Development version 11.00.19: Director changed

Bugs fixed:

  • Order in analysis when score is over 10000 centipawns. (Max Aloyau)
  • Transsiberian, automatic save doesn't include Date field (Pedro José)
  • Challenge 101, bad score when time used is less than 5.0 secs. (Max Aloyau)
  • Transiberian, level 2, error in a tactic. (David Parkin)


  • Database added two tools to change the order of registers (TheIgnobleSavage)
  • Updated McBrain to version 2.7
  • Director:
    • Main change: graphic elements are added directly on the main board.
    • After saving a position the added elements are visible from any other board.
    • It is possible to change the file that has the information, which can facilitate sharing with other users.
    • Can be added text in a blackboard.
    • Activated with F1..F10.
    • A simbol appears in the board when the position has info.

11.00.19 -> 11.00.19a: bug fixed in the panel of results to Compete-Singular moves-Calculate your strength (thanks to Max Aloyau)


  1. Please a WinBoard/XBoard Protocols also the Engine log in Lucas Chess like arena GUI in Lucas Chess..

    1. I take note of both suggestions, I have many doubts about the first one.

  2. Fantastic chess program! Will definitely recommend...I'd like to use an external engine as a tutor. Is this possible? I checked an FAQ but it doesn't seem possible as the options when selecting the tutor are limited.

    1. Option Tools-Engines-External Engines, to add an external engine.
      Then Options-Configuration-Tutor, an select the external engine.
      The external engine must have the MultiPV option.

  3. In the Personal Openings Guide it would be useful to go up and down moves with the arrow keys instead of having to click on the move and then use the arrow buttons. Otherwise good upgrade :)

  4. Hi.
    Lucas Chess is FANTASTIC !!!!!
    But I have some doubts about ELO Performances, in analisys game.
    In the following game of mine, White (me) has a performance of 2648 Elo and Black has a performance of 3018!!!
    But the problem of an overestimation is for all my games.
    I remember that Carlsen has an ELO of 2800.
    I have done the analisys with MCbrain 2.7.
    What is the reality?
    Thank you.

    1. The elo calculated depends on the time used for analysis. The longer, the more accurate. With 10 seconds per movement McBrain has calculated that the black elo is 2855 in my pc. It is only a relative measure. Maintain this level, against different users is not easy.

  5. Is there a way in Personal Openings Guide to make a training for a specific line? Whenever I click training it makes a training session for the main line but I can't work out how to do it for any other lines I'm interested in training with

    1. Not at the moment. This is a long overdue issue, I haven't found the time to work on it.
