1. g1f3  1... d7d5  2. g2g3  2... g8f6  3. f1g2  3... e7e6  4. e1g1  4... f8e7  5. d2d3  5... b8c6 Not a very common idea against the King's Indian Attack. 6. b1d2  6... e6e5 Deac enters the Pirc, down two tempi. Even this approach seems playable. 7. e2e4  7... d5d4 As long as Black does not open the center! 8. d2c4  8... f6d7  9. a2a4 A solid approach by Caruana. 9... e8g8  10. b2b3  10... f8e8  11. h2h4 The plans for both sides are clear. Caruana will try to mate the  opponent on the kingside whereas Deac would try to keep him busy on the  opposite flank. Both players have problematic bishops, locked behind their pawn chains, and need to solve their problems too. 11... e7b4  12. c1g5  Slightly weakening the kingside. 12... f7f6  13. g5d2  13... a8b8 In  preparation of b7-b5. 14. h4h5  14... a7a6  15. a4a5 Once again, Caruana tries to force a small concession by his opponent. 15... d7f8  16. f3h4  16... b7b5  17. a5b6  17... c7b6  18. d2b4  18... c6b4  19. d1d2 The best  development of the attack. 19... b4c6 Deac retreats, but overprotects his center in the process. 20. h4f5 At the end of the day, White decided not to push the h-pawn  further. 20... g7g6 This knight cannot be tolerated. 21. f5h4  21... b6b5  22. c4a5  22... c6a5  23. a1a5  23... b8b6 Protecting the sixth rank. 24. a5a1  24... d8e7  25. h5g6  25... h7g6  26. f2f4  Everything is accordance with the grand strategy: open up the kingside and mate the black king. Deac however prepared well for the second wave of the attack. 26... e7h7  27. f4e5 Opening another file for the white major  pieces. 27... f6e5  28. f1f2  28... h7g7  29. c2c3 Not letting Black a second chance to attack this pawn. The c-file  could be quite useful for White as well. 29... d4c3  30. d2c3  30... f8e6 Deac does not intend to defend passively and transfers his knight instead to the beautiful central outpost. This move,  however, has a concrete flaw. 31. h4f3 Caruana prevents the maneuver and hits the e5-pawn at the same  time. He practically wins that pawn now. How could this be wrong? 31... b6d6  32. a1c1 Not only seizing the file, but defending the queen. 32... c8d7  33. f3e5  33... e6d4 This was the whole point behind Deac's active defense. The  super-knight compensates for the missing pawn as it blocks two white pawns and a bishop! 34. e5d7  34... g7d7  35. b3b4  35... d7g4 Now the black queen also blocks actively. 36. c1e1  36... d6d7 A neat defense! Black correctly covers the seventh rank,  thus preventing any activity. 37. e1e3  37... g4g5  38. c3c1 Now surprisingly, Deac gets a chance to play for  something. 38... g8g7  39. g2h3 The bishop is out just in time. 39... d7e7  40. g1g2 And the  g3-pawn is safe. Nevertheless, White hardly has any realistic chances for  a full point. 40... e8h8  41. e3e1  41... g5h5  42. e1h1  42... h5e5  43. c1b2  43... d4c6  44. h1c1 Allowing the trade. 44... e5b2  45. f2b2  45... c6e5  46. c1d1  46... h8d8 Deac is forcing the pawns forward,  after which he can attack them sideways. 47. d3d4  47... e5c6  48. d4d5  48... d8d6  49. d1f1  49... c6e5 A funny coincidence. Yesterday, Deac also built a rock-solid blockade with a knight versus a bishop. In today's game though he still has the  rooks on board and defends actively. And he is down only one pawn. 50. h3e6 This allows the activation of the black rooks, but Caruana hardly had any other choice. 50... e7c7  51. f1a1  51... c7c4  52. b2a2  52... c4e4  53. a2a6  53... d6a6  54. a1a6  54... e4b4  55. g2f2 Almost everything disappeared and the game slowly peters out into a draw.  55... b4a4 Once again active defense. 56. a6b6  56... a4a2  57. f2f1  57... e5c4  58. b6b5  58... g7f6  59. f1e1  59... c4d6  60. b5b3
