WHAT IS WHITE’S BEST CONTINUATION?
Dubai Open 2014.4.9: Swapnil, S.–Marcos, Marvin: 31.Qxa8!! A typical sacrífice whenever a Pawn has reached the 7th ranfist rank is deprived of an important defender. 31…Rxa8 32.Rd8+! Qe8 There is no good alternative. 33.Rxe8+ Rxe8 34.Rd1 Bxe5 35.Rd8 1-0
Dubai Open 2014.4.8 Tabatabaei, M–Bogner, Sebastian: 30…Rc8! Siezing the open file and threatening …Rh3+. If now 31.Rf1 Rh3+ 32.Rh2 Rc2! ) ( or if instead 31.Kh2 Rg4! ) 31.e7 There is nothing better 31…Rh3+ 32.Rh2 Rxh2+! 33.Kxh2 Rc2+! And mate is not far off )
21st TCh-RUS 2014.4.10 Kostin, Alexey–Parfenov, Viktor N.: 19.Nxd5! Bxd2 ( 19…Bxc5 20.c4 ) 20.Ne7+ Rxe7 21.Rxe7 White has a winning ending. 21… Rxc5 ( Better resistance was to be had with 21…Bb4, though after 22.Rxb7 Bxc5 23.c3 there should be no doubt of the outcome; note that 21…Nxc2? is met by22.Re2 ) 22.c3 Nf5 23.Rxb7 a5 24.Rd1 Bg5 25.g3 Bf6 26.a4 1-0 The coming Rb5 can not be long prevented.
21st TCh-RUS 2014.4.10 Prizant, Jaroslav–Nepomniachtchi, Ian: White can win the game by seizing the initiative and keeping up the pressure: 29.f4! Rxe4 (29…gxf4? 30.Rg1 wins immediately) 30.Qxe4! Re8 ( 30…gxf4? 31.Bd3! Qb7 32.Qxf4 with unstoppable attack ) 31.Qxc6!! The check on e2 is nothing. In practice, however, checks can be scary) 31… Qe2+ ( There is nothing better: 31…Re2+ 32.Kc1 Rxc2+ ( 32…g4 33.hxg4 Bxg4 34.Qxd7 h3 35.Qd6+ Kg7 36.Nc5 ) ( 32…gxf4 33.Qxd7 f3 34.Qc6 f2 35.Qxf6+ Ke8 36.Nd2 ) 33.Kxc2 Qe2+ 34.Nd2 and that is that ) 32.Kc1 Qf3 33.Qd6+ ( 33.Qxd7? Qxc3! When Black wins because of the check on e1! ) 34…Re7 34.fxg5 etc. Black’s position is shattered
