Back then, this type of move, moving a pawn on the side that your opponent is going to attack, was unthinkable. But chess strategy advances and each generation learns something new. The move h7-h5 has become one of Black's main options against the English Attack and the idea was even carried over to other variations of the Sicilian Defense. 10. c3d5
