question of whether one side is able to force the other into passivity. This
move quickly threatens 42. ...Qh4 and all sorts of mating nets that
effectively slow White's outside passed pawn to a halt.42.c6(42.Nd6Qh443.Qc2(43.Qe2??Nf4!))Qh443.Qe3Nf444.Ke1!?Ng2+45.Ke2Nxe346.Nxe3Qd847.c7Qc848.Nd5e449.fxe4h550.Nb6Qg4+51.Kf1Qh3+52.Ke2Qg4+42.Qe4...Now, Black's knight is no closer to actually stopping
White's pawn, and Black's queen is no closer to attacking White's king.
White's queen, on the other hand, is helping the pawn move forward, and is
still guarding the rook when it shimmies to an open file next turn. These
judgments help us establish why Black's last move did not really create
activity or limit White's activity.42....Qc843.c6h544.Rb1Qh3+45.Ke1Qh1+46.Kd2Qg247.Rb7Qxf2+48.Kc3Ne2+49.Kb4Qe1+50.Kc5Qg1+51.Qe3Qd152.Rxg7+!Kxg753.Qxe5+Kh754.c7Nc155.Qe7+Kh656.Qe3+Kh757.c8=QNd3+58.Kc6Nb4+59.Kb51-0 White wins.1-0
