1st of all,

I have managed to organize two kind of Duel competitions:

1st Duel Conditions: 2 Core/Game, 2m+1s, 128 MB Hash

All books are played by SF- PB 090223 (NNUE Enabled)

2nd Duel's Conditions: 6 Core/Game, 2m+1s, 512 MB Hash

Where all books played by CF-EXT 291120 (NON-NNUE)

And to be more clear,

RapTora's Experience played by Raptora 2.2 engine

Note also that Raptora 2.2 is played without any book

And in 1st Duel, Raptora is played as NNUE enabled

Sure in 2nd Duel, Raptora played as NNUE disabled

Plus in 2nd Duel, (to not effect the results),

A new fresh Raptora. exp is replaced/installed

And as we see (as NNUE enabled),

RapTora 2.2's Experience file is managed to win!

Where as NON-NNUE, Winner is Opening Book!

As a conclusion I can say, it seems

Exp. file performs better via NNUE assistance!

And meanwhile, according to Mr. Antonio Escobedo,

His RapTora 2.2 engine is trained to play vs books...

And after checking some of the games..it's clear that

RapTora's 1st moves are automatic, mainly up to 5-7 moves

But in some games, RapTora is going even deeper in lines..

That means it's trained, learned...and what I can say more, 

A very good idea, well-done and no BIG surprise that

The success is in the door! I hope also that other Engine

Learning Programmers will follow this excellent way!

But on other hand (in case of NON-NNUE...), 

Mostly Books performed better than Exğerince file!

Not sure exactly, but CF EXT 291120 can be another 

Reason about why...because based on my testings,

CF EXT is one of the strongest engines out there!

Or as other reason, Experience file suffers...sure

I am referring in case of running as NON-NNUE...

Some statistics about 1st Duel (as NNUE Enabled),

2 books (Ukraine 51, SF15f) performed better, nice!

5 of the books are performed worse than Raptora. exp

Where 21 of the played books points are equal...

Statistics about 2nd Duel (as NON-NNUE),

16 opening books performed better, not so bad..!

4 books performed worse than Raptora. expierence

Where 8 of the played books points are equal...

And without to not mention this I can't, reality is reality:

In both Duels: all books are played with disadvantage,

Because BIN book formats have no Learning Future!

I mean it will be more fair..if these kind of Duels matches, 

To be played, e.g as Experience vs CTG books...but

I've preferred BIN books under Cutechess GUI, due to

Fritz GUI has no concurrent option.otherwise too much

Complicated for my side, e.g running many GUIs.. .and

Via Cutechess, it's much easier running engine testings!

Plus I can save many CPU and free time, as you see,

The current tourneys are organized in very short time!

And I have to admit also that,

Running 1 Game per GUI: was popular 20-30 years ago!

But we are in 2023 right?..and I hope Chessbase will do it..

Otherwise, I am afraid to say that, (if concurrent matches)

I hope to use and run mainly Cutechess GUI or any

Other GUI, which has this great 'concurrent' option...

And here are Final Standings..sure you can

Appreciate whichever Duel ranking you like )

1st Duel (NNUE Enabled) the Winner is

Experience - Congrats to A. Escobedo!
