    On account of the well-known drawish tendencies of many rook endings it is frequently necessary to display great accuracy in order to transform an advantage into the full point. In the present case, Cheparinov exploits his activity well:

    39.h5! following the known motto: passed pawns must move forward. Here the advance of the h-pawn serves above all to shut the black king off on the h-file. [39.Rg1? on the other hand, allows counterplay by means of 39...b5 ]

    39...Kg5 [39...Kxf5? is countered by 40.Rh1! , because the black king can no longer stop the h-pawn: 40...Kf6 41.h6 Kg6 42.h7+- ]

    40.Rg1+! Kh6 [after 40...Kxh5? the white monarch plugs the gaps in the mating net: 41.Kf4 Kh6 42.Ke5 and Black has to surrender too many pawns to avoid being mated.]

    41.f6 Ra2? The final chance to rip apart the net was [41...Ra6 42.Rg8 b5 , however, after 43.Rh8+ Kg5 44.f4+ Kf5 45.Rc8 White has good winning chances.]

    42.Rg7 Kxh5 43.f4 and Jakovenko resigned, because the white king makes a decisive entry, e.g.:

    43...a5 44.Ke4 a4 45.Kf5 Kh6 46.Rxf7 a3 47.Rf8 Kh7 48.Ra8+- 1-0
