Mike, I lost my 7 year old Bookup program because my old computer died and I
moved and lost all my chess programs so I don't have any programs except
Shredder9 which I just bought. I suspect that Bookup's EPD format is a lot
faster than ChessBase's ctg format because to add a move on a 2.8GHZ
computer to a Chessbase opening tree takes about 10 minutes. Can you confirm
that Bookup can handle trees as large as the Fritz powerbooks and that it
won't take 10 minutes to add a new move. The next question is does Bookup
2005 have a large opening book as large as the Fritz powerbooks? And does
the Training Wizard in Bookup analyze positions?

With respect to studying *endgames*, yes, it's a good idea for me or
for anyone.
For openings, on the other hand, I tried getting a BookUp e-book. More
than one, even.
I'm still a patzer :-P

Ok. *Cite* some *former club players* who attribute at least a part of
their success in having *become* *masters* to their having used BookUp
*when they were patzers*.

Bingo! That's precisely what I've been arguing! There is *no point* in
patzers' using BookUp (or, indeed any other software or any books) to
study openings. It follows, therefore, that it is a *waste of money*
for patzers to *buy* BookUp (and, indeed, to buy books about openings,
unless perhaps it's something like "Opening Play" by GM Chris Ward,
which I own, have read, and even understand in part--being the
intelligent guy that he is, Ward is frequently *vague* in the *general*
advice which he imparts in OP ["Castle early-ish" is a typical example
of his vagueness]. This is presumably because *he understands* that we
patzers *don't understand* the concrete stuff which is what Kotov's
"Think Like A Grandmaster" discusses).

Indeed it won't, but then neither, paradoxically, will my studying
openings. Studying endgames and tactics might help.

Good point, John. You can download Bookup 2000 Express and it will works
forever for free. A great demonstration video (that I did pursposefully
with the program in it's "free" mode) is at...
http://www.bookup.com/chessvideo10.htm
For the first 30 days you also get instant editing features and use of the
Training Wizard that intelligently chooses which lines you need to study and
review if necessary. Register the program for $29 and you get that and
more, also forever.
The Professional version for $129 adds even more features and functions.
You can also add on more than $700 in ebooks.
So to answer your question, it is both free... and not. :)

Mike, does Bookup have an engine that will evaluate lines. Is that what the
Training Wizard does? if so what is the engine behind the training wizard? I
am getting disappointed with the ChessBase tree. I just bought Shredder 9
and it crashes whenever I try to add a new move or an evaluation to the
book.

You didn't answer my question. I acknowledged your belief that BookUp

There's the rub. *If* there is a point to it, then there may be a point
to our using BookUp. *If* on the other hand, we patzers *should not
waste time studying openings, but would be better advised to study
endgames* then Fritz works *better* than BookUp for that, IMHO. You
have brought to my attention an endorsement, on your website, from a
Canadian player named Michael Bennett, whose rating seems not to be a
million miles away from mine, and who uses BookUp for endgame training.
Clearly, BookUp worked for him, and that's great. For me, however,
Fritz/ChessBase is better because, as I have pointed out, it affords
the opportunity not only to do everything that BookUp will do for
endgame training, but also, crucially, to study the CD-ROM edition of
Dvoretsky's Endgame Manual, which is very fine, and has already won me
some rating points....

Bookup's backsolving "solves" all the analysis you put into it and then
backsolve. As you pointed out above, a single new discovery can overturn
years of master practice.

I'm still not sure what you are arguing.
I say it's good for patzers to study the analysis of stronger players and
that it does not inherently confuse anyone. Bookup just makes it easer for
patzers to study that analysis and test themselves on it.

Ah, the age old question. I have it that understanding chess is rooted in
the practice of separating Shinola from the lesser stuff. That's why I
learn so much when I use Bookup to pit the contrasting analysis of two or
more strong players.

I agree that if the general operation of your PC slows down then every
specific program slows down. This has nothing to do with the fact that
Bookup is not slowed by duplicate games and, again, can be expected to be
way faster than a game database when handling many duplicates.

