Poisoned Pawn: easy equality for Black!
In 2007 the Poisoned Pawn variation of the Sicilian Najdorf was experiencing
a crisis. White players found out that after 1.e4 c5 2.Nf3 d6 3.d4 cxd4 4.Nxd4
Nf6 5.Nc3 a6 6.Bg5 e6 7.f4 Qb6 8.Qd2 Qxb2 9.Rb1 Qa3 the old move 10.e5!?
was not so easy for black and they scored a few impressive victories. The Poisoned
Pawn finally refuted? Not really! After 10.e5!? h6 11.Bh4 dxe5 12.fxe5
Black has a move that gives him full equality: 12... Nd5!
The Rybka 3 opening book provides you with full coverage of this new, fascinating
line. Including one of the most dangerous white tries, 12... Nd5! 13.Nxd5
exd5 14.e6!? The verdict: black is equalising without any problems!
English attack: no white advantage!
In one of the most complicated lines in the English attack of the Sicilian
Najdorf black faced some real problems recently. After 1.e4 c5 2.Nf3 d6 3.d4
cxd4 4.Nxd4 Nf6 5.Nc3 a6 6.Be3 e5 7.Nb3 Be6 8.f3 Be7 9.Qd2 O-O 10.O-O-O Nbd7
11.g4 b5 12.g5 b4 13.Ne2 Ne8 14.f4 a5 15.f5 a4 16.Nbd4 exd4 17.Nxd4 b3 18.Kb1
bxc2+ 19.Nxc2 Bb3 20.axb3 axb3 21.Na3 Ne5 22.h4 Ra4 the move 23.Rh3!?
seemed to spoil all the fun for black. The point is, that after 23... Qa8
24.Qd5 black seems to have no other choice than entering a worse endgame
after 24... Qxd5.
There is however a solution: 24... Rxa3! Extensive analysis in the Rybka
3 opening book will show you that White has no advantage after this surprising
exchange sacrifice. Also watch the very interesting alternatives 23.Bd4!?
and 23.Qc3!? with enterprising and spectacular play and chances for both
sides. Update your English attack repertoire with Rybka’s new opening book!
A surprising new idea in the Petroff
The Petroff is a very reliable defence against 1.e4 and many white players
have difficulties to prove even an edge against black’s solid setup. In the
past few years new ideas have been tried, one of them being 1.e4 e5 2.Nf3
Nf6 3.Nxe5 d6 4.Nf3 Nxe4 5.Nc3. After 5... Nxc3 6.dxc3 Be7 7.Bf4 Nc6
8.Qd2 white intends to castle queenside. The Dutch IM Van Delft kindly provided
the following idea for the Rybka 3 opening book, which seems to be incorrect
at first sight: 8... Be6 9.O-O-O Bxa2!?
Now isn’t Black simply losing a piece after 10.b3 a5 11.Kb2? True, but
deep Rybka analysis shows that Black has serious counter chances, which are
not to be underestimated! Want to know more about this very interesting idea?
The new Rybka 3 opening book covers the line in detail and shows you how to
deal with White’s tries to refute the piece sacrifice.
A revival of the sharp Botwinnik semi Slav?
The Semi Slav is a very popular defence for Black when facing 1.d4. At the
moment the line 1.d4 d5 2.c4 c6 3.Nf3 Nf6 4.Nc3 e6 5.Bg5 is in the centre
of attention, with 5... h6!? being Black’s main choice. The very sharp Botwinnik
variation 5... dxc4 6.e4 b5 7.e5 h6 8.Bh4 g5 9.Nxg5 hxg5 10.Bxg5 Nbd7 11.exf6
Bb7 12.g3 c5 13.d5 is now less popular, but is this decline in popularity
deserved? The Rybka 3 opening book shows that the following line is fully acceptable
for black: 13... Nxf6 14.Bg2 Bh6!
Current analysis shows that black has no problems to keep the balance. Update
your Semi Slav and Meran theory with Rybka’s new opening book!
English Attack: a stunning rook sacrifice
The sharp English attack featuring 6.Be3 is still one of White’s most dangerous
tries against the Sicilian Najdorf. In 2007 Black found a stunning idea in one
of the main lines, first seen in the 5th PAL/CSS Freestyle tournament. After
1.e4 c5 2.Nf3 d6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3 a6 6.Be3 e5 7.Nb3 Be6 8.f3 Be7
9.Qd2 O-O 10.O-O-O Nbd7 11.g4 b5 12.g5 b4 13.Ne2 Ne8 14.f4 a5 15.f5 Black
played the curious 15... Bxb3!? 16.cxb3 a4 17.bxa4 Rxa4 18.Kb1 reaching
the following position:
Here Black uncorked the fantastic move 18... Rxa2! Subsequent computer
analysis proved that the sacrifice is fully correct. Now should white decline
the offer with 19.Nc1, or can he try 19.Kxa2 Qa8+ 20.Kb3? The
new Rybka 3 opening book provides you with in depth analysis of this line and
gives you the answer to both questions. Update your English Attack repertoire
with the new Rybka 3 book!
Sicilian Sveshnikov: a new idea to avoid equality
At grandmaster level the positional variation is by far the most popular try
against the Sicilian Sveshnikov. After 1.e4 c5 2.Nf3 Nc6 3.d4 cxd4 4.Nxd4
