67th ch-RUS HL Vladivostok 2014.6.6 Position after 24 moves of play. This one is easy! A simple deflection theme, but the lesson is more important: be wary of allowing your opponent’s pawns on the 7th rank!
WHITE TO PLAY AND WIN!

67th ch-RUS HL Vladivostok 2014.6.5 Position after 22 moves of play. A complicated game up until Black’s last move (22…Qe8?; instead of 22…Qxg2! with mutual chances). Black had only considered 23. Nxg6 (23.Nd5?! Qf7!) 23…PxN 24.Rdh1 RxR! 25.QxR+ Kf7 and Black survives.
WHITE TO PLAY AND WIN!

67th ch-RUS HL Vladivostok 2014.6.7 Position after White’s 26th move (26.h4?) Once more, like most of the games at this Russian Championship, a tense and complicated struggle up to White’s last move. Black had gambitted several pawns earlier, but did not impress White who took everything. Had White played 26.Rag1 then it would be up to Black to find ways not to lose…but White allowed himself to be overly concerned about a check on h4…
BLACK TO PLAY AND WIN!

67th ch-RUS HL Vladivostok 2014.6.6 Lysyj,I–Maletin,P: 25.Qe2! (or to d3) 1-0 After 25…Qxe2 26.Rxc8+ Bf8 27.Rxf8+ Kxf8 28.c8=Q+ Kg7 29.Be5+f6 30.Nd4 it is a massacre.
67th ch-RUS HL Vladivostok 2014.6.5 Fedoseev,Vl–Vorobiov,E: 23.Nf5+! 1-0 Black overlooked this fine move. If Black moves his King to f7 there is a fork on d6; if instead he moves to g8 then White captures on f6 and Black is helpless.
67th ch-RUS HL Vladivostok 2014.6.7 Belous,V–Matlakov,M: 26… Rc2+!! 0-1 White overlooked Black’s last move. If he takes the Rook then there follows …Rd2+ and …Qg2; if 26.Ke1 Qg3+! 27.Ke1 Qf2!
