[%c_effect b2;square;b2;type;Mistake;persistent;true] Giving White another chance.
1. c2c4  1... e7e6  2. b1c3  2... d7d5  3. d2d4  3... g8f6  4. c4d5  4... e6d5  5. c1g5  5... f8e7  6. e2e3  6... h7h6 The Queen's Gambit Declined is probably the classical defense that has changed the most in recent years, with new plans for the black side being discovered. 7. g5h4  7... c8g4 [%c_effect g4;square;g4;type;Interesting;persistent;true] A surprising and fresh idea. In the long history of this defense that has been played for ages, this is not an easy feat. This move was played by Carlsen in 2023, and no doubt its theory will develop quickly. 8. d1b3 The critical reply, threatening the pawns on b7 and d5. If White is not going to take on b7, however, it probably makes more sense to develop the queen on c2 immediately. 8... b8d7 [%c_effect d7;square;d7;type;GreatFind;persistent;true] 9. h2h3  9... g4e6  10. f1d3  10... c7c5  11. b3c2 It's clear that something didn't work well for White in the opening. Black has a fine position. 11... c5c4 This advance is never an easy decision in this structure. 12. d3f5  12... e6f5  13. c2f5  13... e8g8  14. g1e2  14... g7g6 It's natural to remove the queen from its advanced post, but Black can seize the chance to advance the queenside. 15. f5f3  15... d8b6  16. e1g1  16... g6g5  17. h4g3  17... b6e6 An interesting plan to defend the d5-pawn. 18. g3h2 [%c_effect h2;square;h2;type;GreatFind;persistent;true] A very nice move, preparing Ng3 to exploit the weakness of the f5-square. 18... f6e4  19. c3e4  19... d5e4  20. f3h5  20... g8h7  21. e2c3 White is a bit better because of the passed d-pawn and Black's overextended pawn structure. 21... f7f5  22. h5e2  22... d7f6  23. a1d1  23... a8d8  24. h2e5  24... e7b4 [%c_effect b4;square;b4;type;GreatFind;persistent;true] 25. e5f6  25... f8f6  26. e2c2  26... h6h5 An agressive move. The game is high-level. 27. c3e2  27... b7b5  28. h3h4 [%c_effect h4;square;h4;type;GreatFind;persistent;true] A good move, getting the f4-square for the knight. 28... d8g8  29. h4g5  29... g8g5  30. e2f4  30... e6c6 A curious square for the queen, not afraid of the d-pawn advance. 31. c2e2  31... b4d6  32. d4d5  32... c6b6  33. f4e6  33... g5g4  34. f2f3  34... e4f3  35. e2f3  35... d6e5  36. f1f2  36... h7g6 The idea of this move is to protect the h5-pawn and prepare the move Rg3. 37. e6f4  37... g6h6  38. g1f1  38... b5b4 [%c_effect b4;square;b4;type;GreatFind;persistent;true] 39. f2e2 [%c_effect e2;square;e2;type;Inaccuracy;persistent;true] 39... a7a5  40. e2c2  40... c4c3  41. f4d3 [%c_effect d3;square;d3;type;Mistake;persistent;true] A losing mistake. 41... g4g3  42. f3f2  42... b6b5 [%c_effect b5;square;b5;type;Inaccuracy;persistent;true] 43. f2e2  43... b5d5  44. d3b4 [%c_effect b4;square;b4;type;Inaccuracy;persistent;true] 44... d5e4  45. b4d5  45... f6g6  46. d5f4  46... e5f4  47. e3f4  47... e4f4  48. e2f2  48... f4g4 [%c_effect g4;square;g4;type;Mistake;persistent;true] This move throws away the win. 49. d1e1 [%c_effect e1;square;e1;type;Mistake;persistent;true]
