Do you have an opening with thousand of (complex) positions? Wouldn't it be great to know that your opening contains no blunders / missing critical candidate moves for your side or your opponent? CPT 4.2 will offer a new function to give you exactly this power and more.
Let's run through a simple example to demonstrate the new feature. Our repertoire contains the Scandinavian opening. Let's assume for some reasons we entered c6 instead of moving the queen to for example a5. And then we didn't take the queen, but continued in standard manner:
Now, we use the new function "Analyse Opening". A dialog-box offers many differents option before CPT starts with the analysis.
In a real-world scenario you probably don't want to let the engine analyse the first moves. You can decide whether the engine should analysis to a certain depth each position or for a specific time.
Furthermore you can let the engine update all analysed positions with its own evaluation or make it dependend on the last analysis date. You can also just focus on all end positions to use the "min-max-function" afterwards. Finally, you can let the engine mark critical positions. A critical positions means that you are missing an important candidate move. You can define how much better the candidate move has to be than the best already existing one in order to avoid too many updates for basically similiar evaluations.
We start the analysis:
The analysis of a complete opening can take some time. CPT gives you an overview of what it is right now analysing.
What does the result look like? Did CPT find the blunders?
Yes, indeed CPT found the blunder by Black. The position is marked as "Engine (critical)", which let you easily get back to the position later. At the same time it added a comment on its own showing the move, which is missing from the engine perspective and how the analysed variation goes. You can now decide to add Qa5 to your candidate move list.
What about our mistake of not just taking the queen?
The engine found this mistake too.
Now, these have been very obvious examples. Imagine a real opening with many positions and you will see how this new feature will give you a big advantage over your competitors.
