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. As one can see the Book Database mostly contains Stockfish 12 analysis. This is maintained in the text file engines.txt by giving each position a number. Make Players PGN - Does the same as above but for multiple players at the sameĮngine coding - With such a large Book Database (currently 51 million positions) analyzed by various engines it's important to classify each position. Use the PGN (for instance) with Make Analyzed Book. For instance, create a PGN with the games of Kasparov from MillionBase 3.5, type Kasparov and kasparov.pgn will be created. Make Player PGN - Create a specific Player PGN. 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. 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. Make Engine Book - Create a Book Database from annotated engine-engine matches (with depth and score). Merge Books - Will merge 2 books into one, the output is always book.bin
Then run Annotate PGN and figure out where ProDeo 2.2 (or its opponent) went wrong. For example, select "ProDeo.pgn", press " S" and the Book Database "ProDeo.bin" will be created. Make Analyzed Book - Select the PGN and wait till the engine menu arrives, manage the engine settings (see example) and when ready press " S".
