Qe7!! { So many games come down to the question of whether one side is able to force the other into passivity.

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... Qc8 43. c6 h5 44. Rb1 Qh3+ 45. Ke1 Qh1+ 46. Kd2 Qg2 47. Rb7 Qxf2+ 48.
