1. d2d4  1... d7d5  2. c2c4  2... e7e6  3. g1f3  3... g8f6  4. b1c3  4... c7c6  5. c4d5  5... e6d5  6. c1f4  6... c8f5  7. e2e3  7... b8d7  8. h2h3 This seemingly harmless system has already been played by many strong players, including Carlsen. With his last move, White, in addition to freeing a square back to the bishop on h2, prepares to play g4 and then possibly Nh4, capturing the bishop. 8... f8b4 This is probably not the most accurate, although it's certainly playable. 9. d1b3  9... d8b6  10. g2g4  10... f5g6  11. f3h4 [%c_effect h4;square;h4;type;GreatFind;persistent;true] 11... b4e7 A new move. The bishop returns to e7 anyway, so it's possible to say that his trip to b4 was not the best, but this is not a big deal. 12. h4g6  12... h7g6  13. f2f3 A typical move to take the e4-square from the knight and be able to take the king to f2. 13... d7f8 Maneuvering the knight to e6. 14. f4g3  14... f8e6  15. e1f2  15... e7d8 [%c_effect d8;square;d8;type;Interesting;persistent;true] With the idea of exchanging bishops with Bc7. The strategy of fighting against the pair of bishops, trying to exchange one of them, is well known. Arjun, however, prevents this with his following two moves. 16. f2g2  16... d8c7  17. g3f2 [%c_effect f2;square;f2;type;GreatFind;persistent;true] 17... c7d6 The bishop made a curious triangulation. It is undeniable that he is better placed on d6 than he was on e7. 18. h3h4  18... b6c7 [%c_effect c7;square;c7;type;Inaccuracy;persistent;true] I don't really like this move, it seems a little superficial. The queen is not well placed on c7 and a potential exchange is not so bad for Black. 19. f1e2 [%c_effect e2;square;e2;type;Inaccuracy;persistent;true] A timid move, uncharacteristic of Arjun. 19... e8g8  20. a1e1 Not the easiest of moves to play, since it's not clear what the rook is doing on e1. It gives the queen the option to go back to d1, something that can be helpful in some lines to attack a knight on h5. White certainly alternatives. 20... b7b5 [%c_effect b5;square;b5;type;GreatFind;persistent;true] Possibly this was Black's plan when avoiding the queen exchange: to begin an advance on the queenside. 21. g4g5  21... f6h5 [%c_effect h5;square;h5;type;GreatFind;persistent;true] 22. f3f4 White prepares f4-f5. A critical moment in the game. 22... h5f4 [%c_effect f4;square;f4;type;Inaccuracy;persistent;true] Black doesn't have enough compensation after the sacrifice. 23. e3f4  23... e6f4  24. g2f1  24... b5b4 [%c_effect b4;square;b4;type;GreatFind;persistent;true] Other moves are worse. 25. c3d1  25... a8e8  26. e2f3  26... e8e1  27. f2e1  27... c7c8 [%c_effect c8;square;c8;type;Inaccuracy;persistent;true] 28. e1d2  28... c8f5  29. d2f4  29... f5f4  30. b3e3 White has managed to stabilize his position and has a material advantage. 30... f4f5 The queen exchange favors White: Black needs to try some activity. Exchanging pieces generally helps the side that has a material advantage. 31. f1g2  31... f5c2  32. e3e2  32... c2f5  33. e2e3 This is a curious moment in the game. Considering that Black is at a disadvantage, why did he decline to repeat moves $2 Maurizzi probably feared an even better move than covering the check with the queen on e2. 33... d6f4  34. e3f2  34... f8e8  35. h1e1  35... e8e1  36. f2e1 It may seem that things are not so simple, after all Black has two pawns for the piece. But all White has to do is improve the knight's position. After this, the weaknesses of Black's pawns will become even more apparent and the win is not difficult. 36... g8h7  37. e1e2  37... f4d6  38. e2d2  38... a7a5  39. d1f2  39... d6c7  40. f3d1  40... f5e6  41. d2d3  41... h7g8  42. b2b3  42... e6d6  43. f2g4 The knight is ready to go to e5 and the material advantage is felt. White's position is winning. 43... d6e6  44. d3e2  44... e6d7  45. e2e3  45... c7b6
