25...Rb6!
White is given a frightful choice: either he must concede control of the b-file or else exchange on b6, when Black is given a lever with which to prise open the white center pawn structure.
26.Rxb6 axb6 27.Qb3
The exchange of queens doesn't help much, but if Harrwitz had just waited he could be assailed with ...Ra8 and ...b6-b5, when the a3-pawn would be a target for the black queen.

15...Qa5!
This activity is all very well, but has the d6-pawn been abandoned to its fate?
No, because 16.Rxd6 is met by a 'global' combination that harasses the white pieces on the queenside, center, and kingside: 16...Ne5! 17.b3 (to defend c4) 17...axb3 18.axb3 Bxh3! 19.Bxh3 Nf3+ 20.Kf1 Nxe1 21.Kxe1 Nxe4 22.Rd3 Nxc3! 23.Nxc3 Qa1+ 24.Nd1 Ra2 with a huge initiative to Black.
16.Bf1
A poor square for the bishop. Actually, having gone this far, Reshevsky should probably have tried 16.Rxd6 anyway but, after 16...Ne5 , returned the pawn with 17.Rdd1! Nxc4 18.Bd4!, as played by Smyslov. White can't rejoice at having exchanged his c-pawn for the d6-pawn, but at least he gets rid of Black's strong dark-squared bishop.
16...Ne5 17.Nd4
The fact that the knight returns to d4 shows that the plan to attack d6 has ended in fiasco.
17...a3
Here it paralyses Reshevsky's queenside, making b4 an excellent outpost for a black knight, and casts a blight over his endgame chances.
18.f4 Ned7 19.b3 Na6!
The black knights take the b4- and c5-squares.
