Improvements on the Rebel 9 openingbook



 1. Four Knight's   1. e4 e5 2. Nf3 Nc6 3. Nc3 Nf6 4. g3!? 

    Glek-variation for White, 4. d4 has been improved considerably.



 2. Scotch   1. e4 e5 2. Nf3 Nc6 3. d4  strongly improved.



 3. Vienna game for White   1. e4 e5 2. Nc3 Nf6  and now  

    3. Bc4, 3. f4 or 3. g3



 4. Latvian gambit   1. e4 e5 2. Nf3 f5!?  as a new weapon for

    Black. Considered dubious by theory, but very dangerous against

    unprepaired opponents.



 5. Belgrade gambit   1. e4 e5 2. Nf3 Nc6 3. Nc3 Nf6 4. d4 exd4 

    5. Nd5!?  Karpov writes this gambit is far more dangerous than 

    its reputation. White often gets great compensation for the pawn.



 6. Ruy Lopez   1. e4 e5 2. Nf3 Nc6 3. Bb5 a6 4. Ba4 Nf6 5. 0-0 Bc5!?

    and 5 ... b5 6. Bb3 Bc5!?  for Black. The Moller and Neo-Archangelsk

    variations are very popular today. Two of the most developing lines 

    in the Ruy Lopez, by the efforts of f.e. Shirov, Anand, Karpov and 

    Topalov.



 7. Queen's Indian   1. d4 Nf6 2. c4 e6 3. Nf3 b6   greatly improved. 

    New lines for White and Black.



 8. Queen's gambit, Chigorin defence   1. d4 d5 2. c4 Nc6. Often

    leading to non-balanced positions, giving good play for Black. 

    Thanks to the efforts of Morozevich and Ivanchuk this line is 

    becoming more and more popular.



 9. Evans-gambit  1. e4 e5 2. Nf3 Nc6 3. Bc4 Bc5 4. b4!?  as a new 

    weapon for White. THE gambit of the last century, together with 

    the King's gambit! A lot of theory of the old masters, like Lasker, 

    Chigorin, Steinitz and others.



10. Scandinavian   1. e4 d5   With a lot of improvements for White 

    and Black.



11. Queen's gambit, Lasker and Tartakower variations improved.   

    1. d4 d5 2. c4 e6 3. Nc3 Nf6 4. Bg5 Be7 5. e3 0-0 6. Nf3 h6 

    7. Bh4 b6 and  7. ... Ne4



12. Queen's gambit, exchange variation 3. cxd5 or 4. cxd5. 

    Improvements for both White and Black.



13. Queen's gambit with Bf4!  1. d4 d5 2. c4 e6 3. Nc3 Nf6 4. Nf3 

    Be7 5. Bf4!  The modern variation versus the QGD, popularized

    by f.e. Kramnik, Karpov, Topalov, Van Wely and others.  Rebel

    knows all about this line!



14. Semi-Tarrasch   1. d4 d5 2. c4 e6 3. Nc3 Nf6 4. Nf3 c5 a new

    variation for Black, added to the book.



15. Ruy Lopez exchange   1. e4 e5 2. Nf3 Nc6 3. Bb5 a6 4. Bxc6   

    Now more options for Rebel as Black.



16. Sicilian Najdorf,  Fischer's variation added to Rebel's 

    repertoire:  1. e4 c5 2. Nf3 d6 3. d4 cxd4 4. Nxd4 Nf6 5. Nc3 

    a6 6. Bc4



17. Reti  1. Nf3  greatly improved, may new variations for White 

    and Black.



18. English  1. c4  all variations extended and strongly improved. 

    Rebel has about 15 new variations versus the English defence

    in store!



19. Sicilian, the 'new' Alapin, popularized by Adams, Anand and 

    others:  1. e4 c5 2. Nf3 d6 3. c3!?  the new fashion for White!?

    Rebel knows it and plays this with White!



20. French exchange variation.   1. e4 e6 2. d4 d5 3. exd5 exd5  

    and now 4. Bd3 or 4. c4!?  Really that boring!? We don't think

    so. Otherwise Kasparov would not play it as White!



21. Larsen's opening 1. b3  as a new variation for White.



22. A lot of dubious variations are difficult to handle. With the 

    help of the Big book of Busts these variations are now refuted. 

    Don't try it against Rebel, because you'll lose!



23. Last but not least all major improvements and novelties from 

    the last year have been added to Rebel's chess opening knowledge.
