1. e2e4  1... c7c5  2. g1f3  2... b8c6  3. d2d4  3... c5d4  4. f3d4  4... g8f6  5. b1c3  5... e7e5  6. d4b5  6... d7d6  7. c3d5  7... f6d5  8. e4d5  8... c6e7 8...Nb8 is much more popular, but this is also commonly played. Arjun faced this move in 2023 in a game against Dubov. 9. c2c3 [%c_effect c3;square;c3;type;Interesting;persistent;true] 9... e7f5 [%c_effect f5;square;f5;type;GreatFind;persistent;true] This is the best route for the knight now. 10. a2a4  10... f8e7  11. f1d3  11... e8g8  12. e1g1 This is well-known opening theory, with more than 200 games played in this position. 12... f5h4 A good move, but there are alternatives. The plan is to push the f-pawn and start to move the kingside majority. 13. f2f4  13... a7a6  14. b5a3  14... e5f4  15. c1f4  15... h4g6  16. d3g6 [%c_effect g6;square;g6;type;Inaccuracy;persistent;true] This exchange makes things easier for Black. It's better to preserve the bishops with 16.Bg3 or 16.Be3, when White can fight for the advantage. 16... h7g6  17. a3c4  17... d8c7  18. b2b3  18... b7b6 A new move. Predke probably wanted to prevent a4-a5. He could, however, ignore White's idea and activate his bishop instead: 19. f4e3 This move doesn't look very good, since the bishop was already well-placed on f4. Getting it to d4 isn't so important for the position. Anyway, it's difficult to prove an advantage for White. 19... a8b8  20. e3d4  20... e7g5 [%c_effect g5;square;g5;type;GreatFind;persistent;true] Activating the bishop. 21. c4d2 The knight was ready to be attacked by b6-b5. Now it can go to e4 or f3. 21... f8e8  22. c3c4 [%c_effect c4;square;c4;type;Inaccuracy;persistent;true] White's position becomes unpleasant now. It's important to fight for control of the e-file with 22... g5e3  23. d4e3  23... e8e3  24. f1e1  24... c7c5  25. g1h1  25... c8f5  26. d2f3 [%c_effect f3;square;f3;type;Inaccuracy;persistent;true] This move loses a pawn. 26... f5g4 [%c_effect g4;square;g4;type;Mistake;persistent;true] Now White achieves a comfortable endgame. 27. e1e3  27... c5e3  28. d1d4 [%c_effect d4;square;d4;type;GreatFind;persistent;true] 28... e3d4  29. f3d4  29... g4d7  30. a4a5 I believe this move was played in order to prevent a6-a5, when it's difficult to crack Black's position, but this decision is double-edged. 30... b6b5  31. c4b5  31... d7b5  32. h1g1  32... b5d3  33. a1a4 Preventing Rb4 and Be4, but the rook is misplaced. 33... b8e8 [%c_effect e8;square;e8;type;Inaccuracy;persistent;true] 34. a4b4  34... e8e1  35. g1f2  35... e1e5  36. d4c6  36... e5e2  37. f2f3  37... e2a2 [%c_effect a2;square;a2;type;Mistake;persistent;true] 38. b4b8  38... g8h7  39. b8d8 [%c_effect d8;square;d8;type;Mistake;persistent;true] This gives Black hope again. 39... f7f5 [%c_effect f5;square;f5;type;Inaccuracy;persistent;true] 40. d8d6  40... d3e4  41. f3f4  41... a2g2 [%c_effect g2;square;g2;type;Inaccuracy;persistent;true] 42. d6d8  42... g6g5  43. f4e5  43... g2h2  44. c6d4 The d-pawn is ready to advance and Black is lost. 44... h2a2  45. b3b4  45... g5g4  46. d5d6  46... g4g3  47. d6d7 A simple and human way of winning. The computer indicates an alternative that leads to a much more difficult win. 47... g3g2  48. d8h8  48... h7h8  49. d7d8q  49... h8h7  50. d8g5  50... a2a1  51. d4e2 [%c_effect e2;square;e2;type;GreatFind;persistent;true] The knight prevents the g-pawn from promoting. 51... a1b1  52. e5e6  52... b1b4
