Black wants to repel White's rook with ... b7-b6 now that the a6-pawn is supported.38.c4b6!The point, repelling White's rook.39.Ra1dxc440.Rc3?(40.f3White is fighting to equalize here, but this is best.gxf341.gxf3exf342.Kxf3Re6=)b5∓Black's king has safely remained on the strong f5-square defending the e4-pawn without being restricted by the pin along the fifth rank now that the rook has been kicked off the a5-square.38.c4!...White has softened up Black's defenses and should soon enjoy the more active rooks with threats along the a-file.38....Rc839.Rc3...White's e3-rook comes to life!39....Rff840.Rc5Rcd841.b5cxb542.cxb5Rf7?!42...a5Black's best was to keep the queenside files more closed.

Even if White chases down the a-pawn, it comes at the cost of White's rook's prime placement.47.Ra8Kd648.Rxa5Rh8!=The b5-pawn will fall as soon as White does anything with the rook, and the scope of "anything" that White's rook can do has been drastically restricted without the Ra5-a8 resource.43.bxa6bxa644.Rb3Rd6?44...Rfd7was stronger than abandoning the back rank.45.Rb8...White's rooks will get behind Black's pawns, but the game remains massively complex.45....Kf646.Rh8Kg647.Rg8+Rg748.Rxg7+Kxg749.Kf4Rf6+50.Ke3Rd651.g3Kg652.b4Kf553.Ra5Ke654.Kf4Rb655.Kg5Rxb456.Rxa6+Ke757.Rf6?...The wrong way! White seeks out the appearance of activity, in contrast with Ra6-a2, but, as we will see, the rook is more passive here than on the second rank (where it can move laterally to attack the d-pawn).57.Kxh5Rxd458.Ra2Passive defense suffices here, because The king will support the kingside pawns.Rd359.Kxg4Rf360.h5d461.Re2+−A key detail: the passive defense isn't so passive after all, as the rook is well-placed to attack Black's pawns as soon as the d-pawn attempts an advance.57....Rxd458.Rf4Rd2??Black likely only calculated 59. Kxh5 Re2 60. Rxg4 and 60. Kxg4, but White has a secret third alternative that wins now.59.Kxh5Re260.Rxg4??...A massive miscalculation, passing up both the lone winning move and many moves that left Black fighting to prove the draw.

In contrast, Black's pawns are in perfect harmony and about to receive back-up support from their king.63.Re8+Kd564.g4e365.g5e266.g6Rf5+White's rook is cut off!67.Kg4Re568.Rd8+Kc669.g7e1=QNow it is Black who has the mating net after mutual promotion.70.Rc8+...70.g8=QQg1+71.Kf3Rf5+72.Ke4Qb1+!73.Kxd4Qd1+74.Kc3Rf3+-+70....Kd771.Rd8+...White sacrifices the rook to promote with check, since the alternative is getting mated.71....Kxd872.g8=Q+Kd7White can keep checking for the moment, but there is no perpetual.73.Qf7+Kd674.Qf8+Kd575.Qf7+Kc576.Qc7+Kb477.Qb6+Kc378.Qc7+Kd279.Qa7Qg1+80.Kf4Qh2+81.Kf3Qh3+82.Kf4Qf5+With mate three moves away, White resigned.0-1
