to choose openings to learn : expRate and openingRate
I check several opening's lists on my experience file and on experience files/opening books from other users.
Then I compare the experience rate of each opening and select the ones where my experience file has no experience data.
I also select tourney's openings where Eman will play.

to learn openings : cutechess-cli
I run a gauntlet with Eman against few opponents for each opening to learn.
Since i made my learning farms, Eman can learn several openings at the time.
At the end, i merge the experience files into one (then i defrag it and i fix it).

to find experience data to reinforce : expToPGN
I check all the learned openings in order to find experience data with shallow depth.
The tool creates one pgn per opening with all the moves/lines to reinforce.
Then I append all pgn files into one.

to reinforce experience data : commenter_pgn
Eman analyses at D40 each move of each line of the pgn file.
The tool saves the analysed positions in order to save time.
Eman also analyses at 10min/move its lost games.

Thank you very much for the explanations

Regards

Oh and will this experience file ever be made public or is it only trained for private purposes?

My eman.exp was already published until 2022 but i didn't like its misuse by idiots, cheaters, saboteurs, traitors...

In order not to punish other people, i published on github the tools to edit and improve their experience files.

To my knowledge, no one has equivalent learning data to exchange with me, so mine is private.

I'm a total amateur, but I already gave you Eman's experience on fourm MZ once, in the future I'll give you a second time

Thanks again for your help

What to do after learning an opening ?

Previously, Eman learned the "b90 f8e7" opening thanks to a gauntlet of 4 x 500 games (Eman vs BrainLearn/HypnoS/ShashChess/Aurora) :

[Event "Eman's learning"]
[Site "deeds"]
[Date "?"]
[Round "?"]
[White "eman"]
[Black "eman"]
[Result "*"]
[ECO "B90"]
[PlyCount "20"]

1. e4 c5 2. Nf3 d6 3. d4 cxd4 4. Nxd4 Nf6 5. Nc3 a6 6. Be3 e5 7. Nb3 Be6 8.
f3 Nbd7 9. g4 h6 10. Qd2 Be7 *

So after learning 2000 games on an opening, here is my routine...

1°) how was the learning of this opening ?

For that I use pgnToScores to get the general learning curve, to see the effectiveness according to the opponent, to get the ELO scores, etc.

pgnToScores.exe "b90 f8e7 - eman_experience_vs_brainlearn_hypnos_shashchess_aurora.pgn"


"learning session 09.ods"

reminder :
from the 1st to the 500th game : Eman starts without experience data (on this opening) and plays 500 games against BrainLearn
from the 501th to the 1000th game : Eman starts with experience data from 500 games (on this opening) and plays 500 games against HypnoS
from the 1001th to the 1500th game : Eman starts with experience data from 1000 games (on this opening) and plays 500 games against ShashChess
from the 1501th to the 2000th game : Eman starts with experience data from 1500 games (on this opening) and plays 500 games against Aurora

"learning session 09.ods"

reminder :
Aurora (=the Eman's opponent from the 1501th to the 2000th game) is Stockfish + learning feature
Here, all engines have a learning feature so they don't play several times the same bad moves

2°) what are the most effective moves ?

For that I use "scid vs. pc" to see the most effective moves, to update my opening book, etc.

"scid vs. pc"


On the "key" positions, i check what moves are configured in the other opening books :


I update my opening book with the other most used moves :

3°) what do the experience files contain ?

For that I use "(brainlearn) experience viewer" to see the experience data of each engine.

Eman


BrainLearn


HypnoS


ShashChess


Aurora


The "count" and "depth" values of the "h2h4" move (11. h4) confirm that this move was the most played.
The "score" and "quality" values of the "e1c1" move (11. 0-0-0) do not always show that it was the most effective.
When the engines will read their experience file, they won't always choose "e1c1".
Without user intervention (experience data reinforcement/editing), the "experience book" or the "self-q-learning" features will often be mistaken and choose "h2h4".
Hence the interest of using an opening book containing the most effective moves obtained at learning.

4°) What is the ELO rating (on this opening) ?

For that I use ordo.

(optional) Which move Eman played against which opponent ?

For that I use pgnToMovesFreq to see how Eman switched between the moves on "key" positions.

pgnToMovesFreq.exe "b90 f8e7 - eman_experience_vs_brainlearn_hypnos_shashchess_aurora.pgn"


"exemple.ods"


"exemple.ods"


Even in a "key" position poor in move choice, all engines tried other moves.
Against BrainLearn, Eman started to learn the "e1c1" lines.
Against HypnoS, Eman quickly switched to "h2h4" in order to learn new lines.
Against shashChess and Aurora, Eman was able to improve all its lines (evidence ? see the general learning curve, the elo rating...)

The distribution of trained openings is rebalanced after each learning session :


The experience files must still learn tens of openings already present in the opening books (ex : Solista, Mantis, Hubble) :


The experience files must still learn few openings already present in the other experience files (ex : ProteusSF, Cumnor) :
