1. e2e4  1... e7e5  2. g1f3  2... b8c6  3. f1c4  3... f8c5  4. e1g1  4... g8f6  5. d2d3  5... h7h6 A solid move to avoid the always-unpleasant pin on g5. 6. c2c3  6... d7d6  7. a2a4  7... a7a6  8. f1e1  8... c5a7  9. b1d2  9... e8g8  10. h2h3 The positions of the Italian Opening are made up of small subtleties. What's the best plan for Black here: to put the bishop on e6 $2 But is it necessary to place the rook on e8 first, or is it unnecessary $2 What if we move the knight from c6 to g6 $2 These are difficult details that need to be understood. 10... c6e7  11. d2f1  11... c7c6  12. f1g3  12... e7g6  13. c4b3  13... d6d5  14. e4d5  14... f6d5 This is still well-established opening theory. 15. d3d4 [%c_effect d4;square;d4;type;GreatFind;persistent;true] 15... e5d4  16. f3d4  16... f8e8  17. e1e8  17... d8e8  18. b3d5 [%c_effect d5;square;d5;type;GreatFind;persistent;true] The bishop is exchanged for the knight for a good reason. Now Black has an isolated queen's pawn and White's knight is already in its ideal blockading position. 18... c6d5  19. c1e3  19... c8d7 The first new move of the game. 20. d4f5 [%c_effect f5;square;f5;type;GreatFind;persistent;true] 20... a7e3  21. f5e3  21... a8d8  22. d1d4 They say that the queen is not a good blockader, but whoever wrote about that certainly did not refer to this position. It's hard to suggest a better square for the queen than d4. 22... d7c6  23. a4a5 [%c_effect a5;square;a5;type;GreatFind;persistent;true] 23... e8e5  24. a1d1  24... d8e8 [%c_effect e8;square;e8;type;Interesting;persistent;true] An interesting idea, sacrificing the isolated pawn. 25. g3f5 This is better than accepting the gift. 25... e5d4  26. f5d4  26... g6e5  27. g1f1 It's always useful to move the king closer to the center when queens are exchanged. 27... g7g6  28. e3g4 [%c_effect g4;square;g4;type;GreatFind;persistent;true] 28... e5g4  29. h3g4 A classic knight versus bad bishop endgame. It's unclear whether it's objectively winning for White, but the defense is very difficult. 29... g8g7  30. f2f3  30... c6d7  31. d1e1 [%c_effect e1;square;e1;type;Inaccuracy;persistent;true] It's better to keep the rooks on the board. 31... e8e1  32. f1e1  32... g7f6  33. e1d2  33... f6e5  34. d2e3  34... h6h5 [%c_effect h5;square;h5;type;Mistake;persistent;true] 35. g4h5  35... g6h5  36. d4e2 [%c_effect e2;square;e2;type;Mistake;persistent;true] 36... h5h4 [%c_effect h4;square;h4;type;GreatFind;persistent;true] 37. e2f4  37... d7e6 [%c_effect e6;square;e6;type;Inaccuracy;persistent;true] 38. f4d3  38... e5d6  39. e3d4  39... h4h3 [%c_effect h3;square;h3;type;GreatFind;persistent;true] 40. g2h3  40... e6h3  41. d3f4  41... h3e6 [%c_effect e6;square;e6;type;Mistake;persistent;true] The king-and-pawn endgame is losing, a fact that both players missed due to lack of time. 42. f4d3 [%c_effect d3;square;d3;type;Mistake;persistent;true] 42... d6c6 [%c_effect c6;square;c6;type;Inaccuracy;persistent;true] 43. d3c5 [%c_effect c5;square;c5;type;Inaccuracy;persistent;true] 43... e6c8  44. b2b4  44... c8e6 [%c_effect e6;square;e6;type;Mistake;persistent;true] 45. c5d3 [%c_effect d3;square;d3;type;Mistake;persistent;true] 45... c6d6 [%c_effect d6;square;d6;type;Mistake;persistent;true] The last mistake. Black can still defend after 46. d3f4  46... d6c6  47. d4e5  47... c6b5  48. f4e6  48... f7e6  49. e5e6
