Qf2 Ra7 {To get into the Black fortress, White must do something about the barrier at f6 and g7.} 25. g5 O-O {Black seems to have castled to safety, but in fact White will now slam the door shut and trap the enemy king.} 26. g6 f5 {This defends the pawn at h4 by opening up a diagonal for the Black queen. Botvinnik realizes that if he can win the pawn and bring the queen to the h-file, then that will wrap things up. But how to deflect the queen?} 27. Rb8 {Black resigned, because the queen must leave the diagonal, since the knight at d5 controls e7 and f6, and the bishop at e3 controls g5. And when the queen moves, Black's defense collapses.} 27... Qxb8 28. Qxh4 Rc8 29. Qh7+ Kf8 30. Qh8# 1-0
