Not only is the pawn ready to torture the white king in case it castles long, it also opens the a5-square for the queen. 12. f3d2  12... c7c6  13. g4g5  13... f6e8  14. h3h4 One of main the points behind White's system. He will not give up the kingside without a fight. 14... d8a5  15. a1b1 Quite an obvious move. 15... e8c7  16. h4h5 [#] 16... f8c8 It is very tempting to x-ray the opponent's queen while freeing a spot for the bishop. 17. e1f1 The king should be safe here. 17... c6d5 It seems as Radjabov achieved everything that he wanted. 18. e4d5 A grand concept $1 18... d7f5  19. c2d1 That is the point: Maghsoodloo is good to give up an exchange for full light-squared control. 19... c7a6  20. a2a3  20... a5d8 Radjabov simply ignores the temptation. 21. f1g2  21... d8d7  22. h5g6  22... f7g6 Half-open file at last $1 Counterplay $1 23. h1h4  23... c8f8  24. d1h1  24... f5b1 Finally, Black captures the rook. And he is also removing the queen away from the attacking position. 25. h1b1  25... d7e7  26. b1h1  26... g7h8 A serious error. 27. e2g4 Now Maghsoodloo is in full control. 27... a6c7  28. e3c5 Just wins. 28... d6c5  29. d2e4  29... a8a6 A sad way to defend, but what else $2 30. d5d6 The most obvious win. 30... a6d6  31. e4d6  31... e7d6  32. h4h7  32... h8g7  33. c3e4  33... d6c6  34. f2f3 One solid-looking move in a sharp situation is all it takes to turn it back into unclear $1 34... c7e6  35. g2g3 A sensible move, to step away from the possible knight checks. 35... e6d4  36. e4c3  36... c6d6  37. c3d5  37... e5e4 Very tempting. 38. f3f4  38... e4e3  39. d5f6  39... g7f6  40. h7d7 Maghsoodloo might have counted on that blow, alas... 40... d4e2 There is a counterblow $1 41. g3h3  41... e2f4 Black wins loads of material and the game after 42. h3h2  42... d6e5  43. h1b7  43... e5g5  44. h2g3  44... f6e5  45. g3f3  45... f4e6  46. f3e4  46... g5g4
