 It is a great pleasure for me to announce this lovely work from the great  legendary chess instructor Mark Dvoretsky 1947-2016 who will be
  remembered as one of the greatest chess teachers of all time.
 This man had the talent to bring the complex techniques of chess readable on paper.
 A amassing position, page 93 comes from the following correspondence game where I will give all moves: Marcussi,Bartolome Jorge M - Timmerman,Gert Jan [C91]
 NBC-15 Volmac-A 8286 corr NBC, 1982

Qxf2+ 35.Kh3 Please see also the notes in BCM issue 1/of 1988 p30 1-0,this game did not hold the black player to become the 15th world champion in correspondence chess.
Covered are seven sections: Training combinational vision, Candidate moves, Calculating variations,Attack and defence, Positional play, Realizing an advantage,and at last Endgame test which are good for nearly 20 pages of instructive text!
The foreword comes from Grandmaster Artur Yusupov.
Conclusion: Remarkable read!

Kaufman's New Repertoire for Black and White: A Complete, Sound and User-friendly Chess Opening Repertoire
Larry Kaufman

New in Chess
456 pages
Price € 29,95
ISBN: 978-90-5691-862-0

Kaufman’s New Repertoire for Black and White is not a updated second edition but GM and computer expert Larry Kaufman has completely revised his repertoire from the White side and is now recommending 1.e4 instead of 1.d4 in this brand new heavy weight!
This 2019 release has been  motivated by the so called  MCTS {Monte Carlo Tree Search, a method for computer engines to choose which moves to investigate}revolution, because MCTS engines favour lines that are apt to work in over-the-board play against humans, not just ones intended for correspondence play vs. engines.
As Kaufman explains:  The reason is that normal engines assume "perfect" play by the opponent, while MCTS merely assumes "good" play. My hope was that the analysis would be very different from books that use traditional engines. Of course there are good and bad moves in chess, so there is considerable overlap, but I expect people will see substantial differences from existing theory.
In big lines there are no major changes for black after 1.d4, although the games and analysis are heavily revised. With a lot of included 2019 material.
For Black, the main change is that the Breyer defence to the Spanish is now a backup line, with the Marshall Gambit has  become a important main line,included at last is an extra chapter on the  Moller Defence,a good option as Kaufman explains if Black hopes to have some winning chances without undue risk.
Interesting are the words from Kaufman on the Latvian Gambit 1.e4 e5 2.Nf3 f5? The Latvian Gambit,but I would call it the Latvian blunder, since black gets absolutely nothing for the pawn in the game line or else suffers an awful position to regain it.
And 2…d5 is after Kaufman not so bad as the Latvian it seems because at least black can get some compensation for the pawn in the Elephant.
And in the Spanish Exchange Bobby’s Fischer favourite petline Kaufman prefers 1.e4 e4 2.Nf3 Nc6 3.Bb5 a6 4.Bxc6 dxc6 5.0-0 Bg4! Not bad is 5….Qf6 which is not bad  but also not quite equal.
As we can see in this book the various repertoire systems are all well worked out with high tech chess engines and that makes this book also very useful for correspondence chess!
Conclusion: The perfect chess companion!

Keep it Simple: 1.d4: A Solid and Straightforward Chess Opening Repertoire for White
by Christof Sielecki

New in Chess
423  pages
Price € 29.95
ISBN: 978-90-5691-867-5

The IM from Germany Christof Sielecki providers the local club player and the even  more ambitious chess student with a fine follow up from his well made 1.e4 repertoire book, {Keep it Simple 1.e4 }which we had last year on our website.
This time our author,{Keep it Simple 1.d4},goes in big lines for the easy to memorize move order 1.d4, 2.Nf3, 3.g3,4.Bg2 and 5.0-0.
It looks all very simple but as we can learn from Sielecki,the black player has to stay sharp: Kramnik,Vladimir (2808) – Vocaturo,Daniele (2583) [A49]
Olympiad-42 Baku (11.1), 13.09.2016
1.d4 Nf6 2.Nf3 g6 3.g3 Bg7 4.Bg2 0-0 5.0-0 d6 6.b3 e5 7.dxe5 dxe5 8.Ba3 Qxd1 9.Rxd1 Re8 10.c4 e4 11.Nd4 c6 12.Nc3 Na6 13.e3 Bg4 14.Rd2 Rad8 15.h3 Bc8 16.Rad1 h5 17.Be7 Rxd4 18.Rxd4 Rxe7 19.Rd8+ Ne8 20.Nxe4 Be6 21.Ra8 Be5 22.Rdd8 Kf8 23.Rxa7 Bc7 24.Rda8 Bb6 25.Rxa6 bxa6 26.Nf6 Bd7 27.b4 c5 28.Nd5 Bc6 29.Rxa6 Bxd5 30.Bxd5 Bd8 31.b5 Rd7 32.b6 Ke7 33.b7 Bc7 34.Ra8 Nf6 35.Rc8 Bd6 36.Bc6 Rd8 37.a4 Nd7 38.a5 Bb8 39.a6 Ne5 40.Rxb8 Rxb8 41.Bd5 1-0.
The 6.b3 line and the bishop fianchetto  belongs to one of Kramnik’s favourite lines of this moments  and his results with it are truly more than impressive.
All together these King’s Indian  lines are good for over twenty pages of instructive text!
Covered are also lines as Catalan, Anti Chigorin, Tarrasch Defence,Grünfeld reversed, Dutch, Old Indian and more!
Conclusion: Simple but on the other hand a very dangerous repertoire book!

