Question for Laskersnephew and others: My copy of CPT lost it's Stockfish engine. When I try to reload it, I get the message: "The registration of the chess engine failed. Please make sure you selected a UCI engine." Well, Stockfish is a UCI engine. What should I try to get the engine back working?
Comment/Question: Many are suggesting Chessable. Chessable has 100's of books on it, but is there a feature to practice against my specific repertoire? I don't know about this.

What do you mean lost it's engine? After every Stockfish update I download the newest version and tell CPT to start using that one. That process takes just a few minutes. And now I can switch between multiple Stockfish versions whenever I want to (takes 2 seconds).
I use Chesstempo nowadays.

I just started to use the scheduled training options of Chess Position Trainer. Anyone has any experience with this? How dose it compares with Chessable?
CPT looks like the tool one really wants to build and train your own repertoires.
However it's not being developed, is rather large software, etc....
Chessable is modern, actively developed, and can be used on any browser/mobile.
However.... organising content is not as easy, because it doesn't remember POSITIONS, it stores lines. Then if for example you have a branch, where the opponent can do 4 things, and then next move another 4 each, instead of a limited number of positions, you'd create 16 lines.
The spaced repetition is fine, and you can write comments, annotate moves etc.. and then train on mobile whilst waiting for the bus....
However, some things are a pain, if you want to explore the "tree", you have to use opening explorer, you can't see all the branches like CPT, and it does tell you that the position exists in your courses, but not how many, and where, so you click "find in courses", which goes to a new page, and if you want to return to your position, you have to start all over again.... so some things are very frustrating. But, if you set up your repertoire in a well organised and systematic fashion (learn how it all works first and try it to understand what setup will work best before you put everything in there!), then it's really fine.
As I said, reason I chose it was a) spaced training of your own lines b) in development c) can use on any device from anywhere
You'll probably need a paid up account though to access all the features and make your own courses, I think you can create 2 for free or something.
Hi! Those software tools are nice of course, but what about customized chess coaching from an expert player. This can save you a lot of time to get on track for progress. Please check my profile and should you be interested in lessons, just let me know by sending me a message.
Good luck!

Thanks for your response, Duckfest. I can get CPT to use an older version of Stockfish ( think it's 6), but when I try to get it use 15, I get the message posted above. Any thoughts?
Just in case you are interested in such a program. Chessable is by far the best. It was already better than CPT when it was released. In Chessable you have support, constant updates, a community to talk about the positions, courses, etc. And you have courses which you can purchase or get for free. I used CPT for a while, but changed immediately to Chessable as soon as I tried it.
@NaturalMoves - Maybe your downloaded stockfish is not compatible with your machine. If your machine is 32-bit then you should stay with an older version. If your machine is 64-bit then you might want to try the POPCNT version.
You can test your downloaded Stockfish 15:
I'm betting you won't get to step 4. Pay attention to any output in the command prompt window for a clue what might be wrong. Once your test of stockfish is okay then you can try to use it in CPT or other GUI.
I learned a lot of openings with CPT 10 years ago. Improved my ELO by at least 100. I find chesstempo to have enough of the same features.
Can one still purchase CPT? My online payment gets kicked out, and not processed. Cant register on-site. Not sure what is going on.
EDIT: I just managed to pay them through Paypal. Still, no license key received. Does anyone know what to do?
I use the opening book editor & trainer at chess tempo and create my opening trees using lichess' AMATEUR (what people MY RATING are ACTUALLY playing, and/or failing in) database to build theory. you can also follow opening book videos on youtube to create your opening books there.
one thing, if you're going to make a book with a lot of transpositions, I suggest creating your trees one ply at a time starting with your main lines so all of your transpositions refer upwards. transposition theory only show up in the spot where you first play them. all future transpositions just end in arrows pointing to the continuation.
copying the moves where you are in your tree & pasting them into lichess' opening explorer lets you see what happens over the board in a position and what stalefish thinks of it. very often, moves fish states are as much as +5 can have terrible losing records in the real world
the tools you need are already online. I like too that lichess lets you download your trees so you can create duplicates for either merging theory, or pruning for more efficient study.
this is what your opening book would look like:
I remember begging anyone that would listen for more or less this tool as far back as the 90s! trees are the ONLY correct way to create an opening book and i'll argue with the entire planet until my last breath that variations within variations within variations is an abomination! it creates a wall of inscrutable noise that's one is constantly lost in whereas trees are trees! they're nicely organized road maps that are intuitive to navigate until you get to those darn transposition teleporters that take you who knows where.

Try to contact Stefan Renzewitz on support@chesspositiontrainer.comNormally if it is about license keys he will respond.
If you have entered the license key successfully, make sure to deactivate cpt before reinstalling ore upgrading Windows on your PC

Chessable is maybe better to train your repertoires but CPT is still better to create your own repertoires. Chessable has no option to jump to positions with more than one candidate move for your side (>1 candidate moves) for example. It is about time some good programmers make better tools for opening preparation. What I would like is CPT 6: faster, with a modern interface, without bugs and some added functionality. I also like the website https://chessmadra.com/ to fill holes in an existing repertoires.
@Ladyhawke79: Thank you for the reply. However I have tried support, and Stefans mail. Nothing yet.
EDIT: I just came right thank you. The payment went through when I replied to the invoice link in the email. Maybe he gives it an order number first.
Thank again.
Second EDIT: So the software is only valid for one year?? what?? Nowhere does it say this on the website. I just added the license key, so the Software added my name, unlocked all, and put a "valid till: 29 April '24" in? WTF.
I just started to use the scheduled training options of Chess Position Trainer. Anyone has any experience with this? How dose it compares with Chessable?
I never used this option in CPT. I just created small repertoires and trained them till I got a training score of 100%. Then I did reset the training scores and start over again.
I still do it this way but I also import the small repertoires in a big repertoire database as sub-repertoires. I train the repertoires in the big repertoire, where I never reset the training scores and use the scheduled training. I'm planning to ad endgame and tactics sub-repertoires to the big repertoire also, and use the scheduled training for this to.
