How to Make a Custom Chessable Opening Course Based on Win%

I have long wanted a simple way to play the opening without learning GM-lines, so I created an easy method to make a simple opening repertoire. In this blog post I will explain how you can do the same.

Pick an opening (Sicilian, French, Caro-Kann, etc.)

In this blog post, I will use the example of a rep. for Black against anti-Sicilian openings. First, set the opening book in a Lichess Study to be based on Lichess-games and on the rating group you play against. This way you will be making your rep. based on what you most likely will face.


Next, create a study and map out the main variations that later will become chapters in your Chessable course. The next step is to create a chapter in your Lichess Study for each main move.


Now it is time to select the moves for your rep. I have done this by picking the move that has the highest win% in the Lichess-database within 0.2 of SF evaluation. Thereby I will both play a move that has a high chance of posing my opponent problems and is also approved healthy by the engine.


Now for the first move of the rep. against 2. Nc3. The highest win% of the moves that are within the best move of the engine is 2..a6 with 47% Black wins. Then we pick 2...a6 and look at the most played responses by White: 3. g3, 3. f4, 3. a4, and 3. Nf3. Pick only the most likely replies, since if you go too wide your rep. will get very big!

You now repeat the process until you reach move 10 (or the depth you want to go after). In the end, you should have a nice tree of lines to import to Chessable. If you at move 10 arrive at a position with a tactical motif I would include it in the line, so you will practice it on Chessable.

Along the way, you will have to pick how many sidelines you want to cover, and when the Lichess-database gets too small. It maybe makes sense to only look at the engine evaluation after the no. of games falls below 100.

When you have mapped out the lines you have the option to annotate and draw lines to help you understand the positions. If you don’t understand a move/position go back a step and pick the second-best option.

Go to Chessable

Now that the rep. is ready it’s time to create the course on Chessable. When you create the course go to the course control panel and create the chapters that match your Lichess study. This is an important step to remember. You then go to the owner’s option and import the chapters-pgn to the matching Chessable-chapter.


When you are done it will look something like this:


Final thoughts

I think that by doing your own course you are actively learning while you create it and you can investigate the moves in the process, secondly, you get a rep. that is manageable and fits your own needs, and finally it will be based on the moves you will most likely see in your games according to your rating. You can also make your own selection algorithm or base it on a course/book of course..

Let me know if you try it out!
