An experiment (tome II)

Post by Sylwy »

After this post, get rid of me for two months. Fortunately, the Eastern Carpathians support me without any problems. They have historical experience with various characters. :wink:
Some time ago I was intrigued by a post of oliprog-alias Massimiliano Goi-on Chess2u forum:

This post was applauded by a consistent number of other scientists (e.g : ZamChess-alias Jorj Bostanel; AlexChess-alias Alessandro Morales & so on).
In essence, I want to verify oliprog's statement in two steps:

1.-first step (today's): one engine plays with experience file and without books, the other engine plays only with books;
2.-2nd step (in October when I return from the mountains): the same engines only play with books, without using an experience file.

I WANT TO SEE WHAT DIFFERENCES EXIST!

So, the first step:
===================
Conditions of the match:
-StockfishMZ 230522 (the current champion on my PC) = a SF derivative with Sfnnv5 net architecture + Eman.exp_050522 file + no book
-Deep Blue_110622 = a SF clone with a Sfnnv5 net architecture + 2 books(Lobo+Mantis-DH) + no experience file
-TC=4'+2"
-Hash=256 MB
-GUI: Arena 3.5.1
-1 thread-CPU=Intel i5-7400-3GHz (Kaby Lake)
-TBS: 6-men Syzygy bases for both engines
-OS: Windows 10 Home.

The final result is:

+1 -0 =99

+7 Elo points for StockfishMZ 230522 bmi2 (my PC champion).

One note: the experience file is more than four times the size of both books.

The single victory: :lol:

Some time ago I was intrigued by a post of oliprog-alias Massimiliano Goi-on Chess2u forum:

This post was applauded by a consistent number of other scientists (e.g : ZamChess-alias Jorj Bostanel; AlexChess-alias Alessandro Morales & so on).
In essence, I want to verify oliprog's statement in two steps:

1.-first step (today's): one engine plays with experience file and without books, the other engine plays only with books;
2.-2nd step (in October when I return from the mountains): the same engines only play with books, without using an experience file.

I WANT TO SEE WHAT DIFFERENCES EXIST!

So, the first step:
===================
Conditions of the match:
-StockfishMZ 230522 (the current champion on my PC) = a SF derivative with Sfnnv5 net architecture + Eman.exp_050522 file + no book
-Deep Blue_110622 = a SF clone with a Sfnnv5 net architecture + 2 books(Lobo+Mantis-DH) + no experience file
-TC=4'+2"
-Hash=256 MB
-GUI: Arena 3.5.1
-1 thread-CPU=Intel i5-7400-3GHz (Kaby Lake)
-TBS: 6-men Syzygy bases for both engines
-OS: Windows 10 Home.

The final result is:

+1 -0 =99

+7 Elo points for StockfishMZ 230522 bmi2 (my PC champion).

One note: the experience file is more than four times the size of both books.

The single victory: :lol:

87...Nxb4 is a surprising blunder by stockfish and it seems that white has a forced win by 88.Kxb4 based on the 7 piece tablebases.

Also without tablebases it is clear that it is not good to take on b4:

Rebel 14.1 chooses 87...Nc7 instead of 87...Nxb4
