Re: Stockfish based (ThothFishv1.0) Leela-Killer

I wonder how many rating points ThothFish1.0 leela-killer is losing against other engines or what is the result of it against stockfish that it is derived from it.

Re: Draws with Knight odds are possible against a top GM?

but given the zero for ten result I would imagine that the 2500 player at the 45' + 15" time limit would at least have a fairly competitive match at knight odds. Probably a top GM wouldn't give up more than an occasional draw at that level, but let's see how things stand a year or so from now. Yes,...

Re: Draws with Knight odds are possible against a top GM?

I think that it is interesting to see games and maybe humans can learn from it better how to play better with material disadvantage against other humans. I thought in the past that in the high level you can resign if you lose a piece and I remember that I tried some years ago to play with knight odd...

Re: Playing the endgame like a boss !!

I think that first step if you have an engine should be to a build a test suite from games of the engine when the engine does not find the right move. Testing a new patch should be done first in 1000 positions that the engine failed to find the right move. Examining positions and games to discover ...

Re: Playing the endgame like a boss !!

I do not know if NN are going to dominate but it is clear that stockfish goes in the wrong way and it is going to lose the first place. I believe that the way to test only by many games is not the correct way to continue to get better. I think that first step if you have an engine should be to a bui...

Re: Playing the endgame like a boss !!

I have seen Lc0 play in a style where it does not care how long it takes to mate. As long as it wins. And this makes perfect sense if your learned the game from ZERO. And all that matters is wins and losses and draw. You get no bonus for finding the shortest win. To fix this issue. I don't know if ...

Re: Playing the endgame like a boss !!

To me this is the most amazing thing about this Zero-business: that an engine with so many glaring weaknesses can be so good at winning actual games, by learning to avoid positions where its weaknesses would be tested. It demonstrates the more general principle that testing on game results (i.e. El...

Re: program to generare epd file of tactical exercises from pgn

I do not fully understand the conditions but if I understand correctly best move need to lead to advantage. I think that this condition is wrong and a position when there is only one move that is not losing also can be a tactical exercise. I think that what you basically need is not clearly winning ...
