New edition of chess (opening) book

 Just finished a new edition of my (paperback) book

'Better Chess Openings' 

(from beginners to advanced, in different sections).

available at Lulu

The only book which nowadays covers most of all modern opening theory
(based on 'nnue' top engines and other books) in one single book.

New version of the Chess Gambiteer (training) software.

In recent month,  updated the awesome Chess Gambiteer (open source) package (and gambits
in the polyglot book) again.  You can get this free chess training software at:

Chess Gambiteer

(being open source, it's completely free (suitable for chess training).

Ofcourse you also can buy the GM Alterman video series:

GM Alterman gambit videos

but playing around with with the Chess Gambiteer package (play against an engine where
you can set the strength in Elo) or watch mastergames  with gambits, based on Winboard 
and without one combined GUI but simple double clicking on the .bat files should be easy
enough (for most users, and then there is a readme.txt as well ofcourse).

As GM Alterman states (in his book with White gambits), players at lower levels (than GM)
learnmuch more from playing gambits, especially tactics (but also attacking plans) than
simply parroting positional GM games (eg. Ruy Lopez, or Slav). In the old days of
chess it was thought by many players (including Gm's) that you can build up  a positional
advantage with White, if you choose the 'best' opening moves. This turns out to be not 100 pct
solid, if Black defends well, also knowing such lines, you can't get a fundamental advantage 
in the game (for top engines at longer time controls the end result is draw).

Thus playing sharp (often gambit) lines, especially those you know, is a better way to
induce tactical opportunities or exploit possible tacticial mistakes of your opponent in the
game; whereby in blitz it often doesn't matter how sound the gambit is (in the above Chess
Gambiteer package, the gambits in the big book are quite sound, and in the small
(Polyglot) opening book, reasonable sound. And when playing against a weakened engine,
which plays such sound gambits, you first learn defensive skills and then also by learning
those gambits for yourself, you can also practice those gambits against the comp (or online
opponents eg. on chess.com or lichess.org).
Good luck!

Nb in recent two months updated the content of some gambits in my educational book about
chess openings (link below), especially the Smith-Morra. Compared to known theory (and
historical games). It should be now again a higher quality, of importance for those
intermediate players who may choose to play gambits e.g. in blitz or rapid.
Edition 2.04 (July, 2024):

    Kindle version of the book

In general, talking about modernized opening theory (as result of the Nnue engines), besides some recent opening books with 'Modernized' or 'Revisited'  in the title as from Thinkers Publishing in Belgium, i don't know of any other chess opening books which is dealing simultaneously with all new theory at once (which i've done by chosing an optimal repertoire,  at two levels, intermediate or advanced).  You can buy Chessbase 17 ofcourse, for 190 $ or so, but for intermediate players this book (with lots of diagrams) should give sufficient info for opening study at such levels. And it's a lot cheaper too :)

New Edition (opening book)

 The new edition of my chess opening book has arrived!

End December a new version was ready, with everything corrected
according to the new neural net (NNUE) evaluations, and layout
changed/updated (less info for beginners, and the former intermediate
chapter(s) now changed to 'advanced'.

The new intermediate chapters (the former chapter with 1.e4 for 'beginners')
after the updates, now are called the chapters for intermediate players,
more in line with the educational guidelines e.g the Dutch step method
(with mostly only general openig guidelines at the beginners phase).

Although the basic repertoire did not have to be changed,
many moves in variations >5 or 6 ply or so had to be updated.

March 2024: final corrections to the book, the result now
is a high quality, solid opening/repertoire book for all levels of play
(up to IM level or so). 

Ofcourse it's a matter of taste at the advanced levels, what variations
you want to choose for your repertoire, but at least the lines given
in this book are solid, and give high practical chances for achieving
an opening advantage during the opening (if your opponent deviates
from the recommended lines).

E- book available at Amazon Kindle:

New edition of the opening book coming soon

 Next months i am going to  work on the new edition, which will probably take me a few hundred 

hours.  At first, the main updates will be presented in the E-book versions, eg on Amazon

Learning-Chess-Openings-intermediate-levels-ebook (Amazon)

The paper version will get the same updates, but in addition also the comprehensive

appendix with the details of all variations (not in the E-book) will be updated, thus 

making it a timeless reference guide for almost all chess players.  