The Club Player's Modern Guide to Gambits: Fighting Chess from the Get-go

by Nikolai Kalinichenko

Russell Enterprises
93 pages
Price €24.95
ISBN 978-1-941270-76-9

The  renowned theoretician correspondence Grandmaster Nikolai Kalinichenko provides the reader in these 255 pages with a unbelievable collection smashing gambits.
This work holds around 50 major gambits pleasant enough for around 135 complete games, often  included with many extra game fragments.
Even in the time of latest chess engines as Alpha Zero we still play gambit as for example the Marshall Gambit,and often with excellent results:
Ivanchuk,Vassily (2715) - So,Wesley (2762) [C88]
Tata Steel-A 77th Wijk aan Zee (8), 18.01.2015
1.e4 e5 2.Nf3 Nc6 3.Bb5 a6 4.Ba4 Nf6 5.0-0 Be7 6.Re1 b5 7.Bb3 0-0 8.h3 Bb7 9.d3 d5 10.exd5 Nxd5 11.Nbd2 Qd7 12.Nxe5 Nxe5 13.Rxe5 Nf4 14.Nf3 Nxg2 15.Kxg2 a5 16.Rxe7 Qxe7 17.c3 Ra6 18.d4 Rf6 19.d5 a4 20.Bc2 Rd8 21.Qe1 Qd7 22.Ng5 h6 23.Ne4 Rg6+ 24.Kh2 f5 25.Ng3 Qxd5 26.Qg1 Qf3 0-1
14….Nxg2!! is the key point of the black sacrifice, a nice idea indeed! It had been worked out by computers and it had already been tested in tournaments as well, for that reason it is really surprising that Ivanchuk was not aware of that. Nikolai Kalinichenko is not so negative about the Latvian Gambit as our chess friend Larry Kaufmann: Black cannot achieve near equality with correct play by his adversary. He may still have reasonable practical chances if he knows the subject better than his opponent.
A fine example comes  from the Latvian Gambit expert Jonny Hector:
Psomiadis,Stavros - Hector,Jonny (2535) [C40]
Katerini op Katerini, 1992
1.e4 e5 2.Nf3 f5 3.exf5 e4 4.Qe2 Qe7 5.Nd4 Nc6 6.Qh5+ Kd8 7.Nxc6+ dxc6 8.Be2 Nf6 9.Qg5 h6 10.Qe3 Bxf5 11.0-0 Nd5 12.Qd4 Qd6 13.d3 Nb4 14.Qc3 exd3 15.cxd3 Be7 16.a3 Nd5 17.Qb3 Qe5 18.Bf3 Bd6 19.g3 Qd4 20.Bxd5 Qxd5 21.Qxd5 cxd5 22.d4 Kd7 23.Nc3 c6 24.b4 b5 25.Be3 a5 26.Bd2 axb4 27.axb4 Bd3 28.Rfc1 Bxb4 29.Ne4 Bxd2 30.Nxd2 Bc4 31.Nf3 Rhe8 32.Ne5+ Kd6 33.f4 c5 34.dxc5+ Kxc5 35.Re1 b4 36.Nd7+ Kd6 37.Nb6 Rxa1 38.Rxa1 Kc6 39.Nxc4 dxc4 0-1.
Conclusion: A must for all gambit lovers!

