Karpov-Kasparov, KK2 16th match game, 1985. Black to play and win.This week's position is from the brilliant 16th match game of Kasparov and Karpov's second titanic encounter. Kasparov's play is, interestingly, more like Karpov's in that it is positional and tight. On move 16, he succeeds in planting a knight on d3, dominating Karpov's position. Move by move, Kasparov gradually restricts his great opponent, bringing him in the middlegame to virtual zugzwang, quite an achievement with so many pieces on the board. On move 34, to get rid of the terrible knight, Karpov is forced to give up his queen for three minor pieces — not a terrible exchange in strictly material terms, except that Black now played 37...Rc1, and after 38 Nb2 Qf2 39 Nd2 Rxd1+ 40 Nxd1 Re1+ Karpov resigned because of 41 Nf1 Rxf1 42 Bxf1 Qxf1 mate.
