Modern Chess Opening Repertoire for White
by James  Rizzitano

Gambit Publications Ltd
175 pages
Price €21,43
ISBN (13 digits):

The well known International Master James Rizzitano provides  the reader with a one volume repertoire book,based on the famous Giuoco Piano,one of the earliest recorded methods of opening a game.
But it is all played throw the  Bishop’s Opening starting with 1.e4 e5 2.Bc4.
As Tim Harding one wrote: The  Bishop’s Opening is more than a main line with sub-variations.
Other covered repertoire lines are,Modern Advance Caro-Kann,Tarrasch French,Rossolimo,Moscow Sicilians etc.Included with well thought repertoire lines against The Scandinavian and Alekhine
Interesting to mention is the sharp move order against the Pirc and Modern Defence,1.e4 d6 2.d4 Nf6 3.Nc3 g6 4.Bf4 Bg7 5.Qd2 0-0 6.Bh6 c6 7.h4 e5 8.Bxg7 Kxg7 9.h5 Nxh5 10.Be2 exd4 11.Qxd4+ Qf6 12.Qd2 Qf4 13.Bxh5 gxh5 14.Rxh5 f6 15.Nge2 gives white a structural advantage, Jablonicky – Kostolansky,Slovakian Team Ch 2019/20,strange enough not even mentioned in the latest Mega Datatbase!
The move 1.e4 e5 2.Bc4 f5 gets a interesting remark  from the great  Gary Lane in his famous book The Bishop’s Opening Explained,but Rizzitano waves it all away with 3.d4 exd4 4.Nh3!
Rarely played but very effective,4...Nf6 5.e5 Ne4 6.0-0 Nc6 7.Re1 Nxe5 8.Rxe4 fxe4 9.Qh5+ Ng6 10.Bg5 Be7 11.Nf4 d5 12.Nxg6 Bg4 13.Qxg4 hxg6 14.Bxe7 Qxe7 15.Bxd5 e3 16.Qe4 and white’s two minor pieces are far superior to black’s rook plus pawn.
As James Rizzitano explains in his introduction the goal of this book is to provide the reader with a one volume theoretical sound dynamic opening repertoire.
And where Rizzitano goes for a relatively safe king,and suggests the following strategies:Take the bishop-pair in a semi-open position if it is offered to you,Avoid creating unnecessary weaknesses in your own position,Accept questionable gambits and material sacrifices and Absorb any space advantage conceded by the opponent.
Going throw this book you will feel the influence of Alpha Zero related chess engines as Stockfish 13 and 14.
Conclusion: Outstanding repertoire book!
For the interested readerthere is on a interesting introductory video by GM John Nunn!

