The Spanish defense was characterized by the move of white chess. White's third move to box b5, and it's been done long before Lopez. However, Lopez was the first person to understand the indirect pressure of this move on the black center soldier. Therefore, the Spanish opening is also known as the Ruy Lopez opening. The Spanish opening is one of the oldest in the history of chess.
