One persons approach:

I take a chosen defense…say the OKelly Variation of the Sicilian - 1.e4 c5, 2.Nf3 (and the alternatives) a6 from a good database or opening book, load all the main lines with branches thru about move 12. I then manually add all sorts of fairly early branches - many of which I am already familiar with because the OKelly is not very well explored in databases. I've played and researched it for years.

I then slowly tab thru each move of my database with a good engine running to display about 5 or 6 PV, adding ‘reasonable’ alternatives for my opponent not already in my new database/repertoire, but ALSO adding what might appear to be even better Black (my side) lines heretofore unexplored. In doing the latter, I can create my own 'theory' of improvements.

When that is done, I set CPT to run overnight analyzing deeper all the endpoints of the new branches I have created. This whole process helps me orient myself better and better in an opening like the OKelly. I then go back and try to identify with actual words what I as Black should try to do in these new end positions and may add a few concrete lines to CPT, noting pitfalls an unwary opponent could easily fall into. That is something I think people should look for - 'blunders' an engine spots which your opponent can fall into, and how to exploit them. It beats trying to spot them during actual game play!

In doing this, I have a GREAT feel for the defense...and have worked up a lot of good NEW ideas in the process. CPT is there to help me train them (or simply step thru the lines - as I often do - in POSITION mode)!

BTW, I have a GREAT record with the OKelly and would urge others to consider it. The really good players will NOT play 3 d4. Most below expert do which means instant equality in positions I know really well (thanks to CPT!). The best players often play 3 c4…and I steer them into lines of the Kan they would NEVER see if they met it straight away when their opponent opts for 2...e6.

I have created a main opening-database. It is about 20Gb now !!

All openings are in it. Except for 1.e4 some main-lines (already 50% i think). if somebody knows how to upload it decently let me k now and everybody gets it.

I'm afraid I don't have a clue.
But how did you create this?

I have entered all the main responses in the normal openings.
I am using my chessbase-database with 13 million games as a base to enter the most played moves.
Almost all entered moves are played 500 times or more.


the moves are entered manualy, as best as possible divided into the following openings :

a : 1...
b : 1.c4
c : 1.e4
d : 1.e4 c6 / 1.. d5
e : 1.e4 e6
f : 1.e4 e6 2.d4 d5 3.Nc3
g : 1.e4 e5
h : 1.e4 e5 2.Nf3 Nc6
i : 1.e4 e5 2.Nf3 Nc6 3.Bb5
j : 1.e4 c5
etc
.
.
z : 1.d4 Nf6 2.c4 e6

I am not importing PGN files (until now) to avoid the same lines occuring in different openings.


greetings,
Albert
