(The positions on the left are odd-numbered; on the right even-numbered)

1) Asian Continental w Tashkent 2016.5.28  Tokhirjonova, G–Yuan, Ye: 21.g4!  This surprising move wins a piece and the game! After 21…hxg3 22.hxg3 g6 23.g4 etc. The game continued 21…Bb7 22.gxh5 Qc6 23.Rhf1 Rxh5 24.Nd2 Bg5 25.Qe2 g6 26.Be4 1-0

2) Asian Continental w Tashkent 2016.5.27  Soumya, Swaminathan–Nadirjanova, Nodira: 27.Bxh5!  A simple but elegante tactic 27… Rxh5 28.Qxh5! Nf8 29.Ng7+ Kd7 30.Rf7+ 1-0

3) Asian Continental  Tashkent 2016.5.29  Kasimdzhanov, Rustam–Lalith, Babu M R:  A wild position that requires courage from Black. In the game continuation Black played the imprecise 29…Rg4, which is not immediately losing, but his next every move was imprecise and he soon lost the game. Possibly he was short of time.  However, he can force an immediate draw with 29…Qc1+! 30.Kg2 Nf4+ 31.Kf3 Re6!! (Threatening …Qh1+)  Now taking with 32.Rxe6 Nxe6 gives Black the better chances, so White should content himself with 32.gxf4 Qh1+ 33.Kg3 Qxe4 34.Qh8+ Kg6 35.Rg8 Kf5! And the game will end in perpetual check as the readers can easily verify

4) Asian Continental  Tashkent 2016.5.28  Le, Quang Liem–Kazhgaleyev, Murtas: 21.Bxg7!! Curiously, it is the Black Queen that White is angling for! 21… Kxg7 22.Qb2+ f6 23.Rg3+ Kh8 24.Ra3 Qxa3 25.Qxa3 Ne5 26.Nf3 Nd3 27.Qxa7 Rf7 28.a4 Bc4 29.Rb1 c5 30.a5 Kg7 31.Rb7 Rc8 32.Nh4 Be6 33.Qa6 Nf4 34.Qc6 c4 35.Kh2 1-0

5) 17th ch-EUR Indiv w  Mamaia  2016.5.28   Szczepkowska-Horowska, Karina–Zherebtsova, Alexandra: 28.Rxd5! Qxd5 29.Rd1! Qc4 30.Bf3 Rc5 31.b3 1-0

6) 17th ch-EUR Indiv w  Mamaia  2016.5.28   Melia, Salome–Mamedjarova, Turkan: 17.Nh5!! An ambush. Surprisingly, this wins the Queen for two pieces. 17… Nxh5 18.Bg5 Bxd4 19.Bxf6 Bxf6 20.Nd4 Bxd4 21.Qxd4 and White had little problema winning Black resigned on the 30th move.

7) 17th ch-EUR Indiv w  Mamaia  2016.5.28   Zimina, Olga–Fataliyeva, Ulviyya: This is a cute back-rank combination. 28.Qxd7! Rxd7 29.Rxc8+ Rd8 30.Rxd8+ Qxd8 31.Bb7! 1-0  The point is White wins back the Queen and will remain a piece up

8) Gashimov Mem Shamkir 2016.5.28 Karjakin, Sergey–Harikrishna, Pentala: 14.Bxg7!! Well calculated Everything is now forced 14… cxd3 15.Qg5 Ne4 16.Qh6 Bg5+ 17.Nxg5 Qxg5+ 18.Qxg5 Nxg5 19.Bxf8 dxc2 20.Rxd6. Kxf8 21.h4 Nh7 22.Kxc2 And with Rook and 3 pawns for the two pieces, the game is just a question of technique.  White won in 61 moves.
