SOMU
Some Of My Utils
version 1.7a
SOMU is a command line utility operated by the arrow keys. It contains several PGN and EPD tools. PGN files are found (stored) in the PGN folder, likewise EPD files in the EPD folder. It's functions:
The PGN part
Match Stats | From a PGN create and (automatically) view a HTML file, example-1 is created from gambit.pgn (provided in the download) taken from the YAT gambit tournament. Example-2 is created from a CCRL pgn testing Komodo 12. |
Match Compare | Check the PGN of an engine-engine PLY-Match, games should be indentical else perhaps something is wrong. Different moves are marked and stored in OUTPUT.PGN Background: it's extremely important (especially for starters) that a PLY-MATCH (say PLY=10) produces the exact same reverse game, so game-1 and game-2 in the PGN should be 100% equal, game-3 = game-4 and so on. |
Cross-table | This function will create a cross table from a (large) PGN file. Maximum number of players (human and/or engine) is 100. Example taken from the gambit.pgn mentioned earlier. Another example, the final FCP rating list by Frank Quisinsky. |
Strip PGN | Strip played moves by engines from a PGN. What is left and stored in OUTPUT.PGN are the book moves. Handy for opening book tuning with Polyglot. |
Split PGN | Split large PGN files into smaller parts. |
Remove Double Openings (games) | From a PGN collection display the match score, then remove the double openings and calculate the new match score without the double openings. This util is handy in 3 ways: . checking an eng-eng match for opening doubles, see screenshot (file bf.pgn) . pre-checking your predefined opening sets for eng-eng matches. . In case a PGN doesn't contain comments it will check for duplicated games. |
The EPD part | |
Remove Doubles | Remove doubles from an EPD collection. |
EPD legal check | Remove invalid positions from an EPD collection. |
EPD to PGN | Converts EPD to PGN, bm and ce tags included when present. Try this with the included 150 positions example.epd file. |
Split EPD | Split large EPD files into smaller parts. |
Prepare EPD | Create an EPD collection from PGN games for the use of Analyze EPD, Analyze EPD++ or Analyze EPD+++. With the option "Ply from" - "Ply till" you can hack the analysis job into pieces. Doubles are removed. |
Analyze EPD | |
Analyze EPD ++ | Analyze an EPD collection with Stockfish 8, 9 and higher splitting the analyzing over a user defined number of threads for speed reasons. Example before and after. The advantage of Analyze EPD and Analyze EPD ++ is that it will work with every new version provided the Stockfish team doesn't change the bench function. Just copy a newer Stockfish version in the SOMU folder. Current default version is SF10x a beta version considerable stronger than SF9, see results. |
Analyze EPD +++ | |
