Moscow Open A 2016.1.31 IM (2395) Vorontsov, Pavlo–GM Korobov, Anton. Position after Black’s 29th move (29…Qc5). A balanced, but dynamic situation on the board. White’s extra pawn is meaningless, while Black must watch out for the defence of his d-pawn. To his credit, Black has the c-file, but it is difficult to see how to use it. (Had there been another minor piece on the board, perhaps this factor might tilt things in Black’s favour…as it is having only one minor piece limits chances)
In the position above, White should proceed cautiously with 30.Kg2 followed by 31.Kf1 and await a draw offer. Black can not do anything without risking…HOWEVER, under the impression that he had the advantage, White proceeded rashly:
White is trying to be clever, wanting to trade Queens when the ending is better for him. For example, 30…QxQ 31.PxQ Be7 (30…Rxc4 31.Nxd6 and the passed d-pawn will become very dangerous.) 32.Rc1 followed by the advance of his King over to the Queenside. Nor is the ‘solid’ 30…Be7 good enough after the forceful 31.Rc1! However, in his rush to ‘prove’ his advantage, White overlooked a small detail…do you see it?
BLACK TO PLAY AND GET A CLEAR ADVANTAGE!
Moscow Open A 2016.1.31 Vorontsov, Pavlo–Korobov, Anton: 30…Qf2!! Surprise! If now 31.Qxc8+ Kg7 32.Rg1 Bf4 and with the White Queen off on a fishing trip the White King is helpless to defend the mating attack. Neither 31.Qf1 is sufficient after 31…Qxa2 32.Nxd6 Bf4 33.Qg2 Rc2 and White can not hold out much longer. The game continued 31.Rf1 Rxc4 32.Rxf2 Rc1+ 33.Kg2 Be3! and Black won by technical means: 34.Rf1 Rc2+ 35.Kh1 Bc5 36.f4 exf4 37.Rxf4 Rxa2 38.e5 dxe5 39.Rc4 Bb4 0-1