Nf6 5.Nc3 e5 6.Ndb5 d6 7.Bg5 a6 8.Na3 b5 9.Nd5 Be7 10.Bxf6 Bxf6 11.c3 White
plays a purely positional game, black’s main answer being 11... O-O. Less popluar
is the alternative 11... Bg5 12.Nc2 Rb8!?, mainly due to 13.a4 bxa4
and white continues with 14.Ncb4 Nxb4 15.cxb4 Bd7 16.Bxa6 O-O 17.O-O Bc6 18.Rxa4!?
But is this exchange sacrifice really dangerous for Black? Rybka analysis shows
that white has no advantage and Black draws easily! The Rybka 3 opening book
proposes a relatively new idea in this theoretical position: 14.Nce3!?
Do you want to know more about this new idea? The new Rybka 3 book covers all
the interesting ideas for Black and White.
Another sharp line in the popular Slav
In the Slav defence the pawn sacrifice 1.d4 d5 2.c4 c6 3.Nc3 e6 4.e4!? dxe4
5.Nxe4 Bb4+ 6.Bd2 Qxd4 7.Bxb4 Qxe4+ 8.Be2 has been very popular lately.
Black used to be in good shape, but white players have found new ideas which
makes the line attractive and dangerous at the same time.
The new Rybka 3 opening book covers this sharp pawn sacrifice in detail and
shows some new ideas as well. Update your Slav repertoire with the new Rybka
3 book!
The Ruy Lopez Zaitsev: white’s most agressive try
With the Marshall and Anti-Marshall systems being the most popular Ruy Lopez
lines at the moment, the complicated Zaitsev variation deserves attention as
well. White’s most agressive try is undoubtedly 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.Nbd2 Bf8
12.a4!? Play usually develops 12... h6 13.Bc2 exd4 14.cxd4 Nb4 15.Bb1
c5 16.d5 Nd7 17.Ra3 c4, leading to the position in the diagram:
The new Rybka 3 opening book gives an overview of White’s main try 18.Nd4,
as well as the interesting sideline 18.Ree3!? Apart from known theoretical
examples many new ideas are added, often leading to exciting positions and chances
for both sides. Update your Zaitsev theory with the new Rybka 3 book!
The popular and complicated Moscow Gambit
Currently the Moscow Gambit is one of White’s most popular tries to combat
the black Semi Slav. After 1.d4 d5 2.c4 c6 3.Nf3 Nf6 4.Nc3 e6 5.Bg5 h6 White
sacrifices a pawn by 6.Bh4 dxc4 7.e4 g5 8.Bg3 b5. The gambit is played
at the highest level and gives rise to spectacular and interesting play.
The Rybka 3 opening book covers the line in detail. Discover the fine ideas
for both sides. The new Rybka 3 book is computer checked, thoroughly tested
and contains many original computer analyses!
The ever popular Sicilian Najdorf
The Sicilian Najdorf enjoys great popularity and has been played by many top
players: 1.e4 c5 2.Nf3 d6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3 a6. Theory of this
variation still develops in a very fast way, new ideas are found, dangerous
White tries are countered by clever black counter-blows.
The Rybka 3 opening book covers the Sicilian Najdorf in detail and has many
new computer lines included. Variations that are thoroughly computer checked
with very fast machines and the best engines! Discover fresh, exciting and clever
ideas for both sides in the English Attack (6.Be3) and the very sharp
main lines 6.Bg5. The new Rybka 3 book is a must for every Najdorf player!

The Milov vs. Rybka Handicap Match
24.09.2008 – The chess program Rybka has played
a number of handicap matches against titled players, but never before
one against a 2700+ player. Last week it got an opportunity against Vadim
Milov, playing two regular games, two with pawn and move handicap and
four with exchange odds. It was a well-matched battle, instructive for
both the programmers and the Super-GM. Larry
Kaufman reports. |

Rybka vs Meyer – pawn and two move handicap match
14.08.2008 – Before the rating system players
were generally classified by the handicap a stronger player could give
them. The chess program Rybka has a higher rating than any human, and
recently it beat GM Roman Dzindzichashvili in a pawn and move handicap
game. Would it be able to acquit itself similarly against an IM who got
a pawn and two moves handicap? It
would and it did. |

The Dzindzi – Rybka 3 Handicap Match
09.08.2008 – Chess with material handicaps
was played by Philidor, Staunton, Morphy and Steinitz. Particularly popular
was “pawn and move”, with Black missing his f7 pawn. Naturally you find
the grandmaster playing the handicapped side. But can a strong GM beat
a computer when playing with the handicap pawn and move? Roman Dzindzichashvili
tried it against Rybka 3.0. IM