Note basically, more advanced players will notice it is a 'repertoire' book; because

chess fundamentally is a draw, it is possible the chess players is deviating with his/her

'repertoire'' (built up after beginner level) from the variations in the book(s); however

in some situation we already indicate where such deviations are possible (eg for

more adventurous players,  or sometimes for more advanced players), and in any case

the repertoire given in the new edition of the book will be perfect rocksolid, timeless

and suitable from a practical point of view for the majority of chess players.



Improving opening theory (update of my chess book)

 A few years ago i wrote a book about opening theory specifically aimed

at beginner and intermediate levels; this is/was the paper version of the book:

Better-Chess-Openings (Amazon)

There also is an E-book version (and some other review) with various outlets (eg lulu.com/kobo), but the above  is key. The book was based on chess programs (engines) at that time, which already analyzed positions better  than  human chess grandmasters. However in recent years the chess engines were again considerably improved  due to the use of neural networks (the NNUE approach). As a result I had to check the content  of the book, and the recommended 'repertoire' (main  variations for Black and White). For this purpose in  last two  months I have analyzed two million of the most important opening positions added  the improved results to my computer chess 'opening book' did 'backsolving' some checks and finetuning on the final results. 

Luckily I found that  the  older 'main' opening choices ('repertoire')  still basically are correct (as result  of earlier deep/thorough analysis it appears I  was  ahead of my time) but many variations now do need an update in specific  moves,  and  sometimes  the order  of importance  for specific variations (recommended top choices) will be  changed.  This means it now is time for a  second, completely NEW, improved Edition, based on the latest  ('NNUE')  engines and a systematic analysis of  ALL relevant opening positions starting from scratch. 

Thereby many variations will get an update wrt the specific moves usually from move 3 or 4 onwards, and sometimes  the order of importance for specific variations (recommended top choices) will be changed. An example of a variation  which  has become almost obsolete as result of the engine analysis , is the French Winawer for Black. While I already  not recommended it for Black, I know can list the best moves for White to refute the variation,  in case  Black would play such the -erroneous/outdated- ...Bb4?!.  Also in the chapter with gambits,  and the more advanced 'positional' chapter (with 1.d4) there will be changes in the recommended moves, usually after move 3 or 4 or so, while maintaining the main structure  of the (sub)chapters.

update Chess Gambiteer (open source)

 today uploaded an update of my (gambit) opening training package
at  Sourceforge:

Chess Gambiteer open source application(s)

There are various options available in this package,
1) play against a  engine -with gambit book- at (relatively low) club level, or
2) observe games at higher level (between gambit book
and ordinary book, with two different engines; often yielding
quite interesting and instructive -unbalanced- games).

See the various readme.txt files for more info.

Bookbuilder open source

Announced the open source 'package' (lots of files !) again.
after i added some more instructions (in sources directory
and updated the readme.txt. Announced on talkchess.com (programmers forum).

Some history, the functionality of the program speaks for itself,
decades ago the idea was to use the program not only to study
opening theory, but to improve opening theory itself.

NB not offering support (but you always can try to 'bribe' me
of course if you really get stuck :-)
(no guarantees, however)

PS all this work  resulted in my awesome (paper) chess -openingstudy- book (on lulu) :
https://www.lulu.com/shop/jef-kaan/better-chess-openings/paperback/product-1mw8r8qz.html
with five stars on Amazon.
https://www.amazon.com/Better-Chess-Openings-Jef-Kaan/dp/1326180770/

Meanwhile i used my knowledge to play correspondence chess for some years
on ICCF and acquired a CCM (master) title.

While we are approaching the draw limit in computer chess, i've 
stopped with correspondence chess, at least as long as the (endgame
and 3 pos draw) rule haven't been modified to reduce the draw rate at high levels.

Yet based on the more modern Nnue engines of last year, i'm intending to update
my (paper) book (on Lulu/Amazon) or possibly even write a new edition.

Small update in Bookbuilder book

 In the latest download (bookbuilder setup file), there's now
a slight update of the book.pbs file (more than one million positions)

Best move now is 1.e4 in line with experiences in correspondence chess.
With best play, chess is a draw. but humans still may enjoy the g
game; and become a bit more modest in the process. 

The updated book may be useful for otb players, who like
to check/update their repertoire. But it's not perfect, of  course.

In correspondence chess you may of course look at 
bigger databases/ opening books.

