Can you tell where the turning point of the game is, i.e, where Junior went >wrong and what it could have played. > >thx Looks like a flaw in Junior's book line where CM9000 came up with a novelty, its own book having ended a couple of moves earlier. The Sicilian volume of the Encyclopaedia series (a Russian equivalent to ECO) indicates that CM's 16...Rab8 had been considered an error allowing White a slight advantage, citing a game Tverskaya - Larsson, Moscow 1994, which continued 17. b3 Rfc8 18. Bxf5 gxf5 19. Bd4 Qc7 20. Qb2 e5 21. Bf2 Rb4 22. c4. So CM's novelty with 17...Qc6 seems to make 16...Rab8 preferable to 16...Rfb8, which had been thought better, but only good enough for equality. However, Junior's 12. Nxd5 is not as highly regarded as 12. Bd4, while 15. b3 is more mainline than Junior's 15. Qa3, likewise 16. Ba6 is given first, with 16. Bd3 in parentheses. And ECO shows only 16. Ba6, while NCO shows only 16. Bd3 Rfc8. Regards, Vine Smith
