  3. Hey Lucas, just recently found your software and it looks really helpful, especially creating training files from my own blunders/mistakes. But I'm having trouble getting that aspect of it to work.

    What I'd like to do is create a training file from several games, but I can't get it to work. I've loaded my games into a database, then I go into that database and into utilities and create tactics training but no matter if I have 1 game or several games highlighted it asks me to name the file and then shows a percentage bar at 2% or 5% but it never moves from there. I've left it running for hours just to see with no results.

    What am I doing wrong? I've looked through configuration to see if I haven't set something up but I can't find anything, and I've gone through the documentation that I could find on Lucas Chess' website but not finding a solution. Can you assist?

    1. Send me example data to lukasmonk at gmail, this is more easy to analyze the problem.

  4. Automatic save of games in transsiberian do not include 'date' field.

  5. I think i found a bug, after playing 200 of the learn tactics by repetition, checkmates from the FCIS database, attacking the king in castle m2-m7. It crashed out of the trainer and I had to delete that session and start over. Is this an issue or do you always have to start over after exiting?

    1. Perhaps it is a bug of the program, but it is very difficult to know which is the problem. I´ll study the way used to save results to do it more often.

    2. I should also add that prior to crashing it started having issues moving to the next puzzle after correcting solving the current position. This started around puzzle 196.
      Thank you for the excellent program Lucas.