Even now, if all game storage features were removed from Bookup, it would
still do many things that are not done by game databases.
Consider that back then - and now - the Encyclopedia of Chess Openings and
the Enclyclopedia of Chess Middlegames and the Encyclopedia of Chess Endings
contain no complete game scores. None. One wouldn't argue that a game
database like the Informant replaces the features of these Encyclopedias.
Neither does ChessBase replace the features of Bookup.
>> By combining the common positions it often saves disk space.

If 100,000 games start with 1.e4 in ChessBase database, that program stores
the move 100,000 times. A Bookup ebook stores that move and position only
once.
It's not a question of saving disk space. It's a question of what you're
trying to do with these different programs.

Wrong! It's also an *excellent* endgame trainer and at least a passable
openings trainer (although, to be honest,
I've hardly used that feature - for me, at least, the most effective
method for learning an opening is playing it online....
one quickly encounters all of the usual pitfalls in all but the most
unusual lines....).

Maybe so, but IMHO those intentions and purposes seem to overlap to

Fair point. I've read those only just now. GM Svidler is a world-class
player, to be sure (as well as being a most amiable individual). I can
understand why a super-GM, such as he is, might find BookUp useful.
Unlike me, he actually has a firm grasp of openings. Larry Stevens I
don't know, but that is undoubtedly more a reflection of my ignorance
than of anything else... I'm sure he's a good player.
It's interesting to me that Michael Bennett uses BookUp, as he says,
mostly for endgame training. This is precisely what Fritz does,
extremely well (which, evidently, you didn't know until I told you).
Indeed, with Fritz, there's the added benefit of being able to use the
CD-ROM version of Dvoretsky's Endgame Manual (which is in ChessBase
format).

Maybe it can do that research, but, as I've argued elsewhere, its being
able to do
such research may be of no use to a patzer such as I am, *because I
don't understand
what's going on in the opening*.

I take it that you mean: "Most of those club players who use it...".
Most club players I know
(those who own a PC or a Mac) if they have any chess software at all,
either have only CM9K or something similar, or they have ChessBase
and/or Fritz...
I remain to be convinced that BookUp enables them to learn openings so
effectively that they become
significantly better players more quickly than they would by other
means....

I'd suggest you get an ebook in Bookup format and begin understanding what's
going on in the opening. Using research by others has certainly already
helped you in the area of endgames, using your example of Dvoretsky's
research.

too. :)

The proof is in the pudding. The proof is not in this thread.
Even if 100 grandmasters credited their opening success to Bookup, I get the
feeling you would still excuse yourself as a patzer with an IQ of a hammer.
If you're looking for a list of C players who rocketed to grandmaster by
using certain software, I don't think any software maker will have the list
you're looking for. You will remain unconvinced, but remaining unconvinced
won't do much for your understanding of the opening.

Ciao Stefan,
Was ist los?
Are you inviting me to invoke the popular-but-ultimately-ineffective
dodge: "I've gotten a lot of emails..."?
I downloaded CPT a few months back, having discovered it in one of
these groups. I found it cumbersome and somewhat ugly. It seems to
suffer from the same sort of problem that appears to encumber BookUp...
Do you remember the ATARI Jaguar games console?
That was based on "the latest technology" - a state-of-the-art 64-bit
processor, no less. The games *looked awful* and the gameplay was
cumbersome at best, however....
For you, it may be a favourite program, which is fine, and you clearly
stated that because you "don't make really any money from it" you feel
that you have the right to post. It seems to me that *even if you did
make [big] money from it* you'd still enjoy "the right to post". This
is Usenet, for heaven's sake.
However, this thread is principally about BookUp, and, more
specifically, about its [evidently numerous] shortcomings (as I'm sure
you're aware). In the past, Mike has been accused, on numerous
occasions, of spamming. I remain "on the fence" as far as that question
is concerned.

Hmmm... yet according to the estimate which you make below, about 80%

published in London) that GM Julio Granda Zuniga of Peru, who works
much of the time as a farmer, does not study chess at all, but relies
solely on his (clearly considerable) raw talent.
It seems to me that most other GMs download TWIC every week, and use
ChessBase in their daily work... To me, this suggests that for 80% of
GMs, their doing these things is all of the "theory machine" they
appear to need. Would you agree with that assessment, even if, clearly

Indeed, what is the point of studying another player's analysis in, say, a
printed book? If there is a point to that, then there is a point in using
Bookup to vastly speed up the process.

