Which rejects this  possisbility. Now Black's only hope is the counterplay after:
1. e2e4  1... c7c5  2. g1f3  2... d7d6  3. d2d4  3... c5d4  4. f3d4  4... g8f6  5. b1c3  5... a7a6  6. g2g3 A quiet but not bad line at all against the Najdorf. 6... e7e5  7. d4b3  7... f8e7  8. f1g2  8... e8g8  9. e1g1  9... b8c6  10. h2h3  10... h7h6 "Slightly inaccurate way to move pawns forward" (Anand). 11. c1e3  11... c6a5 The trade of the knight is good for Black as he would not  need to retreat with it once an exchange happens on d5. 12. b3a5  12... d8a5  13. d1d2 With the threat of Nc3-d5. 13... a5c7  14. a2a4  14... c8e6  15. a4a5  15... a8c8  16. f1c1 The key move in this variation and a favorite of  the twelfth world champion Karpov (who picked it up from his great coach  Geller). Instead of mindlessly occupying the half-open d-file, Anand put  the rook where it would actually work. After the white knight jumps on d5, the pawn on c2 would be first of all defended and also supported to move  forward to c4-c5 and beyond. 16... f8e8  17. c3d5  17... e6d5  18. e4d5  18... f6h7 Intending Be7-g5.
