Welcome to try an application I made to improve your opening repertoire

Hi!
I have made am application that aims to improve you opening repertoire.

It will take your latest 100 games at chess.com and compare the moves you make with moves that are commonly played by top level players at the same position.
You get some statistics and images of positions with arrows showing the suggested improvements.
It takes 60 seconds, costs absolutely nothing, and gives feedback on games you have already played online. You can try it at www.aichesscoach.net
Let me know what you guys think of this. It´s been a hobby project for some time.
All recommended moves have been commonly played in winning games by top level players.
AiChessCoach.net is free to use. If you like it, please recommend it to someone!

Have a great day & best regards

Mats

Wow that is pretty awesome! I was thinking about something like that. Just tried it now

Thanks. Happy to hear that.

Thanks. You are welcome!

Is it safe to use, it says to download a pdf I would have felt safer If you had the results loaded online...

when in doubt, throw it out

that's what you do with food, but i think the saying applies here as well

@MegaPro-123 it does have the lock sign which "means it's secure" with your info... but you gotta be suspicious with less known applications and services. 

I LOVE that idea!!! Thank you!!!

It has 16 pages of information. Includes overview of openings, white/black repertoire stats, most common openings, worst openings, best openings, as well as move suggestions for positions.

I just don't like the idea of having to download pdf, maybe you could upload it online like aimchess? Just an idea, plus what Languages did you use @Gitarrtomten for the project? 

Hi there!

As of today, more than 1350 players have used the application. Apart from a few initial bugs or constructive feedback I have only seen positive feedback. I mean, it takes 60 seconds, costs absolutely and gives high quality feedback on games you have already played. 
If you don’t want to download the pdf you can configure your browser to view the pdf instead.

Play chess and have fun!!!

Interview with me about AiChessCoach.net by swedish chess association published on schack .se. Google translated from swedish.
AiChessCoach.net helps you improve your chess openings based on your online games.

Interview:
Hand on heart. Chess is so immensely rich in possibilities that you can easily disappear into a rabbit hole.

Chess openings are one such topic: What should I play as white? And as black? What suits my playing style best? And how well do the openings really work for me?

The developer Mats Bäckström hopes to be able to straighten out all these question marks with his specially written program for chess openings: Ai ChessCoach.

His analysis program is free, and easy to work with. You upload 100 of your games you played on one of the chess servers Chess .com and Lichess .org and then you get back a downloadable PDF that analyzes your opening game.

- After 3 months of training with the app, I had raised my rating by about 300 points. Then I decided that it was good enough for others to be able to get better with it, says Mats Bäckström.

- One thing I really like about the app is that it gives tips on exactly the openings that are actually played against you, rather than focusing on openings that you hope will be played against you. So far, only one move forward is proposed, but I hope to soon be able to supplement with mainlines for the positions where you are most in need of them.

Now Mats Bäckström is interested in collaborating with Swedish chess talents who want to move up. Can his AI ChessCoach program help lift them to higher levels?

- It would be extremely interesting to be involved in helping promising chess players forward in their careers.

Have you had any helpers along the way with the program or have you done everything yourself?
- I have not worked with anyone but learned by searching online. I have reused code snippets I found online but I have done everything myself otherwise. Then I had some feedback on the early parts with Ari Ziegler, Anders Kvarby and once with Jesper Hall.

Have you been in contact with chess .com and lichess .org?
- I have not had contact with lichess or chess .com other than support when chess .com had trouble getting batch downloads to work.

Have many of your games on the chess servers been reviewed in your program?
- There should be 100 games if you have not played unsupported variants such as 3-check, 960 and the like. I tried with 200 games for a while, but since browsers often get timeout before the result is finished, users did not get their report. I may have to go over to email the report if it should work to have a larger number.

Do you have a business plan for this?
- I have no business plan yet. Or in part, if there is a large demand, it can be a premium service that, among other things, goes through significantly more games and has a little more features. I also do not exclude advertising on the site to finance the server.

How far do you think you have left with the project?
- With a family and a full-time job, it is difficult to say when new things will be ready. I also went to a training in computer science this spring which required some commitment so I had to postpone the launch for a few months. It is still a hobby project. But it is fantastic fun.

What's closest to the pipe - what features are you working on to further improve your program?
- I have started to combine deep analyzes from several chess engines at the same time to build up or improve different opening repertoires. There I have also managed to get the program to automatically classify whether a move is brilliant or not. A brilliant move then means that a move becomes the best move only at a very high search depth. It has been very fun to be able to confirm this on some classic moves.
- There will be main variants in the report with a focus on the positions where there is the greatest need for it. Here I am thinking about having the opportunity to have an extra function on the site called "Get Mainlines"where you enter the moves up to the position you want to study, choose which side you want to play, and you get a pgn file with main variants for the position based on 20-30 million games. Then you can study these in any chess program of your choice. In fact, it already looks quite ok. It is the web interface parts that are missing.
- If it becomes a premium service, it will probably add some game examples for the positions you have had problems with. It can be interesting for players at all levels. You can have a database with especially educational games for lower ranked players if you want.
The next step is to be able to enter 1-1000 or more games for your next opponent and get a ranking list on which the strongest moves are that have never been played against that player yet. Limited to the batches you enter but can be useful anyway. If you connect a few main variants to it, you can prepare very quickly against a new opponent if you have a few games to go on.
- Here I would like to try to work a bit with some up-and-coming talent with ambitions to beat the very best players.
- Then you do about the same thing again but instead of just picking out unexpected strong moves, you add to optimize subsequent moves to be as uncomfortable for that particular opponent as possible. Incredibly tickling idea, if you ask me.
- One thing that I have thought about is also the possibility that a chess teacher can get a compiled report with the most common mistakes made by a group of students. You could also add the ability to click a button to train according to openings selected by a specific instructor, if any instructor wants it.

Did anyone try to configure the browser to show the report in the browser instead of downloading it? Has it solved the problem to avoid download?

Wow -- this is amazing!  Thanks!

(I don't understand the repertoire suggestions, they don't resemble any games that I've played -- but that could be because I have a grand total of 8 games on here)

Just, really, fantastic.  Great idea.  Huge potentials (which you mentioned in the interview).  Five stars!!

@sholomsimon, Thank you!

It passed 1400 users today. Glad so many have tried it. 👍🏻

Question: I totally don't get the Repertoire suggestions.  So far, every game I've played has been Sicilian, with a limited repertoire, but your application had one suggestions for Repertoire Suggestions for Black E4:  and it showed me the following position:

and a suggestion that black play 3...Nf6

So -- what's behind that repertoire suggestion?  What's it telling me?

Thanks!

@sholomsimon, Nf6 will block a mate in 1.

White could otherwise play Qxf7#

Right, the mate threat is obvious.  But my question was: why did it suggest I learn that particular set up?  How often does one even get into that setup?

But then it occurred to me: my very first game as black here on chess.com started with that set up!   FWIW, I played 3...c6  - I don't think that was a bad move, was it?

But, still, the larger question (just curious, not criticizing) is: why, out of all my openings, did it pick that one to make a suggestion for me?