Nevertheless, have fun

:)

new results with updated (Shredder) engine

Now that Deep Shredder 13 came out, somewhere mid/end 2016,
my computer results on the Free Internet Chess Server
(FICS, www.freechess.org) improved again (with an engine, i'm
only allowed to use Shredder on Fics, not Komodo or Stockfish).

With still some other engines ranking higher, i came into to the
top 5 rankings on Fics for blitz, standard, *and* bullet. My opening
book -still used ony with the CP interface) now is about 32 Mb; my
favorite first move for the computer now again is 1.d4, but
sometimes i also play 1.Nf3 (often similar),
1.c4 (sometimes similar), or 1.e4.

Below the nr 4 place recently achieved on FICS:


NB not only is DS13 a much stronger engine, now also the syzygy
endgame bases can be used with the engine (had to adjust some time
settings, due to some time forfeits, maybe because i don't have
an SSD disc yet for these syzygy bases..).

Below the notes for account kec(C) on Fics:

A super-GM repertoire



From my research the English opening (1.c4!) seems a good
first move in top level chess. Although the fundamental differences
between various opening moves are small (*), and a good GM
obviously also tries to look at what the opponent usually plays,
or knows (repertoire). Yet fundamentally, it also matters to know
how theory  develops, for example:

1.c4 e5 (1...c6 leads to Slav2. Nc3 Nf6 3. g3! Bb4! (3...Bc5
4.Nf3! e4 5.Nd4 0-0 6.Bg2 Bxc3 7.dxc3 d6 8.0-0 Re8 9.Nc2
and White maintains a slight advantage.

Otherwise, after 1. c4  Nf6  2. d4 e6 (2...g6 leads to Gruenfeld
or Kings-Indian) 3. Nc3    (g3 also is possible) Bb4!  4. Qc2!  0-0 
(5. e4!?   d5   6. e5   Ne4  7. Bd3  c5 8. Nf3  cxd4  9. Nxd4 Nd7
10. Bf4   Ndc5 11. 0-0  Nxd3=) 5.Nf3! d5 (c5 6.dxc5 Na6 7.g3!
Nxc5 8,Bg2 b6 [...Nce4 9. 0-0 Nxc3 10. bxc3  Be7 11. e4  d6
12. e5  dxe5 13. Nxe5 Qc7 14. Qe2  Bd6 15. Re1 Bd7 16.Bg5!N]
9.0-0 Bxc3  10.Qxc3 Bb7 11.Rd1!  Qe7 12.Qa3! +/=) 6.a3 Bxc3
7.Qxc3 dxc4  
8.Qxc4 b6  9.Bg5  Ba6  10.Qa4  h6 11.Bh4 c5
12.dxc5 bxc5 13.Rc1
+=
And so on; and yes, this is a Nimzo-Indian :)

Alternatively, 1. c4 c5?! (Symmetrical English) 2. Nc3 Nc6  3. Nf3 
g6  4. e3  Nf6  5. d4   cxd4  6. exd4  d5  7. cxd5  Nxd5  8. Qb3
Nxc3  9. Bc4   Nd5  10. Bxd5  e6  11. Bxc6+  5  bxc6  12. O-O
Qd5  13. Be3 +/=


(*) in the end Black can always equalize but it is not always easy

PS fundamentally the moves 1.d4 and 1.Nf3 are just as good, after
1.d4  Black can also opt for the Slav defense; after a few moves
White as (super-) GM probably can best  choose the 'Anti-Moscow'
gambit, where there still is some more  theory to be found. And after
1.d4 Nf6 2.c4 e6 3.Nc3 we get the Nimzo-Indian again after 3...Bb4
(then 4.Qc2! is advised).
After 1.Nf3 (Reti) Black has several choices besides letting White
transpose to Slav, an interesting possibility now is to go for the
Queens-Indian, after 1..e6! 2.d4 Nf6 3.c4 b6 and if you know the
latest intricacies of  this defense, it still can be a very solid defense.

small update (for the chess book)

a few corrections;

Having looked at some transpositions in some more detail, i
will re-arrange some chapters in mybook in the positional
repertoire; after 1.d4 Nf6 2.c4 c6!? 3. Bf4,  Black may still
have some problems after all, although i had analyzed such stuff.
So after 1.d4 Black can probably better play d5! going for the Slav
(2. c4 c6! but then Black can also throw in a dubious  Albin gambit
2...e5 no big deal. And 2.Nf3 still is possible, but then after 2...Nf6
3.c4 c6! Black is going for the solid Slav defense again

