Re2 Rb8 34. e5 Nxf3 35. Nxf3 Kh6 36. Re4 g5 37. exf6 Bxh3 38. Ne5 Qf5 i arrive at the tournament hall after black play his 38th move and and the game is already in the critical position.

39.Re2 Rb2?! a risky move by the Uzbek GM . Fritz said that black should get rid the dangerous f6 pawn first with 39...Rxf6 and the game would be more or less equal. 40. Nc4 Rxc2 consistent with his previous move but objectively speaking black should admit his mistake and play 39...Rbb8 but GM will always show confident especially against lower rated opponents ! 41. Rxc2 ?! Rxf6 42. gxh3 Believe it or not, now Zhang is a rook up and had a winning position but in highly complicated game anybody can made a mistake later . 42...Qxd3 At this particular point, i invite GM Drazen Sermek to check the Fritz evaluation with my notebook. At first i told Drazen that Fritz give 43.Qe7 as the main chooise and Drazen was quite surprised ! He think 43.Qe2 should be better so we rush to my Notebook and see that both move were given more or less the same evaluation. 43. Qe7 Qxc2
[43...Kg6 44.Qe8+ Kg7 45.Qe2 Qxh3+ 46.Kg1 Qg3+ (46...Re6 47.Qf1!) 47.Qg2 Be3+ 48.Nxe3 Qxe3+ 49.Kh1 Rf3 50.Qg1 Rh3+ 51.Rh2 - this analysis is part done by GM Draze Sermek - using my Fritz ! ] 44.

51...Qe1+ 52. Qg1 Qe4+ 53. Qg2 Qxb1 which unfortunately gave black a full rook ! The best move , which are actually hard to find is ( 51.Qb7+ Kh8 52.Qc8+ Kg7 53.Qd7+ Kg8 54.Rxc1 Qxc1+ 55.Nd1) 54. Qb7+

54...Kf6 ? probably the correct idea is to play 54...Kh6 And not let white's queen to come nearer. 55.Qxa6+ (55.Qc6+ Qg6) 55...Qg6 56.Qxg6+ Kxg6–+ Bishop versus knight endings with pawn on both side usually gave advantage to the bishop ) 55.Qc6+= Kf5 [55...Kf7 56.Qd5+ Kg6 57.Qe6+ The queen come nearer and black can avoid perpectual. 57...Kh7 58.Qf7+ Kh6 59.Qf6+ Qg6 60.Qh8+] 56.Qxc5+ Ke4 [56...Kg6 57.Qd6+ Kh7 58.Qe7+ Kh6 59.Qf6+ Qg6 60.Qh8+] 57.Qc4+ Kf3 58.Qf1+ Kg3 [58...Ke3 59.Qe1+ Kd4 60.Qb4+] 59.Qg2+ Kh4 60.Qf2+ Kxh3 61.Qf3+ Kh4 62.Qf2+ Kg4 63.Qg2+ Kf4 64.Qf1+ Ke4 65.Qc4+ Ke3 66.Qb3+ Ke4 67.Qc4+ Kf3 68.Qf1+ Ke3 69.Qe1+ Kf4 70.Qf1+ Kg4 71.Qg2+ Kf5 72.Qd5+ Kf6 73.Qd6+ Kg7 74.Qe7+ Kh6 75.Qf6+ ½–½ black can't avoid perpectual.