ChessBase Magazine issue 205 is divided to the legendary Robert Huebner,as the
editorial team describes him as the razor sharp analyst and former world player.
A great talent who fought at the age of 23 for the world championship.
Included on this DVD is a heavy loaded file of 19 entries where I would like to show
 the reader the following win.
Huebner,Robert (2615) - Kasparov,Garry (2780) [E69]
Dortmund Dortmund (6), 23.04.1992
[Müller, Karsten]
Defeating a reigning
World Champion is always something special.
 Here, on top of that, Hübner manages a victory in typical Kasparov style. He relies on his chances in the kingside attack and is rewarded.
 Einen amtierenden Weltmeister zu besiegen, ist immer etwas Besonderes. Hier gelingt
 Hübner obendrein eine Sieg in typischem Kasparovstil. Er setzt auf seine
Chancen im KÃnigsangriff am KÃnigsflügel und wird belohnt.
 1.d4 Nf6 2.c4 g6 3.g3 Bg7 4.Bg2 0-0 5.Nc3 d6 6.Nf3 Nbd7 7.0-0 e5 8.e4 c6 9.h3 Qb6?!
Objectively, this is probably too provocative. However, at the time it was considered well
playable. Objektiv ist das vermutlich zu provakativ. Damals galt es jedoch als gut spielbar.
 10.c5! dxc5 11.dxe5 Ne8 12.Na4? However, this is too slow. Das ist jedoch zu langsam. [Today's main variation Die heutige Hauptvariante 12.e6 fxe6 13.Ng5 Ne5
14.f4 Nf7 15.Nxf7 Bd4+ 16.Kh2 Rxf7 17.e5 is better for White and has discredited the whole play. ist besser für WeiÃY und hat das ganze Abspiel in Misskredit gebracht.] 12...Qa6 13.Bg5 b5 14.Nc3 Nc7 15.Be7 Re8 16.Bd6 Ne6 17.a4 b4 18.Ne2 Qa5! Kasparov also plays for a win as usual and wants more than Kasparov spielt ebenfalls wie gewohnt auf Gewinn und will mehr als [18...c4 19.Bxb4 Nxe5 20.Nxe5 Bxe5 21.Bc3 Bxc3 22.bxc3 Nc5÷ (Knaak in CBM 29), which should be fairly even. (Knaak in CBM 29), was ziemlich ausgeglichen sein dürfte.;
Not, however, the rushed Nicht jedoch das überhastete 18...Qc4? 19.Re1 Qa6 20.a5 c4 21.Nf4 Nef8 22.Bf1±] 19.Nd2 Ba6 Kasparov spurns the pawn and goes fully into his counterplay. Kasparov verschmäht den Bauern und setzt voll auf sein Gegenspiel. [19...Nxe5!? was also strongly in question, though, e.g. kam allerdings ebenfalls stark in Frage, z.B. 20.f4 Nd7 21.e5 Ba6 22.Rf2 Rad8³] 20.f4 c4 21.Kh2 Rad8 [21...Nb6? 22.f5,] 22.Qc2? There is no real progress on the queenside. Am Damenflügel geht es nicht recht weiter. [22.Nf3 was called and the game should balance, e.g. war angesagt und das Spiel sollte sich die Waage halten, z.B. 22...Bf8 23.Ned4 Nxd4 24.Nxd4 Bb7 25.Nc2 b3 26.Ne3 Ba6 27.Rc1 c3 28.Rxc3 Bxf1 29.Qxf1 Qxa4 30.Bxf8 Rxf8 31.Qc1©] 22...Nb6 23.Rfd1 Bf8? After that Hübner's play on the kingside gets going after all. Danach kommt Hübners Spiel am KÃnigsflügel doch noch in Schwung. [After Nach 23...c5! 24.Bf1 Rc8³ (Hübner in CBM 29), on the other hand, it is slowed down. (Hübner in CBM 29) ist es dagegen ausgebremst.] 24.Nf3 c3 25.Ned4 Now it's getting really uncomfortable. Hübner strengthens his initiative in the style of Kasparov, who now plays wrong under pressure: Nun wird es richtig ungemütlich. Hübner verstärkt seine Initiative im Stil Kasparovs, der unter Druck nun fehlgreift: 25...Nxd4? This exchange only increases the white attacking harmony. Dieser Abtausch erhÃht nur die weiÃYe Angriffsharmonie. [25...cxb2! keeps the damage in check, e.g. hält den Schaden in Grenzen, z.B. 26.Qxb2 (26.Nb3? bxa1N 27.Rxa1 Bd3 28.Qxd3 Nc5-+ (Hübner) (Hübner)) 26...Nc4! 27.Qa2 Nxd6 28.Nxc6 Qb6 29.Nxd8 b3 30.Qb1 b2 31.Nxe6 bxa1Q 32.Qxa1 Rxe6 33.exd6 Rxd6 34.Rxd6 Qxd6 35.e5 Qb4²] 26.Nxd4 cxb2 27.Qxb2 [27.Nb3? bxa1N 28.Rxa1 Rxd6 29.Nxa5 Rd3©] 27...Nc4 28.Qb3? Surprisingly, this is the wrong square. Ãoberraschenderweise ist das das falsche Feld. [After Nach 28.Qa2! Black's back is against the wall: steht Schwarz mit dem Rücken zur Wand: 28...Nxd6 (28...Qb6? 29.a5 Qb7 30.Bxf8 Kxf8 31.e6+-) 29.Nxc6 Qb6 30.Nxd8 b3 31.a5 Qe3 32.Qa4 Bb5 33.Qd4 Qxd4 34.Rxd4 Nc4 35.Rb1 Nxa5 36.Rd5 Bc4 37.Rxa5 Rxd8 38.Rxa7 Rd2 39.Rb7±] 28...Qb6 The correct parry of the threat Nxc6. Die richtige Parade der Drohung Sxc6. [Not, however Nicht jedoch 28...Rc8? 29.Bxf8 Rxf8 (29...Kxf8 30.Rac1 c5 31.Nf3 Red8 32.Rxd8+ Qxd8 33.Rxc4 Bxc4 34.Qxc4+-) 30.e6 c5 31.Nf3 Nb6 32.e7 Rfe8 33.Qb2 Nc4 34.Qf6 Qb6 35.e5 Bb7 36.Rd6 Qc7 37.Rc1 Ne3 38.e6 fxe6 39.Qxe6+ Kh8 40.Rd7 Qc6 41.Qe5+ Kg8 42.Rxb7 Qxb7 43.Qxe3 Qxe7 44.Ne5+-] 29.a5 Qb7 However, this decision by Kasparov can also be seen critically. The passive retreat on the queenside gives Hübner a dangerous initiative. Diese Entscheidung Kasparovs kann allerdings auch kritisch gesehen werden. Der passive Damenrückzug gibt Hübner eine gefährliche Initiative. [Presumably Vermutlich war 29...Nxa5!? was the better choice from a practical point of view, e.g. aus praktischer Sicht die bessere Wahl, z.B. 30.Rxa5 (30.Qa4 Bxd6 31.exd6 Rxd6 32.Qxa5 Qxa5 33.Rxa5 Bb5 34.e5 Rd7 35.Rxb5 cxb5 36.Bc6 Red8 37.Bxd7 Rxd7 38.Kg2 b3 39.Kf3 a5 40.Ke4 a4 41.Rb1 Kf8 42.Nxb5 Rb7 43.Na3 b2 44.Nc2 Rb3 45.g4 a3 46.Nxa3 Rxa3 47.Rxb2 Rxh3=) 30...Qxa5 31.Bxf8 Rxd4 32.Rxd4 Rxf8 33.e6 Qc5 34.exf7+ Rxf7 35.Rxb4 Bb5²] 30.Bxf8 Kxf8 31.e6!? The consistent continuation of the white attack. Die konsequente Fortsetzung des weiÃYen Angriffs.