I did not say they slow it down. In fact, I said that Bookup would be much
faster at handling it as the duplicate positions are never written to the
hard drive.
Again, you can call duplicates "bad" but they do not cause Bookup any
problems in database size or import speed, unlike a game database.

Again, Bookup was sold and used for many years without ANY game storage

Most people don't even use Bookup to store games. I'd recommend ChessBase
for all things game related, and you can quote me.

Fritz is hardly a competitor. It is priily a playing program with some
game database features.
It may sound wise to say that Fritz has shortcomings because it is not
ChessBase. And ChessBase has shortcomings because it can't do a dozen
things that Bookup can do. And Bookup has shortcomings because it's not
Fritz.
It's more accurate to say IMHO that these programs have different intentions
and purposes.

It's not a case of having an IQ around that of hammers, but few of us
actually do the specialized research the top players do with game databases
to prepare their openings, and only a few of those players have considered
that other software (Bookup?) can do that research.
Most club players are quite happy to get the Express version of Bookup and a
favorite ebook and learn an opening faster than any other way they know.

k,
just to add a new aspect:
www.chesspositiontrainer.com which is actually really 100% freeware (not a
trial version) has
a) probably the most sophistacted training center on the chess ket with
the latest beta 3.2
b) offers backsolving too
c) supports Crafty (and therefore crafty tablebases)
d) has a state-of-the-art interface
e) you will love the novelty feature if you play frequently on ICC or
playchess.com
Disadvantage for the a few more weeks/months: right now it is not good with
HUGE databases ( >100.000 positions), but if you really only want to manage
your repertoire I would certainly give it a try. I don't make really any
money from it so I feel the right to post.
Good news: Going to be available on Pocket PC and Linux, a new storagey
system is on its way - CPT is based on the latest technology. We are just
starting.

A new team member of CPT is only dedicated to work on this one. Basically
"only" a new Linux interface has to be developed (unfortunately not possible
to port from Windows). Most other parts of the code can be re-used without
changing a line of the code. I got the impression he is very skilled and
motivated. He showed me already first results of the new interface and I
hope it is ready in a few months.

Ah! Now we're getting somewhere! If I understand correctly, then
backsolving is one of BookUp's
many big selling points. If I understand correctly, you are arguing
both here and
on the webpage to which you have provided a link above that compared
with bare statistics,
backsolving is a more reliable indicator of the acuity of a line
because:
"Backsolving also works with computer evaluations. Combined with
overnight analysis, this allows you to create a theory machine that
points out flaws in your repertoire - and discovers new improved
lines." (quoted from your webpage above).
This really is quite an impressive claim! Taken to its extreme, it
appears to me that it might just render Informator redundant, if it
works as effectively as you seem to be suggesting that it does. Around
ten years ago there was a section in Informator headed: "Practice
corrects the estimations" which gave examples, from master play, of
"established" evaluations' having been overturned by some new discovery
in some line or other.
It seems to me to come down to this: how accurate and/or effective does
one consider backsolving combined with the overnight analysis provided
by any number of engines, on the one hand, in comparison with looking
up the theory in the latest Informator or New in Chess Yearbook or
Russian Chess Review or Correspondence Chess Yearbook or even an old
copy of Shakmatny v USSR and conducting analysis oneself, on the other?
Very approximately, what percentage of GMs use BookUp in this way and
to this end, do you think?
What use is BookUp to a patzer, such as I am, for whom learning and
playing a line provided by BookUp and then hanging my
knight/bishop/rook/queen/king appears no different, qualitatively, from
learning and playing a line in a book and then hanging my
knight/bishop/rook/queen/king (been there, done that, got the t-shirt

Right, so duplicates are bad then, I'm glad we cleared up that one. It
took almost a week, but what the heck....
Does BookUp feature a facility which identifies and deletes duplicates
(like, say, the one that ChessBase provides)?

It certainly is! When the concept was introduced, it was called a "theory
machine" and it does make Informator antiquated if not redundant.

That's exactly it. Whether you rely on analysis by an engine or a GM or
both, it must be accurate and complete or Bookup's backsolving is GIGO.

I'd guess 20 percent. I wish I could say it was more. Ultimately they're
all doing it by hand.

