CPT 4: New Repertoire Explorer

When I announced the development of CPT 4 I already talked a little bit about the new repertoire management in CPT 4. This time I will explain the new concept in more depth.

Repertoire Explorer in CPT 4 

The following repertoire elements exist in CPT 4:

  • Repertoire
  • Folder
  • Opening
  • Variation

Where “opening” is basically what is called “sub-repertoire” in CPT 3.x. CPT 4 will offer specific concepts to manage repertoires for tactical positions, chess puzzles, end games etc. Thus it makes sense to get rid-off of the rather abstract term “sub-repertoire” in the context of opening repertoires.

For each repertoire there are automatically created two folders called “black” and “white”. You can’t delete them.

The new repertoire elements serve you to organize your complete repertoire in a more convenient way. In CPT 3.x every sub-repertoire is managed on the same level and basically no other repertoire element exists. You can’t create any hierarchy. Furthermore there is no way to manage more than one repertoire at the same time. You have to load each repertoire and by doing so you are closing the other one.

Now you can create as many repertoires in the same database as you like. No limitations anymore. Everything right there at your finger tips. As the new folders “black” and “white” are introduced where is no need to create a specific repertoire for each side. Furthermore you can manage in the same database a repertoire for your blitz games and your standard games or one for attacking / risky play. Again, no restrictions here.

 

Another issue about the way CPT 3.x manages your repertoire are transpositions. They are only covered within one sub-repertoire, but not across several sub-repertoires. Unfortunately there exist many openings which let you transpose between each other …

In CPT 4 you can navigate through your KID opening and when it transposes to your French opening CPT will show you the information right away. You change the evaluation for a position which exists in two openings (e.g. the start position) and it will be show in all other openings to which the position belongs as well. The same is true for comments. You delete a position in one opening and it will be permanently deleted only if it is not part of any other opening. Otherwise it will be just removed from the current opening, but won’t impact any other opening.

Some players complained that they play an opening with both sides, but there was no simple way to manage and train the same opening for both sides.

In CPT 4 you can easily drag & drop an opening from let’s say a white folder to a black folder and there you are. CPT is not going to create double entries for each position. Remember, CPT 4 considers transpositions across sub-repertoires. It always stores a position only once in the database. Now, you will be able to easily add new moves to let’s say the Dragon opening from white’s side. However, those moves are not automatically added to the black opening for the Dragon. You will see them grayed-out in the candidate move list so you can easily add them to the other opening, but by default CPT assumes you want them just for the opening which you edit right now. While you share positions among all openings you are still able to add and remove individual candidate moves to your liking and even the order of the candidate moves can be different for each opening even though the position and candidate moves themselves might be the same. Sounds a little bit abstract? Well, in short: CPT will act as you would expect it in the background while giving you a maximum of flexibility.

Now, let’s have a deeper look at the repertoire elements.

 

Repertoire

You can add at any time a repertoire to your database. Then CPT will automatically create a folder for your black and one for your white openings which you want to manage under the newly created repertoire. Thus a repertoire by itself is not assigned to any color. The training score of a repertoire is based on all openings which are assigned to your black and white folders.

Folder

That’s a new construct. It will help you to organize more complex openings like the Sicilian. By itself is has no function. It can contain as many sub-repertoires or folders as you like.

Opening

Formerly known as “sub-repertoire”. That’s the core repertoire element. Openings let you divide your repertoire into logical units. Any opening is either for black or white. You don’t have to explicitly mark an opening as black or white as the parent folder holds this information.

Openings are also what you can train in the training centre. CPT 4 let you train across several openings.

An opening has a training score which is the average training score of all positions which the opening contains.

Variation

Well, these repertoire elements are more or less just “labels” in terms of CPT 3.x. However, they are integrated into the repertoire explorer and the repertoire hierarchy which makes it much easier to utilize them. A variation doesn’t have any training score. Think about a bookmark to get the idea of variations. If you want to create a variation you have to open an opening. Then navigate through your opening to a key position or variation. Now, mark this position as variation and give it a name. It will be shown below the opening in the repertoire explorer. If you want to get back to this position later again just double click on it in the tree. You can have an unlimited numbers of variations for an opening.

 

Well, that’s a rough picture of the new repertoire concept.

Thanks for revealing this detail for CPT4 . It looks very good. Very well done (great new features).

The key burning question remains still ie when is CPT4 ready for release?

Till then, good luck with finishing the work to CPT4 & looking forward still to it's release, regards,

Thanks for a brilliant program!

What I find most confusing is how to get the Training part of the program to test for all variations of best moves in a sub- repertoire.

With thanks

When released, I am certain CPT 4 will be a truly amazing program. It's putting on muscle, so to speak, and the new features will definitely be something to look forward to.

When I first downloaded CPT a little less than two years ago and gave it a test run, I was truly impressed. My only quibble was that it did not have any print functions. Normally a player would want to bring his repertoire along to study anywhere he goes. But with CPT, unless one has a notebook computer, the repertoire remains at home on the pc.

So, our dear friend Stefan, will CPT 4 now be able to print out repertoire sheets? I believe that being able to print repertoire sheets is a MUST for CPT.

Again, thanks for a wonderful program and God bless! Warmest greetings from the Philippines!

I still can't believe something like CPT ( that I had been looking for for so long) is available and free. Thanks again!

Will you be able to just load version 4 on top of 3? And how will you get current repetoires moved over if not?

Dear Stefan, your job is really great!

Reading the new features and looking the new screenshots, CPT 4.0 looks wonderful.

Many thanks, Stefan!
