by Alfonso Romero Holmes & Oscar de Prado Rodriguez
New in Chess
http://www.newinchess.com/
335  pages
Price $ 26.95
ISBN: 978-90-5691-689-3



The two chess professionals Grandmaster Alfonso Romero Holmes and his companion FIDE master Oscar de Prado Rodriguez, provide the reader with a impressive
made move to move openings book on the London System, which runs with the moves 1.d4 Nf3 and Bf4.
The London System is simple a set of solid lines where white quickly develops his dark squared bishop to f4 and than bolsters his centre with c3 and e3.
The Pereyra Attack is related to the Argentina chess champion Manuel Pereyra Puebla, who preferred to play a set-up with 1.d4 e6 2.Nf3 Nf6 3.Bf4 d5
4.e3 Bd6 5.Ne5,and this all is considered is chapter 13.
The main basis of this book is a Hugh collection of 64 games, exercises and extra included illustrative games,all packed in 13 intensive chapters.
Covered are London System versus the Grünfeld,King’s Indian,Queen’s Indian,Benoni,Dutch,Slav and various lines as for example the Polish Defence
A fine example of modern play is model game 18: Payen,Arnaud (2325) - Hansen,Eric (2557) [A48]
Cappelle op 29th Cappelle-la-Grande (1), 23.02.2013
1.d4 Nf6 2.Nf3 g6 3.Bf4 Bg7 4.e3 0-0 5.Be2 d6 6.0-0 c5 7.c3 Qb6 8.Nbd2 Bf5 9.Nc4 Qc7 10.h3 Nbd7 11.a4 Rac8 12.Bh2 Be6

63.Kg3 Kf5 0-1,covered with nearly 7 pages of highly instructive text!
The London System is one of the safest and most solid method of handling the white pieces,and is flexible enough to be played under all
tournament conditions and even with correspondence chess!
Conclusion: Very important reference work on the London System!

Reaching the Top?!
A Practical Guide to Master-Level Chess
by Peter Kurzdorfer
2015
Russell Enterprises
304 pages
Price € 22,95
ISBN: 978-1-941270-17-2


Reaching the top is a practical guide from the American chess Master Peter Kurzdorfer how to reach the magical goal of chessmaster,or how
to convert your chess knowledge to the so wanted  2200 ELO level.
This all is readable done with topics as Learning From Past Mistakes ,Choose Openings to Suit Your Style,Handling Material Inequality,Practical
Endgames,How Sound Do Your Openings Need to Be?
When Things Go Terribly Wrong, Overcoming Difficulties and How to Win.
A large amount of material come from the personal experiences of  Peter Kurzdorfer and that makes all even more interesting.
But first some words from the author himself: When I began to play, all this book learning did not immediately translate into wins or a high rating.
Something was missing. I needed the experience of playing. So I played a lot. And still something was missing. I played the strongest competition
 I could find and analysed the games with my opponents and by myself afterwards. And still something was missing. I was not “getting it.”
I had trouble calculating reliable variations over the board, so began playing correspondence games where I could look at each position I analysed
on a chessboard and so see it clearer.
This did strengthen my play, but it was not enough. I played blindfold games so I could learn to see these positions in my head during a tournament game.
There are many games from Peter Kurzdorfer in this book but he has no problems analysing games that did not work so well out for him,as for example the
following game against six time US Champion Walter Browne:
Browne,Walter S (2530) - Kurzdorfer,Peter [D34]
New York op New York (1), 1985
1.d4 d5 2.c4 e6 3.Nc3 c5 4.cxd5 exd5 5.Nf3 Nc6 6.g3 Nf6 7.Bg2 Be7 8.0-0 0-0 9.Bg5 Be6 10.dxc5 Bxc5 11.Rc1 Be7 12.Nd4 h6 13.Bf4 Qb6
14.Nxe6 fxe6 15.e4 d4 16.e5 Nxe5 17.Bxe5 dxc3 18.bxc3 Rad8 19.Qe2 Nd5 20.Rb1 Qc6 21.c4 Qa6 22.Rb5 Bf6 23.cxd5 Bxe5 24.dxe6 Bf6
25.Bxb7 Rd2 26.e7 1-0.
This work is overloaded with instructive tips!
Conclusion: This book truly helps you to become a master in chess!

