As a side note, in 10 days GM Oscar Panno, the Argentine legend, will celebrate the 70th anniversary of his World Junior title. Congratulations $1 8. d4d5  8... c6b8 The modern move. 9. e2e4  9... a7a5  10. a1b1 This move was also played in the first game of the match. Iturrizaga knows this line well: he faced the Brazilian GM Alexandr Fier this year but chose instead the more natural 10.Ne1. 10... b8a6  11. f1e1  11... a6c5  12. b2b3  12... c8d7  13. h2h3 An useful waiting move. 13... h7h6 If he plays h3, I can play h6. This is a good motto, especially in games with fast time controls. It might not be the most accurate, but certainly, it will not be very bad either. 14. a2a3  14... g8h7 This move doesn't help Black's position 15. d1c2  15... b7b6 [%c_effect b6;square;b6;type;Mistake;persistent;true] 16. b3b4  16... a5b4  17. a3b4  17... c5a4  18. c3b5 [%c_effect b5;square;b5;type;GreatFind;persistent;true] The knight is stuck on a4, and Black is already losing. 18... c7c6 A desperate attempt to save the poor knight. 19. b5d6  19... d8c7  20. d5c6  20... d7c6  21. f3e5 [%c_effect e5;square;e5;type;GreatFind;persistent;true] The only path to victory. But one, sometimes, is good enough. 21... c7d6  22. e5c6  22... d6c6  23. e4e5  23... c6e6  24. c1h6 A flashy move, although there is a simpler and equally effective path. 24... f6d7  25. h6g7  25... h7g7  26. g2a8  26... f8a8  27. b1a1  27... d7e5  28. c2e4 [%c_effect e4;square;e4;type;GreatFind;persistent;true] 28... a8e8  29. e4e5 The simplest. 29... e6e5  30. e1e5  30... e8e5  31. a1a4  31... e5e4  32. a4a6  32... b6b5  33. c4b5  33... e4b4  34. a6b6 \"All rook endgames are drawn.\" Unless you are two pawns down. Jokes aside, the endgame is easily winning for White. 34... g6g5  35. b6b8  35... g7g6  36. b5b6  36... b4b3  37. g1f1  37... b3b2  38. f1e1  38... g6f6  39. b6b7 In this position, White has pushed the pawn all the way to b7 and next can create a passed pawn on the other flank. The passer needs to be an f-pawn since g- or h- pawns are not enough to break the resistance. 39... f6g7  40. e1d1  40... f7f6  41. d1c1  41... b2b6  42. c1c2  42... b6b5  43. c2c3  43... b5b1  44. c3d4  44... b1b5  45. d4e4  45... b5e5  46. e4f3  46... e5b5  47. f3g4  47... b5b4  48. g4h5  48... b4b6  49. h3h4 [%c_effect h4;square;h4;type;GreatFind;persistent;true] 49... b6b5  50. h4g5  50... b5g5  51. h5h4  51... g5b5  52. g3g4  52... b5b4  53. f2f4  53... b4b3  54. f4f5  54... b3b4  55. h4h5  55... b4b1  56. g4g5
