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
Now isn't black simply losing a piece after 10.b3 a5 11.Kb2? True, but deep Rybka analysis shows that black has serious counterchances, 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:
