18 Odds and Ends A few things need to be mentioned as a final note. First of all, white-players who have built up their courage to play S .tgS may be in for a disappointment if faced by S ... ttJbd7 or S ... .te7. Both lines may lead to a Classical Queen's Gambit Declined (though Black's early ... c6 is a slight concession) or a Cambridge Springs in the case of S ... ttJbd7. Here this book will not be able to help as these systems are really outside the scope of it. It is worth mentioning that S ... ~b6?! leads Black into some trouble. After 6 ~c2, Black has no good way to justify the queen move, as after 6 ... ttJe4 7 ttJxe4 dxe4 8 cS! he loses a pawn for inadequate compensation. Finally, there is the line 1 d4 dS 2 c4 c6 3 ttJf3 ttJf6 4 ttJc3 e6 S .tgS dxc4 (S ... h6 6 .th4 dxc4 7 e4 gS 8 .tg3 bS 9 eS leads to the same thing) 6 e4 bS 7 eS h6 8 .th4 gS 9 .tg3 (D). This has not been covered so far in the book, and might not be that good but has the practical advantage from White's viewpoint that it can be used against both the Botvinnik and the Moscow Variation. B Black's best is probably 9 ... ttJdS 10 h4 ~a5! 11 :c1 .tb4 12 ~c2 (after 12 ~d2 g4 13 tiJh2 hS Black has achieved a very good version of the Alatortsev Variation!) 12 ... gxh4 13 .txh4 'ii'xa2 and White did not have compensation for the pawn in Gerber-Shabalov, Geneva 1992. There are quieter attempts for White, such as 10 .te2 or 10 ttJd2, but neither promises anything. For a better feeling of this type of position, the reader is invited to 'study Chapter 14, The Anti-Moscow Variation. Here White is very often reluctant to play eS since this loses a lot of his dynamism, whilst it is not that easy to exploit the dark squares.
