Version 10.12a: database of positions

Once again all changes in the development version 11 have been included in the version 10, except for new engines, and the support of Linux. 

Database of positions: 
  • Initially not included in this version.
  • With some improvements in relation to v9:
    • Import from pks files (G. Rajesh Ganesh)
    • Massive change of tags (Bernhard, peonpasado).
  • With the feedback of Benhard to fix bugs.



Engines:

  • McBrain 2.1.a is now the new default tutor. It is an adaptation of stockfish done by Michael Byrne

Bugs fixed:
  • Reading pgn files with blank lines (Ed Smith)
  • Crash when Komodo is the engine of a kibitzer (tico-tico)
  • Training Openings by repetition, the name of the training is by default the first opening selected. (rob)
  • In translations (and more) (Nils Andersson) (added transsiberian city labels to the translation)
  • Tourney, saving pgn, double blank line after a game (cja000)
  • A lot of little bugs (tico-tico, Alfonso).

  1. Hello Lucas. Great work. I love Lucas. Is it possible to make Lucas read or import more than one PGN files at the same time? That would be handy. Thank you

  2. Hi, sometimes when playing tourney elo the opponents clock hangs. It is always when he/she is in an unwinnable position with few pieces left on the board and time very short, say less than 30 seconds. Adjourning and restarting starts the clock again but after one second it hangs again. Eventually after starting and restarting enough times, only when there are a few seconds otherwise it just takes too long, it will give you a 'win on time' message. Bit frustrating and i actually lost once on time when the other clock was running ! only the once so not too worried, but the first error occurs at least 1 every 6 or 7 times the stated position is reached. Any help would be appreciated. Notwithstanding this complaint I love Lucas Chess.

    1. I need an example to replicate. There are several engines behind the personalities. A position and the name of a personality could serve me to try a replica.

  3. OK i will track the next instances and keep a log.

  4. Hi, this is an example of a hung file. It has hung with 24 seconds on Helen's clock.

    1. I have found the problem, in some situations the engine (greko) doesn't calc a correct move, and in that case the game must be assigned to the user, I have added this.
      Thank you very much.

  5. Is it possible to add an option to keep the tutor enabled, but not suggest a move? I'd like to have on-the-fly analysis of each move and its score, without having to tell the tutor to ignore its suggestion after every single move. If such an option exists, please point me to it. Thanks!

    1. You could disable the tutor, and use a kibitzer from Utilities menu.

  6. Thanks for your response. Unfortunately I find the kibitzer a bit distracting, and it doesn't rate my moves like a tutor does either. So if it is possible to add an option for a "silent tutor", one that scores all your moves without making any suggestions, it would be great. Thanks.

    1. But, an analysis at end of a game do the same work.

    2. Yes, that is what I use now. But it would really cool if it could happen real-time. This is just a suggestion, please disregard it if it is too much work.

    1. Menu Tools-PGN viewer-Read PGN and select the pgn file.
      Then Utilities-Create tactics

      Delete
  8. PGN Viewer imports only 999 puzzles, any way to get it increased?

    1. I need more info, I have imported now a file with 4000 games without problem.

      Delete
  9. Sorry, PGN Viewer loads PGN files even with 10K games. But When I create Tactics Training from Utilities Menu, it create tactics with 999 only.

    1. You can change this number (999) to the maximum.
