  1. Hi.
    In the tournament between engines, can i show the difference of materials? If yes, how?
    Thank you. Ciao.

  2. Hi Giovanni, pressing Alt-C by example.

  3. Hi, excuse for my questions....
    How can I activate the Kibitzer, after that I download a PGN?
    If I go to the menu Utility->Kibitzer and I choose an Engine,
    nothing happens....

    1. This is the way. It must be a problem with tha kibitzer. File bug.kibitzer has the information, if not bug.log.

    2. I have tried again the old version 11.00.20a and the Kibitzer worked fine.
      With last version Kibitzer does not work. There is only the file bug.log containing the string "Version 11.00.21".
      Hi and thank you.

    3. Giovanni, please send me the file UsrData\moscas.pkv, to lukasmonk at gmail, to test.

  4. Hi.
    During a tournament between chess engines:
    1) The "Cancel" button at top/left does not work (i must kill the process to exit);
    2) The difference of materials (ALT+C) is not updated in real time but I must press ALT+C twice to see the current materials.
    Thank you.

  5. The old version Lucas 11.00.20 was working, with the latest version of Lucas 11.00.21 impossible to move a part (under Windows 10). Would it be possible to include in an upcoming version of Lucas an opening report as in the Scid vs Pc chess program, see the video on youtube in French of ChessMI, the video it calls "Bénéficiez de toute une vie de GMI pour construire votre répertoire d'ouvertures! "

  6. hi Lucas. how to convert GM .xgm files pgn or fns format or cbh format

Setting analysis parameters

Since version 2.04, you can change the parameters used by the program to determine whether a move is good or bad and also the elo calculated for an analyzed game. The parameters are as follows: limit_score Default value: 2000 Minimum value: 1000 Maximum value: 4000 Data type: integer Determines the score in centipawns from which the position is considered to be totally won, that the probability of winning is 100%. curve_degree Default value: 50 Minimum value: 1 Maximum value: 100 Data type: decimal percentage Expresses the correlation between the score in centipawns and the probability of winning/losing. It associates -limit_score with 0 and +limit_score with 100. Curve formula created based in  python-chess/Engine/Score/wdl    difmate_inaccuracy Default value: 3 Minimum value: 1 Maximum value: 99 Data type: integer If the difference between the best move and the move made means going
