test position that could happen in leela-sitbon game

This position could happen in case sitbon played 19...e5 and I am not sure if it is a draw or a win for black

Stockfish suggested Kf2 but I am not sure if it is the best move or maybe 20.Bd5 is better.

SF with 28 threads of 16x3.5GHz CPU won both of its matches with Black after 1.Kf2 against Lc0 with 3070ti GPU, did hold draw after 1.Bd5 with White and won this one game with Black too:

One game after 1.Bd5 transposed to 1.Kf2, the one of Lc0 playing 1.Bd5 with White, regards

I wonder how do you get tranposition after 20.Bd5
20.Bd5 Rd8 21.Bf3 e4 I see no tranposition to 20.Kf2 e4 or maybe Leela did not play 20...e4 after 20.Kf2 to allow stockfish to play later Bd5


In any case I continued the analysis and my stockfish still does not see 20.Bd5 but changed its mind to h4

Re: test position that could happen in leela-sitbon game

Post by Uri Blass »

After more than 12 hours again stockfish does not like the move 20.Bd5 for some reason so I will not continue and try to see what it say after 20.Bd5( I remember earlier it had evaluation of 0.91/51 for black after 20.Bd5 but did not save that analysis

To be honest, I don't see exactly how cb manages to merge two of the games, one after 1.Bd5 and one after 1.Kf2, to one as shown in .pgn above, the nearest to each other positions, after moves played in two of the games above, I see, are these:
20. Bd5 Rfd8 21. Bf3 Rf8 22. Kf2 e4 23. Bh5 f6 24. g6 c4 25. Ke3
and
20. Kf2 e4 21. Bh5 f6 22. g6 f5 23. g3 c4 24. Ke3

I trimmed the output of lower depths and outputs between depths for the sake of readibility. 20.- Be2 and 20.- h4 were preferred over 20.- Kf2 until depth 43 for the first time. WDL always shows 0% of predicted wins for white, but I was surprised that small changes in evals raised large differences in predicted draws and predicted loses for white. I stopped the analysis after depth 51 search was completed.

Then I'd have two more games, SF dev. played out on its own with 30 threads of the 4.3GHz CPU, 8G hash, 6men Syzgys, again one after 1.Kf2 and one after 1.Bd5, both 0-1:

The difference is that your pgn has 21. Bf3 Re8 22. Ke2 c4 23. Ke3 Bd3 24. h4 Rb6 when my atockfish's pv had 21. Bf3 Bd3

Iteration 54 was last time my pv had
20...Rfd8 21. Bf3 Re8 22. Ke2 c4 23. Ke3 Bd3 24.h4 but it seems stockfish had f5 and not Rb6 in that pv.

As well as 20.Kf2 or any other first (20th) move.
Two more games, that latest github- Reckless- compile played against SF dev., Reckless had Black each time and 30 threads of the 4.3GHz CPU, SF each time White and 30 threads of the 3.5GHz CPU, one time 1.(20.)Kf2 and one time 1.(20.)Bd5, both times 0-1 again.

Finally I'd say, Black wins that anyhow with best moves following, difference between 20.Kf2 and 20.Bd5 isn't big enough to speak about single best moves in classical meaning of a test position.
Did SF give too high evals in your latest example here

viewtopic.php?p=986526#p986526

it's simply evaluating winning chances of Black's too low this time at root- position in question, regards
Peter.