Secondly there's another possible improvement, in the Moscow
line, After Bxf6 Qxf6  instead of the neutral 8.e3 because
of the strong defense systems with ...g6!, White might  better
go for the Hastings variation with 7,Qb3!?, although
also then Black can equalize, for example:

1. d4 d5  2. Nf3   Nf6  3. c4  c6  4. Nc3 e6  5. Bg5  h6  6. Bxf6  Qxf6  7. Qb3  a5   8. e3  a4!  9. Qc2   a3  10. b3  Bb4  11. Bd3  Nd7  12. O-O   O-O  13. Rac1  Qe7  14. Ne2   Ra5  15. Ng3 =

so stay tuned,
until the next update

Further explanation of my book(s)

Because of some comments by readers some further
explanation of the underlying thoughts in my book
about chess openings seems worthwile:

First of all, it should be noted that there are several
parts in the book, one especially for beginners in
opening theory (yet knowledgeable about the chess
rules and basic play), one for intermediate players,
and as two extra chapters, one with gambits for White,
and the last one a positional repertoire with 1.d4.

In all chapters the concept of a repertoire has been
applied to reduce the number of variations to learn.
Thereby in the first repertoire, for the beginners,
the primary aim was simplicity, starting with 1.e4
for White, and playing 1...e5 with Black.
Note that the latter, Black repertoire also can be
useful for intermediate players.

In the next chapter, the repertoire for White with 1.e4
has been assembled in such a way that White intends
to play the strongest move, no matter what Black's
response is. These strong moves for White were found
by extensive computer analysis, fine-tuning of the opening
database, and back-solving, during many iterations, as well
as comparing it with opening theory such as described
in many GM books. As result a strong repertoire with 1.e4
has been compiled. The worth of the book can be found
already to a large extent in this repertoire for White, where
many novelties were found, and some conclusions which do
not seem to be known yet in other books. For example
the strategy against the Berlin defense by playing first
Rd1+, and then later h3. Or the move 9.g4! against the
complicated Dragon variation, a move which fundamentally
seems the best, as result of my comprehensive analysis.

The same method was used in the intermediate Black repertoire,
using the more positional French defense as additional weapon,
besides the sharp repertoire with 1...e5 which already was given.
Also here some new results were obtained, e.g. refraining
from the Winawer, because White seems to be able to get
an advantage against this variation. Yet also aiming for
some simplicity, thus having chosen the Burn variation
instead of the more complicated Mac-Cutcheon for Black.

In addition, the gambit repertoire with possibilities
after 1.e4 for sharp play, not only was computer checked,
but assembled after in-depth analysis, and thus may
contain many novelties and surprises for the opponent.
An ideal repertoire for blitz play, or against a weaker opponent.

Finally, the positional repertoire with 1.d4, was mostly
put together with the same principles, aiming for the
strongest variations. Yet more complicated play as with
the Catalan has been avoided, and a rather ' positional'
variation as the Moscow Semi-slav (Bg5 h6 Bxf6) was
chosen instead of the complicated anti-Moscow gambit.
Nevertheless, in those instances that this variation comes
on the board, when Black does not know the strongest defense
(using a later ...g6 move and a fianchetto), White has good
chances of maintaining a slight positional advantage.

Thus this repertoire is intended for the more advanced
players at intermediate players, who now and then like
to play 1.d4 instead of 1.e4,  e.g. against stronger players,
and thus broadening their overall knowledge of openings.

In a next book i might describe the strongest repertoire
in chess, which contains of the Sicilian against e4,
and using 1.d4 d5 2.c4 and a subsequent Catalan or Slav
starting with Nc3 instead of Nf3 as in the current book.
Whereby it should be noted that such theory is still
changing year by year, thus making it quite an endeavour
to aim for the very 'best'  openings, in a book which will
last for years.

The current book however, with the solid and strong
variations, is not expected to be subject to many
fundamental changes again, and thus should last for
decades or longer (in a few instances where I found
a slight improvement in the repertoire, I intend to
update this in further editions; such minor revisions
will not change the overall content of the book (containing
of a kindle version on Amazon, and a paperback version
which contains an appendix with more detailed variations
at the end, sold not only on Amazon but also Barnes&Nobles)

Looking for new programmer(s)

The -now open source- Bookbuilder software (*) has been recently picked up by  a Latvian amateur programmer with (still) some guidance by me...
