I made this cool opening trainer app. Felt like sharing it

You have to sign in before seeing anything. I'll be signing into what the unknown?
amazing! i just have no clue how to use it lol. could someone help?
Let's say you want to learn your shiny new opening: the London system.

1. Go to "Record moves" and put 1.d4 on the board. Because that's your first move
2. Now what critical moves could your opponent play against this ? First things first, let's prepare against 1...d4. Put that on the board
3. Your response against 1.d4 d5 might be Bf4 (or anything else really, it's your repertoire, you decide). Put that on the board
4. Let's now look at another response against 1.d4. Go back one move (use keyboard arrow key, or click on a move in the "game moves" list
5. We're back in a position where 1.d4 has been played. What about playing 1...Nf6
6. Put your response against 1...Nf6. Let's say it's also Bf4

At this point you have a repertoire that says you should play 1.d4 d5 2.Bf4, or 1.d4 Nf6 2.Bf4. Of course that's not much but good enough for an example.

Now navigate to "train" and play a move. If you play 1.d4 the trainer will respond with either d4 or Nf6, because these are the moves from your preparation.

Let's say you already forgot what to do next and play a wrong move. The trainer will ask you to try again, and you can now go to "Review mistakes" to see this exact position that the app knows you failed to play correctly (again, correctly = "according to your own repertoire". For engine analysis go to lichess, they do a good job).

"Review mistakes" will now show you this position from time to time, in order to make sure you don't forget it

And even nicer: you can now go to "lichess report" where your lichess games will be analyzed against your repertoire. If the bot finds a game where you played 1.d4 d5 2.Nf3 (which is not your repertoire), then it will show you that you forgot your own move. This also feeds the "Review mistakes" section

And you probably will see a game where 1.d4 e6 happened on lichess. That's not covered by your repertoire ! The lichess report will warn you against it (with a "Unknown variation" tag) so that you know there's a hole in your repertoire you should probably fix.

Rince, repeat, get better at chess B-)
Hi
I am on my way and it seems to work.
could add delete and train.
On mobile device the board is really small though.

No, sign up.
Don’t use your Lichess credentials unless on Lichess webpage.

Sorry you don't get peoples email address without a home page that shows and explains why. And then you make a TOS so that people know what they are getting into. We do not know you or your true intentions besides what you wrote in this subject.

If you want to test a website out don't start with no welcome home page and ask for an email.
People should not sign in like a blank check.
How hard can that be too.
