And the final mistake $1
1. d2d4  1... g8f6  2. c2c4  2... e7e6  3. g1f3  3... b7b6  4. g2g3  4... c8b7 It is quite amusing to see a KID guru fianchetto the other bishop first, but Radjabov will nevertheless get what he knows best sooner than later. 5. f1g2  5... f8e7  6. e1g1  6... e8g8  7. b1c3  7... f6e4  8. c1d2  8... e4d2  9. d1d2  9... d7d6  10. e2e4  10... b8d7  11. a1d1  11... c7c5  12. d4d5  12... e6e5 Here it is, Black is heading to a closed setup, typical for the KID. In doing so, however, he is risking heavily as if he does not succeed to create his counterplay in time, Black can get easily smothered. 13. f3e1 The knight is heading to the optimal square on d3, while opening the road for his f-pawn. 13... a7a6  14. a2a4 Wei wants control on the queenside in order to get a one-sided kingside attack. 14... b7c8 [%c_effect c8;square;c8;type;GreatFind;persistent;true] The bishop belongs on this diagonal. Meanwhile, Black is opening the b-file for his rook. 15. f2f4  15... e7f6  16. e1f3 The knight is trying to control all the important dark squares. 16... a8b8  17. f1f2 [%c_effect f2;square;f2;type;Interesting;persistent;true] Wei is just a step away from his optimal setup. If he got a chance to play the cementing Bg2-f1 move, he would have a solid positonal advantage. That is why Radjabov goes for 17... b6b5 [%c_effect b5;square;b5;type;GreatFind;persistent;true] Just in time. 18. a4b5  18... d8a5  19. g2f1  19... f8e8 Adding pressure to the e4-pawn, and White is practically forced to block the center with 20. f4f5  20... f6d8  21. g3g4  21... d7f6  22. f2g2  22... c8d7 Radjabov does not want to release the queenside tension yet. 23. d2e1 [%c_effect e1;square;e1;type;GreatFind;persistent;true] A nice square for the queen, eyeballing both the flanks. 23... a6b5 It is time for something concrete, as otherwise, White will simply crash through on the kingside after Qe1-h4 and g4-g5 $1 24. c4b5  24... c5c4 [%c_effect c4;square;c4;type;GreatFind;persistent;true] More open files and diagonals are essential for Radjabov's counterplay. 25. f1c4  25... a5b4  26. c4d3 [%c_effect d3;square;d3;type;GreatFind;persistent;true] Still, Wei seems to be in full control of the situation. 26... d8a5  27. e1h4 The last preparatory move. 27... b4c5  28. g1h1  28... a5c3  29. g4g5 [%c_effect g5;square;g5;type;GreatFind;persistent;true] And this time it is Wei who is just in time to deliver a blow on his own flank. 29... f6d5 The only move. 30. e4d5 But that is not optimal. 30... e5e4 [%c_effect e4;square;e4;type;Brilliant;persistent;true] Played instantly, Radjabov finds a way to insert her majesty into the game at once. 31. d3e4  31... c5e3 [%c_effect e3;square;e3;type;GreatFind;persistent;true] 32. b2c3  32... e8e4  33. h4g3  33... e3c3 Black consolidated himself and Wei needs to try the last wave of the attack. 34. f3d4  34... c3c5  35. g5g6  35... h7g6 [%c_effect g6;square;g6;type;Interesting;persistent;true] A risky, but perfectly playable move. Now anything is possible. 36. d4e6 [%c_effect e6;square;e6;type;Interesting;persistent;true] And a brave reply from Wei. In the severe time scramble, both players will try their best for the win, ignoring the risk. The exclamation marks do not come for the objective strength of the move, but for the courage. 36... c5b5  37. f5g6  37... f7e6  38. g3h3 White's attack is big, but is it enough for the win $2 38... e4f4 [%c_effect f4;square;f4;type;GreatFind;persistent;true] Secures the king along the f-file. 39. g2c2  39... e6e5 Missing another golden opportunity. 40. h3h7  40... g8f8  41. h7h8  41... f8e7  42. h8g7  42... e7d8  43. g7h8  43... d7e8  44. g6g7 The last key moment.
