I recall someone saying that CA7 can find weaknesses in a player's repertoire
by showing what openings that he is uncomfortable with (losses incurred). Does
ChessBase 8.0 - 9.0 do this? I am interested in an upgrade but is willing to
wait next year to purchase. If you can contribute to this article please do so.
cordially yours, Larry

In CA7 for example, you can make a database with all the player's
games as white, then make a tree for it, which you can then play
through, and at each point it shows the statistical results. It is
actually probably the most used feature (the chess tree) and is very
handy for opening study. There is also a direct tree for the 2 million
plus game database and you can make other databases (such as all GM
games) and make trees for them also. Not sure if CB8 can do this or
not.


Yes, including the statistics.

Not sure about CB9, as it isn't on the market yet, but in CB8 the opening
report shows those weaknesses - and their strong points as well.....

All the best,

How do you make a tree in CB8? (or whatever its called in CB8). I haven't
figured that out yet. In CA7 there is a tree button to push

From the CB8 help file:


quote

There are two types of trees:

Book databases: Here you collect games in a database which is stored
permanently on your hard disk.

“On-the-fly” trees: It is possible to generate a tree very quickly from
any selection of games, e.g. all the white games of a particular player.
Right-click the games and select Game to Book (or press Shift-Enter).

How to create a new openings book
Database window: File – New – Database. In the file selector select the
database type Books (*.CTG).

How to copy games into an openings book
Select games, press Ctrl-C to copy, click the database symbol of the
tree and press Ctrl-V to paste. You can also Drag & Drop games or an
entire database into the tree.

I think that the readers of this thread should be aware that CB can create a 2
million game tree, but it requires days of processing and gobs of memory.

CA will do this in the space of hours, with a reasonably fast machine (say2+Ghz
P4), and reasonable amount of RAM (say 512M).

CA does not have the same type of opening report that CB has, but it does
analyze the repertoire of a player, and present a color coded explorer view of
the player's repertoire.

the hugebase tree was mentioned. And, in the context of opening analysis, it
is a very useful tool.

Extremely useful.

Also, thanks CeeBee for showing how to make the CB8 tree (you just make a
database of type book or something like that and it works fine)

One thing the CB8 book database has that is very clever is the average rating
of the players who played a certain move, and the performance rating of that
move. That is very useful (maybe other interfaces can add that at some future
point?) Maybe Bookup has that also, I don't have the Bookup Pro but I remember
we talked about something like that a few years ago.
