Attack, Precaution and Defense

Are moves of the Rook Pawns good, bad or do they make little difference? The answer lies in the relative value to the total picture. Curiously, the moves have the atributes of attack, precaution and defense. Sometimes they keep enemy forces from directly approaching a target King. Aggressively, they can spring a Pawn storm from a3 or h3. Truth is, in every Pawn move is an implicit marked weakness, since they cannot move back, every time a Pawn moves, for better or for worse, it projects a structural target. In the following 1927 game, Black unnecessary plays 7.h3, it is intended as precautionary. How could Black anticipate that fifteen moves later the weakness would show? The rude awakening, however, comes with 22.Qxh3! Grandmaster of attack Rudolph Spielmann (photo) applies the final magical touch.
