That creates a concrete threat, and it is Saric's moment to be aware of the danger.
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. c1e3  8... c8e6  9. c3d5  9... b8d7  10. d1d3 There was a burst of popularity in this line four years back. Even the world champion gave it a try in a couple of games. 10... e6d5 The most natural choice and the main line. 11. e4d5  11... a8c8  12. e1c1 Sacrificing a pawn. 12... d7b6  13. c1b1  13... e8g8 Which Saric decided to reject. 14. e2f3  14... b6c4  15. e3c1 [#] 15... d8d7  16. h2h3 Preparing not only g2-g4, but often threatening with Bf3-g4! 16... d7a4 This stops the latter and creates a threat in return. 17. h1e1 Najer is aware of the danger. 17... e7d8  18. g2g4 Next White's attack developed much more convincingly. After all, his pieces are not standing on the road of his pawns. 18... f8e8  19. f3e4  19... g7g6  20. f2f3  20... f6d7  21. h3h4 A purely positional pawn sacrifice. For the material Najer will build an attacking blockade. 21... d8h4  22. e1g1 Another neat move. 22... h4f6  23. g1h1 There is no rush, just pure smothering power. 23... f6g7  24. h1h3  24... d7f8  25. d1h1 Only the queen is left to join the kingside attack and is ready to follow with Qd3-e2-h2. Thus, Saric tries to prevent this with: 25... a4b5 Now comes another fabulous decision by the former European champion: 26. b3d2  26... c4b6 Black does not have much of a choice. 27. d3b5  27... a6b5  28. d2f1 White simply follows his plan. 28... e8d8  29. c1g5  29... d8d7  30. b2b3 Najer wants to control everything, and this is a great thought, but the reality is slightly different. 30... d7c7  31. g5d2  31... b6d7 An important resource. The knight is back in the game. 32. e4d3  32... e5e4 Time to unblock! The black knights are starting to enjoy life again. 33. f3e4 The better choice. 33... d7c5 Next a forced sequence: 34. d2a5  34... c7e7  35. f1d2  35... c5d3  36. c2d3  36... f8d7  37. a5b4  37... d7c5  38. h3h7 Leads to a pawn gain for White. 38... c5d3  39. b4d6  39... e7d7  40. d6g3  40... b7b6  41. g4g5  41... c8c3 It seems as Black is out of the woods, but there comes:
