PgnScanner is a console mode tool that can process PGN files. It can read chess games and interpret the content of the included textual comments in order to extract some useful informations. If the used format is not too specific, the data of time, depth and evaluation generated by chess engines can be recognized. PgnScanner can also make some recognitions and detections on each position of the analyzed game. When a game is matching one of the selection's criteria, it can be saved in a EPD or PGN file. PgnScanner can also calculate the players elo ratings and rebuild tournaments grid in text or html format (except swiss tournament).
accbook.dll is a Windows dynamic library that allows your engine to read pgnscanner's books by adding less than 10 lines in your program. PgnScanner and accbook.dll are provided as free without guarantee of any kind.
