Is the position in the first post the correct one? Bh3 loses to g3, so I wouldn't expect an engine to prefer it over other similar losing moves.
If the king was on f1, Bh3 would be the only drawing move. With this position 8/8/8/5bk1/8/5B2/6PP/5K2 b - - 0 1 then Slow 2.9 does prefer Bh3, 0.0 with 5-man TB, but without any TBs an inaccurate 3.35 for white score.
I removed the wrong-colored bishop knowledge from my chess program to simplify it, but it is interesting to see some positions like the one in Uri's post where it would help.
Black to play and Draw, which engine can solve this Puzzle ?

Re: Not Too Many Engines Without EGTB Pick The Correct Bh3! Sac
The problem is that without EGTB 99% of the engines after Bh3! will take the Bishop since they only calculate up to 29 to 30 moves deep and do NOT see a win for White, which is what is required to see that g3 will win for White, but when all other moves lose to White anyway, Bh3! has the best chance of drawing since 99% of engines are too materialistic and will take the Bishop after calculating only up to probably 20 moves at the most.jonkr wrote: ↑Fri Jun 24, 2022 8:44 am [fen]8/8/8/5bk1/8/5B2/6PP/6K1 b - - 0 1[/fen]

Re: Black to play and Draw, which engine can solve this Puzzle ?
The latest version of SlowChess that I found dated 1 Jun 2022 also play Bh3! hoping for the last chance of drawing but it does NOT take the Bishop which is the correct reply, but the mojority of the other engines are too materialistic and take the Bishop

Re: Black to play and Draw, which engine can solve this Puzzle ?
[quote=Chessqueen post_id=928736 time=1656062970 user_id=10732]
The latest version of SlowChess 2.9 that I found dated 1 Jun 2022 also play Bh3! hoping for the last chance of drawing since 90% of the engines above 3450 still believe that after taking the Bishop on h3 that they will win, it took Ethereal up to move 460 to realize that it was NOT winning with a score of 5.64 . WOW a total of 471 , this is why it is so hard for 90% engine of the engines to figures out that White will not win after taking the Bishop Sac without using EGTB, and when testers test engines they are not really testing the strength of the engines when they are using EGTB greater than 3-4-5 pieces, because the programmers use their precious time to add endgame knowledge which is part of the complete package of a great engine, but with 6 pieces EGTB those engines that are superior with more knowledge will only draw against those that do NOT have great endgame knowledge. Remember what is the real purpose of testing Eng Vs Eng, it is NOT to see if 6 pieces EGTB can force a weaker engine to get a draw when it is pitted against a stronger engine, instead testers should only be testing to find out the real strength of engines, not to see if the EGTB can find a Draw or Win.

Stockfish was developed with endgame knowledge from the start.
Nowadays 80 Percent of the engines above 3300 can NOT select the correct and tempting move Bh3! which is to to see if the opponent engines blunder and take the Bait, in which Black has an easy Draw, but Stockfish 3 even an early version can pick up the best tempting move immediately and it does not fall for the trap and avoid to take the Bait.

Re: Black to play and Draw, which engine can solve this Puzzle ?
I’m not interested in easy puzzles.Chessqueen wrote: ↑Thu Jun 16, 2022 10:29 pm The point that I am trying to make is that any engine that is much much weaker than Stockfish or Komodo Dragon lets say an engine between 2400 to 3400 can draw against them using the 8-pieces endgame tablebase, and testing will NOT make any sense at all since the more knowledgeable engine like Dragon or Stockfish will be losing a lot of points against weaker engines, and at the same time all the extra knowledge become useless, since weaker engines will have lots and lots of draw if they reach position like this playing the Black side.
Note: Therefore, testing engine vs engine should be limited to only 5 to 6 pieces endgame tablebase

I’m always using a MacBook Pro 16-inch M1 MAX all-in version.
I’m always using newest Stockfish dev.
I’m always using 3, 4, 5, 6, and 7-piece syzygy endgame tablebases.
= Nearly all 8-piece endgames should be solved.
= People should start creating more difficult puzzles with 9 pieces or more.
= Stockfish developers should always test and train Stockfish with 3, 4, 5, 6, 7-pieces syzygy endgame tablebases.

Re: Mini-FRC Tournament Season 1
Why is he using the 6 Syzysy EGTB? If it is for testing engines it defeat the purpose of letting the engines to use their own endgame knowledge. I can justify only using 3-4-5 pieces EGTB, but NOT 6 Syzysy EGTB; since there are lots of engines rated over 3250 with poor endgame knowledge that can NOT even select Bh3! or the best response which for White is g3, since everything else draw for Black without using 6 Syzysy EGTB with this position.

Re: Black to play and Draw, which engine can solve this Puzzle ?
You did not read where it say without using EGTB
, It is not meant to test your EGTB, but the endgame knowledge of engines rated below 3500
