comment: It's hard to break Black's position, but White can try for a long time without much risk (although in a blitz game there is always some risk). The plan is to push f2-f4 at the right moment.
context: 1. e2e4  1... c7c5  2. g1f3  2... d7d6  3. d2d4  3... c5d4  4. f3d4  4... g8f6  5. b1c3  5... a7a6  6. f1e2  6... e7e5  7. d4b3  7... f8e7  8. d1d3 This idea was played several times during the match. It's a relatively uncommon move within the gigantic world that is the Sicilian Najdorf. 8... c8e6  9. c3d5  9... e8g8 Black waits before capturing the knight. 10. a2a4 I only found one game with this move. 10... b8d7 A new move. 11. c2c4 White's idea with a4 and c4 is to discourage the typical b7-b5 pawn break, although it's still possible. 11... a6a5 A difficult decision. 12. c1e3  12... b7b6 A logical plan to keep the queenside closed. 13. e1g1  13... d7c5  14. b3c5  14... d6c5 The plan is to take on d5 and defend a passive position without pawn weaknesses. 15. a1d1  15... e6d5  16. c4d5  16... e7d6
