  1. Congratulations on another alpha Lucas!!!

    Also a question to other users of LC:
    am i the only one that finds LucasElo very difficult in comparison to TourneyElo? In TourneyElo i have 1480 Elo and in LucasElo i'm stuck at 800 because i find Bikjump1 quite difficult to beat.

    Would be nice to hear from other users, that use both modes whether they also experience a large gap between the both.

    All the best Lucas!

    1. But to play against Bikjump1 is optional you could skip it.

    2. Jojo B,

      Run your games through analysis and have the tutor point out where mistakes are. Play over the training generated. I think you should step down 200 rating points on the opponent. (200 Points is a "step" in chess ratings - When you can win three in four games in a tournament at a "step" is when the soviet system would bump the pupils into the next grade. (This system was used at the most basic levels of organized chess - like a tournament between forms in school.)

    3. Jojo,

      TourneyElo is not running in a ply limited depth mode. It is limited by search depth. (Lucas feel free to jump in if I am mistaken.)
      Ply depth is simply a way of saying the number of moves I can consider in depth. One ply means I consider the consequences of my move and your move only. Five thousand positions a second means I am scoring five thousand possible positions based on an algorithm. (Five moves deep in any position is trivial.)
      Previous versions of Lucas Chess can be bled out into a very weak program by playing a sophisticated opening and making the computer use all the thinking time to get to speed. When the endgame is reached the computer is caught between the time management and weakening algorithms and the bottom falls out.

  2. Thank you very much, Lucas. Very appreciated!

    Ando liado últimamente, pero tengo otro carro de propuestas para hacerte. Ya te daré la brasa. Un saludo!!

  3. very good program
    with a bug: winboard chess program don't working on my pc...

    1. It is not a bug, Lucas Chess only supports UCI engines.

    2. ok, I wanted you to say that I was able to run some winboard programs using wb2uci...
      Now with this version don't work...
