Re: Can black save the game by 36...e4 or not?

Post by Eelco de Groot »

This was an endpoint in a possible PV from Rebel 15.1 last night, modified Rebel itself was also experimental only and just two hours old, it was a miracle that it even compiled, the first time with everything untested... But the backbone Rebel 15.1 Default is good of course. Then this 'end of PV' position was put to simmer with almost as new Crystallite overnight, one thread no tablebases. But I'm not sure it is a draw yet. Possibly the unequal coloured Bishops are evalled too high by Crystal's NNUE and the depths are not spectacular with this hardware on one thread. But fortress seems also not in sight, which is part of why I tried my newly downloaded Crystallite after Peter's rave review :)

Rebel's eval of unequal coloured Bishops seems lower (than Crystallite here), lower certainly than Rebel 14.1 who had very unrealistic eval of those endgames sometimes, if the NNUE had not seen them before so the NNUE had not been trained there, said Ed in his forum.

Debugging is twice as hard as writing the code in the first
place. Therefore, if you write the code as cleverly as possible, you
are, by definition, not smart enough to debug it.

SF plays out on its own drawn too. Same hardware, this time 30 threads and 8G hash for SF only at 30'+5" but not yet finished, keeping an +/- eval this time already up to move nr. 70, avoiding material reduction from both sides, don't know, how long I'll let it run this time, will show when it's over too, posting is getting rather long again already anyhow.

Guess Black can probably hold playing without blunders.
Seeing SF with White against ShashChess and at selfplay gives two more hints, why it evaluates the starting position so high. About 140 of 200 moves with +/= eval at the already dead endgame against ShashChess with the opposite coloured bishops is hard to watch, even if only post mortem.
ShashChess made it about 100 moves shorter at same endgame with White yet leastwise.

Edit: SF- selfplay's yet already over too:

I have the 42nd iteration from Rebel just in, on Uri's Deep Blue - Kasparov position. It is 1,84 for White, that is not bad if you think in the long run this is not a draw, possibly. But I have not a deep extension of the final position yet by Crystallite, so far it is going up and down a lot.

But this is Rebel's line, Shredder does not do move numbers in a FEN and Uri did not give them I think, but I have inserted them myself here in this line:
