated engine-engine matches (with depth and score). Example: select ccrl-3500.pgn (only 32 games), a book ccrl-3500.bin will be created and you are prompted to make an engine name selection. Type a part of the engine name (Stoc for Stockfish or Dragon for Komodo Dragon) is suffiecient to store all the scores and depths of that particular engine in the book. Type a * in case you want all games.
Make Player PGN - Create a specific Player PGN. For instance, create a PGN with the games of Kasparov from MillionBase 3.5, type Kasparov and kasparov.pgn will be created. Use the PGN (for instance) with Make Analyzed Book.
Make Players PGN - Does the same as above but for multiple players at the same
time. Consider the file players.txt in the root folder, 156 top players from the past and present. Using this function with MillionBase 3.5 will create a (large) PGN with the games these players played against each other. Example, in case you only want the games of Kasparov vs Karpov create a small players.txt file with only their names.
Find Position - also direct reachable via the [F3] function key is a powerful feature to 1) instantly find a position (as EPD taken from the clipboard) in the Book Database, 2) analyse this position with your favorite UCI chess engine (default is Stockfish 12) and 3) post the outcome on a (chess) forum with a simple copy&paste. Example. To configure (change) engines press [F1]. Note, if the position is not in the Book Database the annalysis and forum post functions still work.
Engine coding - With such a large Book Database (currently 51 million positions) analyzed by various engines it's important to classify each position. This is maintained in the text file engines.txt by giving each position a number. As one can see the Book Database mostly contains Stockfish 12 analysis. It's adviced after an analysis job (Make Analyzed Book and Make Engine Book) to code the new created book with the engine it has been analyzed with this function, the engine.txt will show up to make the decision easy. The engine code is used in the main function Annotate PGN to list the analysis engine. Positions without an engine code are listed with a * (star) only. Of course you are totally free to create your own Book Database with its own engine.txt file.
Book Statistics - Shows the internals of Book Database, the supplied 51 million Book Database as an example.
Remove Book voids - This option is reachable via the [F2] function key and weeds out zero weight book entries (see Book Statistics) in order to save disk space. Zero weight book entries are positions which are never played and thus unusable. A new book is create as books\new.bin.
Engine Configuration - select analysis engine, number of threads, hash table size.
Remove Book voids - remove positions that are not analyzed and thus have little value.
Find Position - copy a valid EPD in the clipboard and press [F3].
Online help - moves you to this page.
Quickly count the games in a PGN.
Create selected opening books - from a large PGN create a new PGN with the opening moves of your choice. For instance, create (or open) the textfile opening.txt and type: "e2e4 e7e5 g1f3 d7d6 ", save and press [F6] select the PGN and all the games of the Pirc-Defence are stored in opening.pgn
Create an analyzed Polyglot opening book from analyzed EPD files - as long as the EPD's are valid and contain the bm | ce and acd tags this will work. Press [F7] select the EPD and a corresponding Polyglot *.bin book is created, i.e. test.epd becomes test.bin.
Remove Blunders - remove obvious blunders from a Polyglot database. Based on the highest engine score remove those moves that score xx centipawns less. xx by default is set to 200 centipawns. For example: using a value of 50 will remove many moves (1.g4 | 1.b4 etc.) from the start position. A NEW.BIN database will be created without making changes to the original database, safety first.
Important - For Polyglot databases larger than 320Mb use the separate utility poly-blunders available in the download below. It can handle Polyglot books of 3Gb.
Remove Engines - Suppose your current Polyglot Database looks like this example and you want to remove the Houdini-6 analysis from the database. Type "3" and a NEW.BIN database will be created without the Houdini-6 analysis without making changes to the original database, safety first.
Rename Engines - Suppose your current Polyglot Database looks like this example and you want to combine the Stockfish 12 and Stockfish 13 analysis as one Stockfish. Type "10" (Stockfish 13) and thereafter "1" (Stockfish 12) and a NEW.BIN database will be created where the Stockfish 13 analysis is combined with the Stockfish 12 analysis. And of course without making changes to the original database, safety first.
Then do a "Book Statistic" from the menu and check if everything went to your expectation before you rename NEW.BIN.
Create opening sets for engine-engine testing. From a good PGN create flexible opening sets. Included in the Annotator-Basic version (download below) are 2 PGN's (gm-2600.pgn and gm-2700.pgn) with only games between 2600 and 2700 elo rated grandmasters. Press [F11], select the PGN and type the number of moves and a corresponding PGN opening set will be created. In the gm-2600 and gm-2700 folder are the 2-moves.pgn .... 10-moves.pgn already created. Examples [ 1 ] [ 2 ] [ 3 ]
Instead of a new large download only replace the old annotate.exe with the new one or download the basic version.
To update the main database annotator.bin run Merge Books from the menu and combine it with an update file, for instance players.bin (see the documentation above). Note that Merge Books takes considerable time to finish. A more easy way is to download the (below) latest updated version of annotator.bin and/or use it in combination with ProDeo Knowledge.
players.7z - contains the full games of 40 legendary players from Morphy till Carlsen analyzed with Stockfish 12 and since the recent release with Stockfish 13. In total 4 million positions.
gambits.7z - contains many unorthodox openings and gambits as listed on the Wikepedia. The purpose of these openings is that they hardly get attention in the standard books of engines but may serve as a starting point for correspondence chess. Books are created from MillionBase 3.45 and Correspondence 2.0 and are analyzed with Stockfish 13 at depth=20 about ~3300 elo.
regular.7z - contains popular openings played. Books are created from MillionBase 3.45 and Correspondence 2.0 and are analyzed with Stockfish 13 at depth=20 about ~3300 elo.
