🔸Round 1
⚪️Mosadeghpour,Masoud (2525)
⚫️Hakemi,Arman (2245)
🔸1-0

A critical moment. Black wastes a lot of time on grabbing the white's pawns.
56... Qxg4??
Instead, he should have played sharply with 56... Qd2! 57. a5 e3 58. Ka4 e2 59. Bf2 Qd1 and now:
A) 60. Qb4 Qxd5 -/+
B) 60. a6?? Qf1 61. Bg3 Be5 -+
57.a5 Qxf5 58. a6 Qe5 59. a7 Qa1+ 60. Kb4 Bb2 61.Kb5 Qa3 62. Qa4 1-0

26-year-old Russian GM throws away the win.
55... Bxb6! 56. Nxb6 Kf4 57. Kc3 Kg3 58. Kxd3 Kxh3 59. Ke3 Kg2
60. Nd5 h3 61. Nf4+ Kg3 62. Ne2+ Kg4 63. Kf2 f5 -+

🔸0-1

33.Nd6??
A carelessness.
33. Qe2 h5 34. Ra1 Bb5 35. Qe1=
Now Khodashenas exploits it well.
33... c4 34. Ba2 Qb6+ 35.Kf1
(35. Kh1 Ng4 -+)
35... Rd8 36. Nxc4 Qc6 37. Qf4 Rc8 38. Rb1 Nd5 39. Qd4 Bxc4+ 40.Bxc4 Qxc4+ 0-1

🔸Round 2
⚪️Noroozi,Omid (2326)
⚫️Mosadeghpour,Masoud (2525)

18. Rb7!!
Omid wards off the threat on his knight indirectly and creates the obvious threat of Rd7 and in some cases Rxa7.
18...Rd8
18... fxe5 19. Rxa7
A)19...Rb8 20. Rxa6 Qc7 21. dxe5 +-