The Exchange Sacrifice
A Practical Guide
by Sergey Kasparov
2015
Russell Enterprises
252pages
Price € 22,95
ISBN: 978-1-941270-22-6


The well known Grandmaster Sergey Kasparov handles at the hand of a small 200 instructive games the so complicated strategies of exchange sacrifices, usually
these techniques are rarely covered ,so to see a complete study on this subject is a novelty.
All techniques are packed in readable chapters as  Domination, Fighting for the Initiative, Utilizing an Advantage, Launching an Attack against
the King, Reducing Your Opponent’s Offensive Potential, Destroying a Pawn Chain, Building a Fortress and Activating Your Bishop.
Every chapter of this book is overloaded with creative master pieces as for example from the greatest chess player of all time,Garry Kasparov:
Kramnik,Vladimir (2758) - Kasparov,Garry (2851) [D23]
Linares 17th Linares (8), 08.03.2000
1.Nf3 Nf6 2.c4 c5 3.g3 d5 4.d4 dxc4 5.Qa4+ Bd7 6.Qxc4 Bc6 7.dxc5 Bd5 8.Qa4+ Bc6 9.Qc4 Bd5 10.Qc2 e6 11.Bg2 Be4 12.Qc4 Bd5
13.Qh4 Bxc5 14.Nc3 Bc6 15.0-0 Be7 16.Rd1 Qa5 17.Bd2 Nbd7 18.g4 h6 19.Qg3 Qa6 20.h4 Qc4 21.Bf4 Qb4 22.a3 Qxb2 23.Nd4 g5
 24.Nxc6 gxf4 25.Qd3 bxc6 26.Bxc6 0-0 27.Bxa8 Ne5 28.Qd4 Rxa8 29.Qxe5 Rc8 30.Rac1 Nd5 31.Nxd5 Qxe5 32.Nxe7+ Kg7 33.Rxc8 Qxe2
34.Rg8+ Kf6 35.Rd7 Qe1+ 36.Kg2 Qe4+ 37.Kh2 Qc2 38.Kg2 Qe4+ 39.Kh2 Qc2 40.g5+ hxg5 41.Rxg5 Qxf2+ ½-½,
Pleas see that white has thrown all his forces into attack and left his king defenceless. He does not have time for the deadly check Ne7-g8.
All games are well covered with highly instructive text and I can only end with the words,this is honestly  a very instructive written middle game book!
Conclusion: Brilliant work!

The master file on this DVD, the so called tournament file holds 273 entries where a small 19 of them are more than excellent analysed:
A fine example of this all is the following heavy weight : Dominguez Perez,Leinier (2723) - Ivanchuk,Vassily (2710) [C70]
Capablanca Memorial Elite 51st Varadero (5), 13.06.2016
[Stohl,I]
1.e4 e5 2.Nf3 Nc6 3.Bb5 a6 4.Ba4 d6 The Ruy Lopez is not only the Berlin, Marshall and the respective anti-systems! Ivanchuk opts for the deferred Steinitz, a time-honoured system which has already featured in his previous practice, but is relatively rare nowadays.
5.0-0 One of the two main moves. Let's check the alternatives briefly: [5.d4 is the main continuation on move 4 against the Steinitz proper, here it's not too effective due to 5...b5 6.Bb3 Nxd4 7.Nxd4 exd4 8.Bd5 a) 8.Qxd4?? c5 9.Qd5 Be6 10.Qc6+ Bd7 11.Qd5 c4-+; b) 8.c3 dxc3 9.Qd5 (9.Nxc3 Nf6 10.e5 dxe5 11.Bxf7+ Ke7 is at best unclear) 9...Be6 10.Qc6+ Bd7 11.Qd5= is a way to avoid a fight.; 8...Rb8 9.Bc6+ (9.Qxd4 Ne7!? . 10.0-0? c6 11.Bb3 c5-+) 9...Bd7 10.Bxd7+ Qxd7 11.Qxd4 Nf6 12.0-0 Be7 13.Rd1 Qc6 14.Nc3 0-0 15.Bg5 Rfe8 16.a3 h6 17.Bd2 a5 18.Qd3 b4 19.axb4 axb4 20.Nd5 Nxd5 21.exd5 Qb5 22.c4 bxc3 23.Bxc3 Bf6= Mamedov,R (2651)-Adhiban,B (2547) Moscow 2013;
