Opening Preparation

Build, Customize, and Train Your Opening Repertoire

The Opening Preparation page in Chesspertise allows you to create and train your own opening repertoire in a simple and practical way.

No complex setup. No manual copying of lines.
Just real openings, trimmed to exactly what you want to learn.

Create Your Opening Repertoire

Creating an opening repertoire is easy.

On almost any page that includes a chessboard, you will find two buttons below the board:

• + White Repertoire

• + Black Repertoire

When you click one of these buttons, Chesspertise asks:

• Which repertoire you want to add the line to

• Or whether you want to create a new repertoire

Once selected, the opening line is added instantly.

Learn from Great Players — and Trim What You Don’t Need

You can base your repertoire on the openings of real chess players.

For example, if you choose Garry Kasparov, you will see that he played:

• 1.d4

• 1.c4

• 1.e4

You may not want to study all of them.

Chesspertise allows you to trim the opening tree, removing the lines you are not interested in, until only the variations you want to train remain.

Why This Matters

An effective opening repertoire should be as narrow as possible:

• Less memorization

• Deeper understanding

• More focused training

You train only what you actually plan to play.

Start Opening Training

Once your repertoire is ready, you can begin training immediately.

1. Click on Opening Training

2. Select:

   • The color (White or Black)

   • The opening repertoire (e.g. Kasparov – White)

3. Click Start Training

You are taken to a dedicated training page.

Interactive Training with Visual Feedback

During training:

• You play your side of the opening

• Chesspertise plays the opponent’s moves

If you need help, you can click Show Tree:

• The line you are currently training is highlighted in blue

• You always know what variation you are working on

Learn from Mistakes Automatically

Whenever you make a mistake:

• The error is saved directly in the opening tree

• Over time, it becomes clear:

  • Which lines you know well

  • Which lines need more work

You can:

• Restart the current branch

• Take back moves and try again

This creates a feedback loop that focuses your training where it matters most.

Train Smarter Openings

With Chesspertise Opening Preparation:

• You see immediately which lines are strong and which are weak
