"Very simple endgame positions" where it fails. :lol: Meanwhile, SF from 1.5 years ago + 6-men got 99.999% of 7-men positions right with a few Gnodes. Some sample of the very natural and common positions where it failed in Aloril's testing : 1K6/5b2/8/3k4/b4B2/2B5/3r4/8 b - - 0 1 Fails to see that ...

Maybe you are right for latest stockfish but people showed that some older version found the win. Stockfish and all top programs can find easily the loss after 2.Bc7 The main problem is finding 2.Bc7 because stockfish insist to use the null move pruning. I wonder how much time we need to wait for s...

Talking about "perfect chess" or 32 piece TBs is like talking about aliens or similar. We have next to no data to analyze any of these things. Given that Stockfish plays far from perfect chess (very strong is still far from perfect, just as 7 piece tablebases are exponentially far away from 32 piec...

If there were no opening book, Stockfish will be minimally able to draw another Stockfish or Leela in 95% of games. If Stockfish is playing against 32 men TB, the extreme condition would be 50 draw 50 losses , which is within 200 elo. On the other hand, current Stockfish with contempt may be slight...

I suppose it is buggy. Or poorly tuned. No amount of features is going to help if you have poor heuristic evaluation. It just makes the engine more clever in finding ways to do itself in. Micro-Max / Fairy-Max has ~1950 Elo CCRL, and hardly has any features at all. Not even full MVV-LVA sorting. Th...

Sure, that is what "taking it into account when evaluating a position" means, right? My conjecture was that this would decrease their playing strength, though. So the 'good ones' are probably not as good as they could have been. I think that the problem is that the 50 move rule does not happen very...

You have a set of 1000 moves that you need to memorize in the opening in different positions. You want to learn as much as possible in an hour by spaced repetition. I wonder if there is a research what is the best way to do it when the instructions what to do is by a chess program and if it is possi...