[Adhiban, Baskaran]
Until this game my tournament was going pretty well and this one game managed to completely ruin a good event! So it is time to get down to business and figure out what exactly went wrong! 1.e4 e5 2.Nf3 Nc6 3.Bb5 a6 4.Bxc6 I was surprised to face this in two times in 3 months... and only later on during the analysis of this game I came to realize that I have a pretty depressing score here, something which I should paid attention much earlier :). 4...dxc6 5.Nc3!? An interesting choice, since at the moment counting this game my personal score stands at 0% :). [5.0-0 was what Naiditch chose against me which was also analyzed by me in an earlier CBM magazine. 5...Qf6 6.d4 exd4 7.Bg5 Qd6 8.Nxd4 Be7 (8...Bd7 was what I did which is also decent.) 9.Bxe7 Nxe7 10.Nc3 Bd7 This position is quite fine for Black, so I don't know why players keep going for it from white. 11.Nde2 0-0-0 12.Qc1 Ng6 13.Qe3 Kb8 14.Rad1 Qe7 15.f4 Bc8 16.Nc1 Rxd1 17.Rxd1 b6 18.Nd3 a5 19.Re1 Ba6 20.Nf2 Re8 21.a3 f6 22.Ne2 Bb7 23.Ng3 c5 24.Nf5 Qf7 25.Rd1 Nf8 26.c3 a4 27.h3 Ne6 28.Ng3 Bc6 29.Rd2 Nd8 30.Qd3 Nb7 31.Kh2 Nd6 32.Rd1 h5 33.Re1 h4 34.Nf1 Qb3 35.e5 fxe5 36.fxe5 Qxb2 37.Re2 Qb5 38.Qc2 Nc4 39.e6 Nxa3 0-1 (39) Naiditsch,A (2695)-Svidler,P (2735) Karlsruhe/Baden Baden GER 2019] 5...f6 6.d3 [6.d4 exd4 7.Nxd4 c5 8.Nde2 Qxd1+ 9.Nxd1 Be6!? (My other loss in this line continued 9...Bd7 10.Bf4 0-0-0 11.Ne3 Bc6 The bishop is kind of stupid here. 12.f3 Ne7 13.Rd1 Re8 14.Kf2 Ng6 15.Bg3 Ne5 16.h4 h5 17.Bxe5 fxe5 18.c4 Bd7 19.Rd3 Be6 20.b3 g6 21.Ng1 Bh6 22.Nh3 Bxh3 It is never a good idea to give up the bishop pair. 23.Rxh3 Rd8 24.Rxd8+ Rxd8 25.Ke2 c6 26.Rh1 Rd4 27.g3 Kc7 28.Rc1 Kd6 It should be a draw if both players just sit still! 29.Rc2 b5 30.Nd1 bxc4 31.bxc4 Bf8 32.Nb2 Be7 33.Rc3 g5 34.hxg5 Bxg5 35.Rd3 h4 36.gxh4 Bxh4 37.Rxd4+ cxd4 38.Nd3 Bg3 39.c5+ Kc7 40.a4 a5 41.Kf1 Kd7 42.Nb2!

[8...Be6³ was my first intention and I should have gone for it as there was no real need to prevent d4.] 9.Nd2 Be6 10.a4 Qd7!? I just decided to continue developing. [10...a5 seemed to fix the structure unfavourably.] 11.g3 0-0-0 [One of the moves which I wanted to make it work was 11...Ne7!! The key is to feel the right moment to make such a decision! 12.Bxc5 Nc6 13.Bxf8 (13.Be3 0-0-0) 13...Nd4 14.Qd1 Rxf8 looks so nice but I didn't expect that it would be so pleasant for me, while White is just struggling.] 12.a5 h5!? Forcing h4 which would weaken the kingside. 13.h4 Bd6 14.f3 Qc6 15.Nc4 Nf8 Bringing the knight to d4 and here I got bit nervous thinking about stupid things and offered a draw... 16.Nxd6+ Qxd6 [16...Rxd6 was also possible.] 17.Qf2 Nd7 [17...c4 18.dxc4] 18.Na4 [I was expecting 18.b3! where I intended to continue 18...f5 fighting for counter play.] 18...c4 19.dxc4 [I was more concerned about 19.0-0!? , another possibility giving up the pawn and playing for attack.] 19...Bxc4 [19...Qb4+ 20.Bd2 Qxc4 21.b3 (21.Qa7) 21...Qxc2 22.0-0] 20.b3 Bb5 21.Nc3 Qb4 22.Bd2 Qd4 23.Qxd4 exd4 I was quite happy with my position but my spirit wasn't!! 24.Nd5 Here he offered a draw. 24...Rde8 Trying to tempt fate : ). [24...Rhe8 was definitely better! 25.Bf4 (25.Kf2 f5) 25...Ne5 with a nice position for me, though I guess White should be able to equalize.] 25.Bf4! I completely missed this active option for my opponent and after this I am in trouble! 25...Ne5 26.Kf2 And now the d4-pawn might soon wither away. .. 26...c5 27.Rad1 f5 28.exf5 Nxf3 [Good or bad, I had to go for 28...Bc6 29.Nb6+ Kd8 with some chances to save the game.] 29.Kxf3 [29.c4! was just winning on the spot! 29...dxc3 30.Nb6#] 29...Be2+ 30.Kf2 Bxd1 31.Rxd1 Rhf8 32.f6 gxf6 33.Bd6 Rf7 34.Nb6+ Kd8 35.Bxc5 I feel like I lost this game when I offered draw, so that is the biggest learning from this game! 1-0.
Conclusion: Super material for a bargain price!
