Knowing well what Dvoretsky has in mind, this was probably the easiest exercise in the entire book for me [Carsten Hansen] to solve, but for newcomers to the 'doctrine' of Dvoretsky, this is the kind of thing that will quickly open your eyes if you study his material seriously. The answer goes as follows: The immediate exchange on c5 guarantees Black equality. 16…Bxc5! 17 dxc5 Qe7 18 c6 Nb4 19 Nd4 Bxg2 20 Kxg2 Nxc6 21 Nxc6 Qb7 It is time to agree a draw. But in what way is 16...Qb6, as recommended in Encyclopaedia of Chess Openings, worse? That is what Karpov played. The game continued only a few more moves: 17 Qd2 Bxc5 18 dxc5 Bxg2 19 Rfc1 Rfc8 20 Rxc5 Qxc5 21 Ne1 Bxg2 22 Kxg2 Qe7. Draw. Serious consideration should be given to the sacrifice of queen for rook, bishop and pawn. Let us ponder over the position arising after 17 Nxe4! [CH: this is what I was talking about above] 17...Rxc1 18 Rfxc1. White intends 19 e3, then 20 Ne5 and the doubling of the rooks on the c-file. The attempt to exchange a pair of rooks by 18...Qb7 19 Ne5 Rc8 20 Nc3! followed by exchange of knights leads to the creation of a weak pawn at d5. As can be seen, by sacrificing the queen you risk practically nothing, whereas the opponent has to be careful - otherwise White's initiative will become dangerous. In my view, it is harder to play with Black in such a position than with White...
