I am training endgames using Lucas Chess and playing the position from FEN against Stockfish. But sometimes I would like to have engines play the position with itself. I can achieve this in Lucas Chess easilly with 'Engine Tournament'. But the problem is that there is a FEN position, in 3 moves the evaluation goes to -3 for black and the match ends because engine resigns.

I would like to force engine to play itself till the very end so I can see the plan used to win the ending. I can of course use additional program and make a move suggested by it (eg. Scid with Stockfish too) but I would like it better to have only one program used. Is there any setting for an engine that can force it?

  • The GUI forces resignation, and I don't see a way to turn it off... – SmallChess Oct 18 '16 at 11:33
  • Maybe any other GUI? But I would like straight answer, do not have time to install 20 of them ;( – Chlebik Oct 18 '16 at 11:35
  • I'm sure Chessbase doesn't resign for me. – SmallChess Oct 18 '16 at 11:36
  • But simple ChessBase Reader got that functionality? And I do not mean that engine resigns when playing me - I mean when engine plays against engine. – Chlebik Oct 18 '16 at 12:25
  • Not sure. Someone else may be able to answer your question. – SmallChess Oct 18 '16 at 12:25

It's possible, but you'll may need to update the source code.

In https://github.com/lukasmonk/lucaschess/blob/843be9f57baa3f631c05181b1012df844f53c84b/Code/QT/PantallaEntMaq.py

    # Resign
    lbResign = Controles.LB2P(self, _("Resign/draw by engine"))
    liResign = ((_("Very early"), -100),
                (_("Early"), -300),
                (_("Average"), -500),
                (_("Late"), -800),
                (_("Very late"), -1000),
                (_("Never"), -9999999))
    self.cbResign = Controles.CB(self, liResign, -800)

The GUI will resign if the score goes below 800 cp. You can do this:

self.cbResign = Controles.CB(self, liResign, -9999999)

This will disable auto resign for the software.

Chess engines will play till checkmate :) Only GUIs can be set to give up face to indefensible positions (+10 for B, or -10 for W). ARENA, for example, can be set to play till K's death.
