TOPIC: Large Repertoire Database vs Multiple Smaller Repertoire Databases

Re: Large Repertoire Database vs Multiple Smaller Repertoire Databases 3 years 1 month ago #106

Dave, I've been following the Grandmaster Repertoire series too and programming in as you suggest. I'm most of the way through Mihail Marin's texts on the English and Lubomir Ftacnik's on the Sicilian. Which have you worked through?

I only put in the main moves for the side involved - i.e. I only put in Mihails recommendations for white in each case, though I do include all the options for black so that I should be prepared for anything.

Would you be interested in pooling resources?

I keep one large Repertoire Database on CPT which is complete and configured with Opening/Defense/Variation(s). This is my master file.

Then if I am preparing for an event or wish to create a training book I import the CPT files into a new repertoire in which I can make some final decisions. The import functions within CPT make this a relatively painless approach.

Chess is one game.
Starting from two tabiyas
one with white, and one with black

I am one person i do believe
So I therfore have one reportoire
called my killer reportoire

Sometimes Im black
Sometimes Im White
Sometimes Im dirty
Sometimes Im freshly bathed

I use one reportoire database as white
And I use my other database when Im white
These two are the two parts of my killer reportoire

But I also have other databases that are not part of my repertoire
I thinking of calling them A00... E99
I know its a little bit uncreative but Im a child of the Informant generation!

Super Dave has created Tabiyas!
Oh holy ghost
using Grandmaster Repertoire books to empty his pockets
me myself thinking my destiny is to empty them on some new app
I feel crap whanna give myself a slapp for thinking Chess Reportoire can fix my Rep.

Super Dave 937
Wanna ask you what Fischer random pos 937 is?
No sorry just me beeing funny.
Im imprested you have imported from Grandmaster Reportoire
How do you do that in an easy way?
I guess you not entered them by hand
Its so nice seeing your results!

When you talk about ”Actual games”
I can see that a great way to use CPT is to import all your played games
I regulary play throu my games about 1.000 rated games (with Chessbas)
I know those games most of them but cant pinpoint all moves
But it would be great to use CPT for remembering my games
To download them to my biological CPU!
Reading your comment was great - hope I can take all in of those great things you say!

Large Repertoire Database vs Multiple Smaller Repertoire Databases 2 years 11 months ago #161

Hello, I've recently gotten back to the updated CPT. (I like it.)
I have transferred my Rep as Main database and labeled another as Occasional which I use for interesting or offbeat openings. I've used several sources throughout the years. GM Reps, Correspondence games. I also used Chess Opening Wizard (COW) and transferred my primary lines over to CPT. (I find it very easy to get to big and often prune lines I don't like or use by either deleting them or transferring them over to another DB.)
I like using SCID and Chessbase to find what is most popular. It is also good to dumb down the databases to find what is played at club level or narrow the search to reflect what you will most likely play against. I also keep an eye on the most popular Opening books on Amazon.:)
I find a wide, lower tree to be most helpful and flesh out the lines as needed referencing typical games and endgames.

Do you prefer to have one (maybe 2: 1 for White, 1 for Black) repertoire databases or do you find it more practical to multiple?

I have been doing the former: 1 big database for my Black repertoire where I have my Dutch against 1.d4 and 1.c4; my French against 1. e4, my responses to odd White first moves - generally Dutch in nature. It gets rather big...

That is why I am thinking of changing to several smaller databases. I think it may make for easier 'on the fly' changes to a given opening approach - plus, I do not wipe out whole reams of lines I have worked on.

One question Leavenfish. When you say "database", do you mean an actual separate database file or do you mean multiple repertoires in one CPT database?

I like the idea of using multiple smaller repertoires but keep them all in one database file. Then, when I want to train all the openings, I can create another repertoire called "Everything" and copy all of the smaller ones into the Everything repertoire (which is still in the same CPT database file).

Since I have only a couple of opening systems, and since I use folders, it doesn't take much time to copy them into one large repertoire. As I update my smaller repertoires/folders, I can periodically delete the Everything repertoire and re-copy the smaller ones. It takes less than 5 minutes and I have the best of both worlds.

This fits my style of creating my opening systems. I create my white openings from repertoire books. Each repertoire might have three or more books. So I name the repertoire item the opening I am creating. Then, under the White folder, I created sub-folders, one for each book. Then, under those folders, I create an opening for each chapter in the book (most chapters are dealing with a particular reply at key points in the line.

If the books overlap information, then I just skip that part of the second book.

And, of course, I don't import the book. I do it by hand, chapter by chapter. By the time I am done with a chapter, I've generally read it a few times through before all the moves are in CPT. So besides helping me train the lines, CPT helped me slow down and not speed read through the book. By the time I finished entering the book, the training of the repertoire goes much easier because I have a strong grasp of the principles of the opening.

For me, the Encyclopaedia of Chess Openings (ECO) was a good starting point.

I did not see any sense in trying to re-invent the wheel, but chose to borrow from much of the known chess wisdom already developed by many players over time. And CPT is an extremely helpful tool in learning this known content. So, I set out to methodically learn how each spoke in the wheel of chess openings works?

I created the following CPT Repertoires that reflect the ECO method:

FLANK OPENINGS
SEMI-OPEN GAMES
OPEN GAMES
CLOSED GAMES
SEMI-CLOSED GAMES
INDIAN DEFENSES
IRREGULAR OPENINGS

Then, within each CPT Repertoire I created (and hand-coded in) the relevant New Opening.

Unlike importing a database, this approach means I ‘forced’ myself to do the hard yards and learn the openings as I went. It is slow, and is day-after-day, and it takes some reading and thinking.

This learning has not happened overnight and for me it is a joy to use CPT to be deeply inside each opening, variation, Tabiya, etc. by coding them in as a New Opening, New Variation, Add Position as Tabiya, etc. with CPT.

Doing it this way, means I get to explore the strengths and weaknesses of the relevant opening and how their characteristics mesh into the Middle Game (where a lot more strategy is played). Isn't this why we learn openings?

Now, through CPT coding and then CPT drills, I instantly ‘feel’ an opening pattern coming on (through recognition) and I get excited as the associated name comes into focus when an exact pattern emerges. Importantly, I can now instantly predict many known variations, defences, gambits, weaknesses, etc.

If I see a pattern I don’t know, or I have forgotten one, I research it, explore it, learn it and then newly code it into CPT, or I re-learn what I forgot with CPT in focused drills as needed.

For example, within the repertoire FLANK OPENINGS, I mirrored the ECO listings:

White
English Opening
Zukertort Opening
- Reti Opening (variation)
Bird’s Opening
Larsen’s Opening

Black
Symmetrical Defense (to the English Opening)
Reversed Sicilian (1…e5)