I think I got that t-shirt also. :) To a patzer, Bookup is a way to pack
*other* players' backsolved ideas into their heads fast. To leave
patzer-dom behind, one must ultimately become brave enough to create one's
own ideas and improvements and test them. Even if you're wrong, the act of
analyzing with that much responsibility will make you a better player, ala
Kotov's rule about publishing one's analysis in _Think Like a Grandmaster_.

Duplicates may be "bad" but they don't cause Bookup any problems, unlike
with a game database.

>(like, say, the one that ChessBase provides)?
No. In fact, Bookup was published and used for years before it even had the
ability to store and retrieve games. Deleting duplicates is for a game
database.

I've not tried Fritz8 endgame training. Bookup currently handles tablebases
by using Crafty as an engine.
While I've not done a head to head comparison of Fritz8 opening training
with that of Bookup, owners of both have told me that Bookup is way ahead in
that area.

When I say it "just works" I mean that it combines all the games by position
so that copies of the same game don't impact it. With backsolving, just a
single game with the best possible line will overturn a myriad of games with
the second best possible line. More on how Bookup's backsolving is handier

same game) is at http://www.bookup.com/backsolv.htm

I'm not sure what you're asking here. If the general operation of your HDD
slows down, Bookup will slow down. Any database program would.
If you're looking for some odd case of efficiency, then Yes, Bookup would
import the positions from the game once (writing them once to the hard
drive) and then would not bother writing anything to the hard drive for all
the copies of that game since the positions are already imported.

If you're new to databases, Fritz 8 may well provide all you need from
them. You don't mention your rating, but I hope you'll forgive my
assuming that you might be under 2000. If you are, you should study
tactics, by theme. A good way to do this is to access the various
tactics keys which may be generated from the Fritz8 database. If you
want details of how to do this, let me know.
You should also study endgames. It's a good idea to install endgame
tablebases for Fritz8 to use, then to practise the endgame drills which
may be accessed from Fritz 8's board window by clicking
Tools-Training-Endgame Training.
If you can do all of those drills, perfectly, every time, then you're
probably pretty good :-)
If you're an expert (2000) or better, then ChessBase is the way to go.

There's quite a list of what Bookup does that Fritz 8 can't. :)
The biggest thing might be the way Bookup does training. This video

Most sophisticated thing is probably Backsolving. This video describes
that: http://www.bookup.com/chessvideo9.htm

It just works. Since Bookup stores each unique position only once, the only

Does this behave the right way when you have two games that genuinely are
the same? For example, Huebner-Karpov (Tilburg 1986), Sokolov-Karpov
(Bilbao 1987), Ljubojevic-Karpov (Brussels 1987) and Nunn-Karpov
(Skelleftea 1989) all went
1.e4 e5 2.Nf3 Nc6 3.Bb5 a6 4.Ba4 Nf6 5.O-O Be7 6.Re1 b5 7.Bb3 d6 8.c3 O-O
9.h3 Bb7 10.d4 Re8 11.Ng5 Rf8 12.Nf3 Re8 13.Ng5 Rf8 14.Nf3 1/2-1/2
Huebner-Karpov (Torino 1982) is the same except for the transposition
7... O-O 8.c3 d6.

Bookup handles all transpositions instantly, even into the endgame. So the
answer is Yes, it does behave the right way.
Bookup is tremendously useful in studying endings for this reason. Bookup
for the Macintosh was once used to uphold a threefold repetition draw claim
in a US Amateur team match in a very complicated rook ending.

Hi Mike
It's always pleasant to discover a new, free resource on the WWW.
chessopeningspgn.com falls happily into that category. Thus far I have
downloaded (as a test) only A00; with my broadband connection the
download fairly zipped along.
Upon completion, I converted the PGN file to ChessBase 6 format (I have
ChessBase 8) and scoured the database for duplicates. The program found
217, and I found another: game 2 is actually a duplicate of game 3
(Napoleon I and Bonaparte having been one and the same).
Might I suggest a further refinement of your offering, as an option in
a separate set of databases, only games by top players organised by ECO
code?
These are, of course, minor quibbles. Thanks for building the website.

You're very welcome, k. I built the website because *I* wanted to have
something like it available.