Presumably Kasparov can still hold on, but on the board the defence is hard to find or conduct: Nun ist eine sehr kritische Lage entstanden. Vermutlich kann Kasparov sich noch halten, aber am Brett ist die Verteidigung kaum zu finden bzw zu führen: 34...Rxd1? That's the wrong order. Das ist die falsche Reihenfolge. [34...Nxe5! was called for, e.g. war angesagt, z.B. 35.Qxf7+ Nxf7 36.Nxd8 Rxd8 37.Rxd8+ Nxd8 38.Rc1 c4 (38...Ne6? 39.Bd5 Ke7 (Hübner) (Hübner) 40.g4 Nd4 (40...Nxf4?! 41.Rxc5 Kd6?! 42.Rc6++-) 41.f5 gxf5 (41...b3 42.f6+ Kxf6 43.Rxc5±) 42.gxf5 Bd3 43.f6+ Kxf6 44.Rxc5±) 39.Bf1 b3 40.Bxc4 b2 41.Rd1 b1Q 42.Rxb1 Bxc4 (Hübner) (Hübner) 43.Rc1 Bb5 44.Rc8 Ke8 45.Rc7 Nc6 46.Rxh7 a6²] 35.Rxd1 [35.Qxd1?

Auf diesen Konter hatte sich Kasparov vermutlich verlassen. 37.Qc2 Ng4+? But now he liquidates into a lost endgame under enormous pressure. Nun wickelt er unter den enormen Druck allerdings in ein verlorenes Endspiel ab. [After Nach 37...b3? 38.Qc1 a) 38.Qc3?
