The 5men and 6men Syzygys challenge for the top 3 Engines.

Post by Chessqueen »

I noticed that most of the testing are done with either 5men and 6men Syzygys, but have you noticed any game where the top engines has lost a single game if it does NOT use 6men Syzygys ? The challenge is if you can provide the fen where either Komodo Dragon or Stockfish 13 NNE can NOT find the correct sequence of moves without using 6men Syzygys ?

Okay so Nobody came with a 6 piece men Checkmate. I will post this fen Black to move, but White has a brilliant way of winning, believe me with the best sequence of moves White can still win this endgame, only use whatever top engine you want to use, but without using 6 men EGTB or 6men Syzygy, and it should be Mate in 17 moves white the White pieces.

As far as I know, the Stockfish app on the App Store doesn't have a tablebase yet it finds the mate in 3 seconds.

That is exactly the point that I am trying to point out, now if you use the 6men Syzygys EGTB it will NOT make much of a difference, and most of the top 3 programs can find the correct sequence of moves without having to use 6 men piece EGTB, the breaking point would be probably engines rated below 3300 which could benefit tremendously by using 6 men EGTB. Here is Black diamonds and I am pretty sure that Crystal, Honey, and Komodo Dragon can also find any mate for White with 6 men pieces involved.

It would also be good to find out if Defenchess 2.2 rated 3354 or Shredder 13 rated 3322can solve it without using 6 mem EGTB, in order to know what is the minimum rating of engines that can find the correct sequence of moves, and if they can NOT find it those would be the engines that really kneed 6 men EGTB.

I don't know how the tablebases work but probably 5-men tablebase already had the knowledge so 6-men tablebase doesn't require in order to find the fastest checkmate. There must be niche problems for them I think, other than that you are right.

That is great to know that Stash and Cheng can find mate without using 6 men EGTB, therefore, 6 men EGTB is NOT really needed for engines above 3200, but it took Cheng 4.40 much longer to find Mate then it did with Stash v30.0 :roll:

I do NOT have your excellent Stash v30.0 to test this but with an extra White Bishop, I wonder how Stash and Cheng 4.40 do with this position, White to play and Win with NO 7 men EGTB or 7men Syzygys :roll:
